Deploying deep learning models with Docker and Kubernetes

  1. 1. Deploying deep learning models Platform agnostic approach for production with docker+Kubernetes
  2. 2. About this presentation This was originally created to explain the basics of code deployment both in academia and startup environments. ACADEMIA Especially in academia outside computer science departments it is typical that the code developed is very unstructured without much thought on reproducibility or legibility. STARTUPS In smaller startups it is beneficial for all the team members to understand at least something on all the various aspects involved in building a tech product. Based on personal experience, these sort of knowledge gaps between a clinician/biologist and the technical person both in technology and biology can make the teamwork painfully slow.
  3. 3. General “Data Science” Architecture Typical data scientist or researcher may use the “tech stack” on the left. In academia, the code is typically not deployed anywhere, e.g. installing a custom app on the smartphone of a subject in a clinical trial. The researcher simply gather the data with some 3rd party software and then writes some research-grade code to analyze it. In industry, the data science team can consist of multiple roles, and it becomes essential for the organization to have a smooth operation between different roles. In other words, the research and models done by the data scientist can be put in production quickly without major re-writing of the code. ineers-software-engineers-the-difference-according-to-linkedin/
  4. 4. General “BIG DATA/ML” Architecture For example the model developed in TensorFlow might look like this when deployed as product (e.g. as an app for your phone to tell whether your image contains a cat or a dog).

  6. 6. DOCKER Deep learning? Unfortunately that is wrong for deep learning applications. For any serious deep learning application, you need NVIDIA graphics cards, otherwise it could take months to train your models. NVIDIA requires both the host driver and the docker image's driver to be exactly the same. If the version is off by a minor number, you will not be able to use the NVIDIA card, it will refuse to run. I don't know how much of the binary code changes between minor versions, but I would rather have the card try to run instructions and get a segmentation fault then die because of a version mismatch. We build our docker images based off the NVIDIA card and driver along with the software needed. We essentially have the same docker image for each driver version. To help stay manage this, we have a test platform that makes sure all of our code runs on all the different docker images. This issue is mostly in NVIDIA's court, they can modify their drivers to be able to work across different versions. I'm not sure if there is anything that Docker can do on their side. I think its something they should figure out though, the combination of docker and deep learning could help a lot more people get started faster, but right now its an empty promise. The biggest impact on data science right now is not coming from a new algorithm or statistical method. It’s coming from Docker containers. Containers solve a bunch of tough problems simultaneously: they make it easy to use libraries with complicated setups; they make your output reproducible; they make it easier to share your work; and they can take the pain out of the Python data science stack. The wonderful triad of Docker : “Isolation! Portability! Repeatability!” There are numerous use cases where Docker might just be what you need, be it Data Analytics, Machine Learning or AI

  9. 9. Dockervs AWS Lambda ”In General” AWS Lambda will win - sort of.....  From a programming model and a cost model, AWS Lambda is the future - despite so of the tooling limitations. Docker in my opinion is an evolutionary step of "virtualization" that we've been seeing for the last 10 years. AWS Lambda is a step-function. In fact, I personally think it is innovations like Amazon Elastic Beanstalk and CloudFormation that has pushed the demand solutions like Docker.  In the near future, I predict that open source will catch up and provide an AWS Lambda experience on top of Docker containers. is opensource andappearstobe goingdownthispath. FlorianWalker ProductManageratFujitsu Thefutureisnow:)Funktion,partofFabric8,aimsto provideaLamdaexperienceon-topofKubernetes-> JasonDaniels CTO-FujitsuHybridCloudEMEIA projectKratos.. Funktion is an open source event driven lambda style programming model on top of Kubernetes. A funktion is a regular function in any programming language bound to a trigger deployed into Kubernetes. Then Kubernetes takes care of the rest (scaling, high availability, loadbalancing, loggingandmetricsetc). Funktion supports hundreds of different triggerendpoint URLs including most network protocols, transports, databases, messaging systems, social networks, cloud services and SaaS offerings. In a sense funktion is a serverless approach to event driven microservices as you focus on just writing funktions and Kubernetes takes care of the rest. Its not that there's no servers; its more that you as the funktion developer don't have toworryabout managingthem. Announcing ProjectKratos I’m happy to announce that Project Kratos is now available in beta. is rolling out a set of tools that allow you to convert AWS Lambda functions into Docker images. Now, you can import existing Lambda functions and run them via any container orchestration system. You can also create new Lambda functions and quickly package them up in a container to run on other platforms. All three of the AWS runtimes are supported – Node.js, Python and Java.

  11. 11. What is lambda architecture anyway? The Lambda Architecture is an approach to building stream processing applications on top of MapReduce andStorm or similar systems. This has proven to be a surprisinglypopular idea,withadedicated website andan upcomingbook.  Theway thisworksisthatan immutablesequenceofrecordsiscaptured and fedintoa batch system and a stream processing system in parallel. You implement your transformation logic twice, once in the batch system and once in the stream processing system. You stitch together the results from both systems at query time to produce a complete answer. There arealot ofvariationson this. The Lambda Architecture is aimed at applications built around complex asynchronous transformations that need to run with low latency (say, a few seconds to a few hours). A good example would be a news recommendation system that needs to crawl various news sources, process and normalize all the input, and then index, rank, and store it for serving. I like that the Lambda Architecture emphasizes retaining the input data unchanged. I think the discipline of modeling data transformation as a series of materialized stages from an original input has a lot of merit. I also like that this architecture highlights the problem of reprocessingdata (processinginput dataoveragain tore-deriveoutput). The problem with the Lambda Architecture is that maintaining code that needs to produce the same result in two complex distributed systems is exactly as painful as it seems like it would be. I don’t think this problem is fixable. Ultimately, even if you can avoid coding your application twice, the operational burden of running and debugging two systems is going to be very high. And any new abstraction can only provide the features supported by the intersection of the two systems. Worse, committing to this new uber-framework walls off the rich ecosystem of tools and languages that makes Hadoop so powerful (Hive, Pig, Crunch,Cascading,Oozie,etc). Kappa Architecture is a simplification of Lambda Architecture. A Kappa Architecture system is like a Lambda Architecture system with the batch processing system removed. To replace batch processing, data is simply fed throughthestreamingsystemquickly. Kappa Architecture revolutionizes database migrations and reorganizations: just delete your serving layer database and populate a new copy from the canonical store! Since there is no batch processing layer, only one set of code needs to bemaintained. CHALLENGING THE LAMBDA ARCHITECTURE: BUILDING APPS FOR FAST DATA WITH VOLTDB V5.0 VoltDB is an ideal alternativeto the LambdaArchitecture’s speed layer. It offers horizontal scaling and high per-machine throughput. It can easily ingest and process millions of tuples per second with redundancy, while using fewer resources than alternative solutions. VoltDB requires an orderofmagnitude fewer nodesto achievethescale andspeed of the Lambdaspeed layer. Asa benefit,substantiallysmallerclustersarecheapertobuildandrun,and easiertomanage.
  12. 12. Managing containers Enter Kubernetes (from Google)
  13. 13. DOCKER Management enter→ Kubernetes Once every five years, the IT industry witnesses a major technology shift. In the past two decades, we have seen server paradigm evolve into web-based architecture that matured to service orientation before finally moving to the cloud. Today it is containers. Docker is much more than just the tools and API. It created a vibrant ecosystem that started to contribute to a variety of tools to manage the lifecycle of containers.  One of the first tools that Google decided to make open source is called Kubernetes, which means “pilot” or “helmsman” in Greek. Kubernetes works in conjunction with Docker. While Docker provides the lifecycle management of containers, Kubernetes takes it to the next level by providing orchestration and managing clusters of containers. Traditionally, platform as a service (PaaS) offerings such as Azure, App Engine, Cloud Foundry, OpenShift, Heroku and Engine Yard exposed the capability of running the code by abstracting the infrastructure. Kubernetes and Docker deliver the promise of PaaS through a simplified mechanism. Once the system administrators  configure and deploy Kubernetes on a specific infrastructure, developers can start pushing the code into the clusters. This hides the complexity of dealing with the command line tools, APIs and dashboards of specific IaaS providers. 
  14. 14. Containers at scale As has been demonstrated, it is relatively easy to launchtensofthousandsofcontainers  on a single host. But how do you deploy thousands of containers? How do you manage and keep track of them? How do you manage and recover from failure. While these things sometimes might look easy, there are some hard problems to tackle. Let us walkthroughwhatitmakesitsodifficult. With a single command the Docker environment is set up and you can docker run until you drop. But what if you have to run Docker containers across two hosts? How about 50 hosts? Or how about 10,000 hosts? Now, you may ask why one would wanttodo  this. Therearesomegoodreasons why: Two founders of the Kubernetes project at Google, Craig McLuckie and Joe Beda, today announced their new company, Heptio. The company has raised $8.5 million in a series A investmentroundledbyAccel,withparticipation fromMadronaVentureGroup. Open source Kubernetes is a widely deployed technology for container orchestration. Now, Heptiowillbringacommercialversion ofthesoftware to enterprises.
  15. 15. Kubernetes Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon  15 years of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community.

  16. 16. Kubernetes concepts va-ee-application-using-docker-and-kubernetes Inference can be very resource intensive. Our server executes the following TensorFlow graph to process every classification request it receives. The Inception-v3 model has over 27 million parameters and runs 5.7 billion floating pointoperationsper inference. Fortunately, this is where Kubernetes can help us. Kubernetes distributes inference request processing across a cluster using its ExternalLoadBalancer. Each pod in the cluster contains a TensorFlowServingDockerimage with the TensorFlow Serving-based gRPC server and a trained Inception-v3 model. The model is represented as a setoffiles describing the shape of the TensorFlowgraph,modelweights,assets,andso on. Since everything is neatly packaged together, we can dynamically scale the numberof replicatedpodsusing the KubernetesReplicationController to keep up with the service demands.
  17. 17. Alternatives BareMetal Most schedulers with the notable exception of Cloud Foundry can be installed on “bare metal” or physical machines inside your datacenter. This cansave you big onhypervisorlicensing fees. VolumeMounts Volume mounts allow you to persist data across container deployments. This is a key differentiator depending on your applications’ needs.Mesosistheleaderhere,andKubernetesisslowlycatching up. Conclusion There are clearly a lot of choices for orchestrating, clustering, and managing containers. That being said, the choices are generally well differentiated. In terms of orchestration, we can say the following: Swarm has the advantage (and disadvantage) of using the standard Docker interface. Whilst this makes it very simple to use Swarm and to integrate it into existing workflows, it may also make it more difficult to support the more complex scheduling that may be defined in custom interfaces. Fleet is a low-level and fairly simple orchestration layer that can be used as a base for running higher level orchestration tools, such as Kubernetes or custom systems. Kubernetes is an opinionated orchestration tool that comes with service discovery and replication baked-in. It may require some re-designing of existing applications, but used correctly will result in a fault-tolerant and scalable system. Mesos is a low-level, battle-hardened scheduler that supports several frameworks for container orchestration including Marathon, Kubernetes, and Swarm. At the time of writing, Kubernetes and Mesos are more developed and stable than Swarm. In terms of scale, only Mesos has been proven to support large-scale systems of hundreds or thousands of nodes. However, when looking at small clusters of, say, less than a dozen nodes, Mesos may be an overly complex solution.
  18. 18. Kubernetes Still on top? After all, Kubernetes is a mere two years old (as a public open source project), whereas Apache Mesos has clocked seven years in market. Docker Swarm is younger than Kubernetes, and it comes with the backing of the center of the container universe, Docker Inc Yet the orchestration rivals pale in comparison to Kubernetes' community, which -- now under management by the Cloud Native Computing Foundation -- is exceptionally large and diverse. • Kubernetes is one of the top projects on GitHub: in the top 0.01 percent in stars and No. 1 in terms of activity. • While documentation is subpar, Kubernetes has a significant Slack and Stack Overflow community that steps in to answer questions and foster collaboration, with growth that dwarfs that of its rivals. • More professionals list Kubernetes in their LinkedIn profile than any other comparable offering by a wide margin. • Perhaps most glaring, data from OpenHub shows Apache Mesos dwindling since its initial release and Docker Swarm starting to slow. In terms of raw community contributions, Kubernetes is exploding, with 1,000-plus contributors and 34,000 commits -- more than four times those of nearest rival Mesos. I would argue that general-purpose clusters like those managed by Google Kubernetes are better for hosting Internet businesses depending on artificial intelligence technologies than special-purpose clusters like NVIDIA DGX-1. Consider the case that an experiment model training job is using all the 100 GPUs in the cluster. A production job gets started and asks for 50 GPUs. If we use MPI, we'd have to kill the experiment job so to release enough resource to run the production job. This tends to make the owner of the experiment job get the impression that he is doing a "second-class" work. Kubernetes is smarter than MPI as it can kill, or preempt, only 50 workers of the experiment job, so to allow both jobs run at the same time. With Kubernetes, people have to build their programs into Docker images that run as Docker containers. Each container has its own filesystem and network port space. When A runs as a container, it removes only files in its own directory. This is to some extent like that we define C++ classes in namespaces, which helps us removing class name conflicts. An Example A typical Kubernetes cluster runs an automatic speech recognition (ASR) business might be running the following jobs: 1) The speech service, with as many instances so to serve many simultaneous user requests. 2) The Kafka system, whose each channel collects a certain log stream of the speech service. 3) Kafka channels are followed by Storm jobs for online data processing. For example, a Storm job joins the utterance log stream and transcription stream. 4) The joined result, namely session log stream, is fed to an ASR model trainer that updates the model. 5) This trainer notifies ASR server when it writes updated models into Ceph. 6) Researchers might change the training algorithm, and run some experiment training jobs, which serve testing ASR service jobs.
  19. 19. The famous 'classical big data' on Spark Apache Spark has emerged as the de facto framework for big data analytics with its advanced in-memory programming model and upper-level libraries for scalable machine learning, graph analysis, streaming and structured data processing. It is a general-purpose cluster computing framework with language-integrated APIs in Scala, Java, Python and R. As a rapidly evolving open source project, with an increasing number of contributors from both academia and industry, it is difficult for researchers to comprehend the full body of development and research behind Apache Spark, especially those who are beginners in this area. In this paper, we present a technical review on big data analytics using Apache Spark. This review focuses on the key components, abstractions and features of Apache Spark. More specifically, it shows what Apache Spark has for designing and implementing big data algorithms and pipelines for machine learning, graph analysis and stream processing. In addition, we highlight some research and development directions on Apache Spark for big data analytics. In addition to the research highlights we presented in the previous sections, there are other research works which have been done using Apache Spark as a core engine for solving data problems in machine learning and data mining [5,36], graph processing [16], genomic analysis [60,65], time series data [71], smart grid data [73], spatial data processing [87], scientific computations of satellite data [67], large-scale biological sequence alignment [97] and data discretization [68]. There are also some recent works on using Apache Spark for deep learning [46,64]. CaffeOnSpark is an open source project [60] from Yahoo [61] for distributed deep learning on big data withApache Spark.
  20. 20. “BIG Data” Frameworks Apache spark for example
  21. 21. Tensorflow + Apache Spark om/watch?v=PFK6gsnlV5 E TensorFlow-Meetup/ You might be wondering: what’s Apache Spark’s use here when most high-performance deep learning implementations are single-node only? To answer this question, we walk through two use cases and explain how you can use Spark and a cluster of machines to improve deep learning pipelines with TensorFlow: Hyperparameter Tuning: use Spark to find the best set of hyperparameters for neural network training, leading to 10X reduction in training time and 34% lower error rate. Deploying models at scale: use Spark to apply a trained neural network model on a large amount of data. How does using Spark improve the accuracy? The accuracy with the default set of hyperparameters is 99.2%. Our best result with hyperparameter tuning has a 99.47% accuracy on the test set, which is a 34% reduction of the test error. Distributing the computations scaled linearly with the number of nodes added to the cluster: using a 13-node cluster, we were able to train 13 models in parallel, which translates into a 7x speedup compared to training the models one at a time on one machine. The goal of this workshop is to build an end-to-end, streaming data analytics and recommendations pipeline on your local machine using Docker and the latest streaming analytics tools. First, we create a data pipeline to interactively analyze, approximate, and visualize streaming data using modern tools such as Apache Spark, Kafka, Zeppelin, iPython, and ElasticSearch.

  25. 25. Managing Data Storage layer
  26. 26. That is code What about data then? Using the different software above, an application can be deployed, scaled easily and accessed from the outside world in few seconds. But, what about the data? Structured content would probably be stored in a distributed database, like MongoDB, for example Unstructured content is traditionally stored in either a local file system, a NAS share or in Object Storage. A local file system doesn’t work as a container can be deployed on any node in the cluster. On the other side, Object Storage can be used by any application from any container, is highly available due to the use of load balancers, doesn’t require any provisioning and accelerate the development cycle of the applications. Why ? Because a developer doesn’t have to think about the way data should be stored, to manage a directory structure, and so on. The Amazon S3 endpoint used to upload and download pictures is displayed on the bottom left corner and shows that ViPR is used to store the data. The fact that the picture is uploaded directly to the Object Storage platform means that the web application is not in the data path. This allows the application to scale without deploying hundreds of instances. This web application can also be used to display all the pictures stored in the corresponding Amazon S3 bucket. The url displayed below each picture shows that the picture is downloaded directly from the Object Storage platform, which again means that the web application is not in the data path. This is another reason why Object Storage is the de facto standard for web scale applications. Persistent Volumes Walkthrough The purpose of this guide is to help you become familiar with Kubernetes Persistent Volumes. By the end of the guide, we’ll have nginx serving content from your persistent volume. You can view all the files for this example in the docs repo here. This guide assumes knowledge of Kubernetes fundamentals and that you have a cluster up and running. See Persistent Storage design document for more information.
  27. 27. Data Lakes vs data warehouses #1 “A data lake is a storage repository that holds a vast amount of raw data in its native format, including structured, semi-structured, and unstructured data. The data structure and requirements are not defined until the data is needed.” The table below helps flesh out this definition. It also highlights a few of the key differences between a data warehouse and a data lake. This is, by no means, an exhaustive list, but it does get us past this “been there, done that” mentality: Data. A data warehouse only stores data that has been modeled/structured, while a data lake is no respecter of data. It stores it all—structured, semi-structured, and unstructured. [See my big data is not new graphic. The data warehouse can only store the orange data, while the data lake can store all the orange and blue data.] Processing. Before we can load data into a data warehouse, we first need to give it some shape and structure—i.e., we need to model it. That’s called schema-on-write. With a data lake, you just load in the raw data, as-is, and then when you’re ready to use the data, that’s when you give it shape and structure. That’s called schema-on-read. Two very different approaches. Storage. One of the primary features of big data technologies like Hadoop is that the cost of storing data is relatively low as compared to the data warehouse. There are two key reasons for this: First, Hadoop is open source software, so the licensing and community support is free. And second, Hadoop is designed to be installed on low-cost commodity hardware. Agility. A data warehouse is a highly-structured repository, by definition. It’s not technically hard to change the structure, but it can be very time-consuming given all the business processes that are tied to it. A data lake, on the other hand, lacks the structure of a data warehouse—which gives developers and data scientists the ability to easily configure and reconfigure their models, queries, and apps on-the-fly. Security. Data warehouse technologies have been around for decades, while big data technologies (the underpinnings of a data lake) are relatively new. Thus, the ability to secure data in a data warehouse is much more mature than securing data in a data lake. It should be noted, however, that there’s a significant effort being placed on security right now in the big data industry. It’s not a question of if, but when. Users. For a long time, the rally cry has been BI and analytics for everyone! We’ve built the data warehouse and invited “everyone” to come, but have they come? On average, 20-25% of them have. Is it the same cry for the data lake? Will we build the data lake and invite everyone to come? Not if you’re smart. Trust me, adata lake,at thispoint in itsmaturity,isbest suited for the datascientists.
  28. 28. Data Lakes Medical Examples SettingUp the Data Lake Unlike most relational databases' linear representation and analysis of data, Franz's semantic graph database technology employs with which users can graphically see data elements and their relationships. Montefiore also recently started another program using the data lake to do cardio- genetic predictive analytics to determine the degrees of possibility of patients having suddencardiacdeathbasedontheir geneticbackground.

  30. 30. Data science pipeline development and deployment Note! Academia has been notoriously slow to adopt new technologies in academic research, and you should not be afraid of the use of “business analyst” academia. Dockerizing analysis research pipelines for end-to-end reproducibility would be an excellent way reducing “sloppy” science. Peer reviewers (or even the journals automatically) could potentially feed “standardized” datasets via REST APIs at various points of the pipeline to ensure that the methodologies used are of “good science”

Machine Learning. “Keras Inception V3 image classification model Prediction with deployment on Compute Engine w/ Docker & Google Container Registry (like Docker Hub), using Flask Front-end Webserver.” When you have developed and trained your model, the prediction part in development becomes rather easy Flask web server allows fast creation of front-end which you can use for example for quick demo of your minimum viable product (MVP), progress report for your boss, interactive front-end for showing scientific results for your PI (principal investigator).

If you are using TensorFlow (TF) backend, you can use the TF computation graph (i.e. trained model) trained “natively” on TensorFlow with the Keras deployment for example when your data scientist(s) keep on re-training the model, and you can then just replace the computation graph (.ckpt, checkpoint) with the new weights

The article uses the machine learning model trained with TensorFlow. The trained model is exported into a Google Cloud Storage bucket before batch processing starts. The model is dynamically restored on the worker nodes of prediction jobs. This approach enables you to make predictions against a large dataset, stored in a Cloud Storage bucket or Google BigQuery tables, in a scalable manner, because Cloud Dataflow automatically distributes the prediction tasks to multiple worker nodes. Cloud Dataflow is a unified programming model and a managed service for developing and executing a wide range of data processing patterns including ETL (Extract, Transform, Load), batch computation, and continuous computation. Cloud Dataflow frees you from operational tasks such as resource management and performance optimization. Using Cloud Storage as a data source. Using BigQuery as a data source.
  34. 34. Automated Kubernetes GPU Deployment #1 with tensorflow How to automate deep learning training with Kubernetes GPU-cluster By Frederic Tausch Why did I write this guide? I have worked as in intern for the startup and noticed the hassle of firstly designing a machine learning algorithm locally and then bringing it to the cloud for training with different parameters and datasets. The second part, bringing it to the cloud for extensive training, takes always longer than thought, is frustrating and involves usually a lot of pitfalls. For this reason I decided to work on this problem and make the second part effortless, simple and quick. The result of this work is this handy guide, that describes how everyone
  35. 35. Automated Kubernetes GPU Deployment #2 with tensorflow GPUs & Kubernetes for Deep Learning By Samuel Cozannet Deploy Kubernetes with GPUs ● Deploy k8s on AWS in a development mode (no HA, colocating etcd, the control plane and PKI) ● Deploy 2x nodes with GPUs (p2.xlarge and p2.8xlarge instances) ● Deploy 3x nodes with CPU only (m4.xlarge) ● Validate GPU availability Add EFS storage to the cluster ● Programmatically add an EFS File System and Mount Points into your nodes ● Verify that it works by adding a PV / PVC in k8s. Automating Tensorflow deployment ● Data ingest code & package ● Training code & package ● Evaluation code & package ● Serving code & package ● Deployment process So what is a Deep Learning pipeline exactly? Well, my definition is a 4 step pipeline, with a potential retro-action loop, that consists of : Data Ingest: This step is the accumulation and pre processing of the data that will be used to train our model(s). This step is maybe the less fun, but it is one of the most important. Your model will be as good as the data you train it on Training: this is the part where you play God and create the Intelligence. From your data, you will create a model that you hope will be representative of the reality and capable of describing it (and even why not generate it) Evaluation + Monitoring: Unless you can prove your model is good, it is worth just about nothing. The evaluation phase aims at measuring the distance between your model and reality. This can then be fed back to a human being to adjust parameters. In advanced setups, this can essentially be your test in CI/CD of the model, and help auto tune the model even without human intervention Serving: there is a good chance you will want to update your model from time to time. If you want to recognize threats on the network for example, it is clear that you will have to learn new malware signatures and patterns of behavior, or you can close your business immediately. Serving is this phase where you expose the model for consumption, and make sure your customers always enjoy the latest model.
  36. 36. Jupyter notebooks vs IDE development What is the practical difference?
  37. 37. Jupyter notebooks What are they all about If you are a beginner in data science (and with Python) you might have noticed that there are a lot of tutorial implemented as Jupyter notebooks (used to be referred as ipython). The notebooks allow easy embedding of formatted text and images to executable code, which make then very useful to provided with scientific papers and walkthrough example code. Idea of a notebook Both in academia (e.g. non-tech savvy old-school PI vs. new generation data wizard) and in industry, one may want to communicate concisely the rationale for the computing with the results. Compare this to “Excel data science”, where a person manually manipulates the data destroying end-to-end processing pipeline and making reproducible research impossible. In Jupyter notebook, one could include both data preparation and data analysis parts, and the grad student could for example do the dirty work and ask for insight from more senior researchers. In theory, the collaborators would quickly realize that the notebook is about, and allowing quick playing around that would easily usable by the poor grad student as well eliminating the Excel → Matlab/R/Python Excel circus→ probably experienced in some research labs. Downside is that the notebooks are not ‘plug’n’play’ executables, and can depend on a lot of standard libraries, are even worse for a non- tech savvy PI, custom libraries written by the grad student

  47. 47. Streaming Machine learning Databricks #1 pache-spark One way to productionize a model is to deploy it as a Spark SQL User Defined Function, which allows anyone who knows SQL to use it. Deep Learning Pipelines provides mechanisms to take a deep learning model and register a Spark SQL User Defined Function (UDF). The resulting UDF takes a column (formatted as a image struct "SpImage") and produces the output of the given Keras model (e.g. for Inception V3, it produces a real valued score vector over the ImageNet object categories).
  48. 48. Streaming Machine learning Databricks #2 Getting the best results in deep learning requires experimenting with different values for training parameters, an important step called hyperparameter tuning. Since Deep Learning Pipelines enables exposing deep learning training as a step in Spark’s machine learning pipelines, users can rely on the hyperparameter tuning infrastructure already built into Spark. A Vision for Making Deep Learning Simple From Machine Learning Practitioners to Business Analysts by Sue Ann Hong, Tim Hunter and Reynold Xin Posted in ENGINEERING BLOGJune 6, 2017 SIMPLIFY MACHINE LEARNING WITH APACHE SPARK Read the White Paper Download our Machine Learning Starter Kit Deploying Models in SQL Once a data scientist builds the desired model, Deep Learning Pipelines makes it simple to expose it as a function in SQL, so anyone in their organization can use it – data engineers, data scientists, business analysts, anybody. sparkdl.registerKerasUDF("img_classify", "/mymodels/dogmodel.h5") Next, any user in the organization can apply prediction in SQL: SELECT image, img_classify(image) label FROM images WHERE contains(label, “Chihuahua”) Similar functionality is also available in the DataFrame programmatic API across all supported languages (Python, Scala, Java, R). Similar to scalable prediction, this feature works in both batch and structured streaming. Conclusion In this blog post, we introduced Deep Learning Pipelines, a new library that makes deep learning drastically easier to use and scale. While this is just the beginning, we believe Deep Learning Pipelines has the potential to accomplish what Spark did to big data: make the deep learning “superpower” approachable for everybody. Future posts in the series will cover the various tools in the library in more detail: image manipulation at scale, transfer learning, prediction at scale, and making deep learning available in SQL. To learn more about the library, check out the Databricks notebook as well as the github repository. We encourage you to give us feedback. Or even better, be a contributor and help bring the power of scalable deep learning to everyone.

Streaming Machine learning linagora Making Image Classification Simple With Spark Deep Learning Zied Sellami, Jun 28 2017 earning-f654a8b876b8 Apache Spark is an open-source cluster-computing framework. Apache Spark is a fast, in-memory data processing engine with expressive development APIs to allow data workers to efficiently execute streaming, machine learning or SQL workloads that require fast iterative access to datasets. Conclusion Apache Spark is a very powerful platform with elegant and expressive APIs to allow Big Data processing. We tried with success Spark Deep Learning, an API that combine Apache Spark and Tensorflow to train and deploy an image classifier. It is extremely easier (less than 30 lines of code). Our next objective is to test if we can deploy facial recognition model with this API While this support is only available on Python, we hope that integration will be done very soon on other programming languages especially with Scala. Run pyspark with spark-deep-learning library spark-deep-learning library comes from Databricks and leverages Spark for its two strongest facets: In the spirit of Spark and Spark MLlib, it provides easy-to-use APIs that enable deep learning in very few lines of code. It uses Spark’s powerful distributed engine to scale out deep learning on massive datasets. The library run on pyspark.

  51. 51. Industry Use cases
  52. 52. Kubernetes in deep learning #1 Deep learning is an empirical science, and the quality of a group's infrastructure is a multiplier on progress. Fortunately, today's open-source ecosystem makes it possible for anyone to build great deep learning infrastructure. In this post, we'll share how deep learning research usually proceeds, describe the infrastructure choices we've made to support it, and open-source kubernetes-ec2-autoscaler, a batch- optimized scaling manager for Kubernetes. We hope you find this post useful in building your own deep learning infrastructure. Once the model shows sufficient promise, you'll scale it up to larger datasets and more GPUs. This requires long jobs that consume many cycles and last for multiple days. You'll need careful experiment management, and to be extremely thoughtful about your chosen range of hyperparameters. Like much of the deep learning community, we use Python 2.7. We generally use Anaconda, which has convenient packaging for otherwise difficult packages such as OpenCV and performance optimizations for some scientific libraries. We also run our own physical servers, primarily running Titan X GPUs. We expect to have a hybrid cloud for the long haul: it's valuable to experiment with different GPUs, interconnects, and other techniques which may become important for the future of deep learning. Scalable infrastructure often ends up making the simple cases harder. We put equal effort into our infrastructure for small- and large-scale jobs, and we're actively solidifying our toolkit for making distributed use-cases as accessible as local ones. Kubernetes requires each job to be a Docker container, which gives us dependency isolation and code snapshotting. However, building a new Docker container can add precious extra seconds to a researcher's iteration cycle, so we also provide tooling to transparently ship code from a researcher's laptop into a standard image. We expose Kubernetes's flannel network directly to researchers' laptops, allowing users seamless network access to their running jobs. This is especially useful for accessing monitoring services such as TensorBoard. (Our initial approach — which is cleaner from a strict isolation perspective — required people to create a Kubernetes Service for each port they wanted to expose, but we found that it added too much friction.) We're releasing kubernetes-ec2-autoscaler, a batch-optimized scaling manager for Kubernetes. It runs as a normal Pod on Kubernetes and requires only that your worker nodes are in Auto Scaling groups. Our infrastructure aims to maximize the productivity of deep learning researchers, allowing them to focus on the science. We're building tools to further improve our infrastructure and workflow, and will share these in upcoming weeks and months. We welcome help to make this go even faster!

  54. 54. Automated Kubernetes CPU Deployment Baidu Case Baidu's deep learning framework adopts Kubernetes Google's orchestration framework will provide smart resource allocation and cluster management to PaddlePaddle Why Run PaddlePaddle on Kubernetes PaddlePaddle is designed to be slim and independent of computing infrastructure. Users can run it on top of Hadoop, Spark, Mesos, Kubernetes and others.. We have a strong interest with Kubernetes because of its flexibility, efficiency and rich features. A successful deep learning project includes both the research and the data processing pipeline. There are many parameters to be tuned. A lot of engineers work on the different parts of the project simultaneously. To ensure the project is easy to manage and utilize hardware resource efficiently, we want to run all parts of the project on the same infrastructure platform. The platform should provide: ● fault-tolerance. It should abstract each stage of the pipeline as a service, which consists of many processes that provide high throughput and robustness through redundancy. ● auto-scaling. In the daytime, there are usually many active users, the platform should scale out online services. While during nights, the platform should free some resources for deep learning experiments. ● job packing and isolation. It should be able to assign a PaddlePaddle trainer process requiring the GPU, a web backend service requiring large memory, and a CephFS process requiring disk IOs to the same node to fully utilize its hardware. What we want is a platform which runs the deep learning system, the Web server (e.g., Nginx), the log collector (e.g., fluentd), the distributed queue service (e.g., Kafka), the log joiner and other data processors written using Storm, Spark, and Hadoop MapReduce on the same cluster. We want to run all jobs -- online and offline, production and experiments -- on the same cluster, so we could make full utilization of the cluster, as different kinds of jobs require different hardware resource.
  55. 55. Docker customers Published on Aug 11, 2016 In this video Ajay Dankar, Senior Director Product Management at PayPal discusses why they selected Docker and Docker Trusted Registry to help them containerize their legacy apps to more efficiently utilize their infrastructure and secure workloads. -- Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.
  56. 56. Business data into value 8 ways to turn data into value with Apache Spark machine learning OCTOBER 18, 2016 by Alex Liu Chief Data Scientist, Analytics Services, IBM 1. Obtain a holistic view of business In today's competitive world, many corporations work hard to gain a holistic view or a 360 degree view of customers, for many of the key benefits as outlined by data analytics expert Mr. Abhishek Joshi. In many cases, a holistic view was not obtained, partially due to the lack of capabilities to organize huge amount of data and then to analyze them. But Apache Spark’s ability to compute quickly while using data frames to organize huge amounts of data can help researchers quickly develop analytical models that provide a holistic view of the business, adding value to related business operations. To realize this value, however, an analytical process, from data cleaning to modeling, must still be completed. 4. Avoid customer churn by rethinking churn modeling Losing customers means losing revenue. Not surprisingly, then, companies strive to detect potential customer churn through predictive modeling, allowing them to implement interventions aimed at retaining customers. This might sound easy, but it can actually be very complicated: Customers leave for reasons that are as divergent as the customers themselves are, and products and services can play an important, but hidden, role in all this. What’s more, merely building models to predict churn for different customer segments—and with regard to different products and services—isn’t enough; we must also design interventions, then select the intervention judged most likely to prevent a particular customer from departing. Yet even doing this requires the use of analytics to evaluate the results achieved—and, eventually, to select interventions from an analytical standpoint. Amid this morass of choices, Apache Spark’s distributed computing capabilities can help solve previously baffling problems. 5. Develop meaningful purchase recommendations Recommendations for purchases of products and services can be very powerful when made appropriately, and they have become expected features of e-commerce platforms, with many customers relying on recommendations to guide their purchases. Yet developing recommendations at all means developing recommendations for each customer—or, at the very least, for small segments of customers. Apache Spark can make this possible by offering the distributed computing and streaming analytics capabilities that have become invaluable tools for this purpose. ebaytechblog: Spark is helping eBay create value from its data, and so the future is bright for Spark at eBay. In the meantime, we will continue to see adoption of Spark increase at eBay. This adoption will be driven by chats in the hall, newsletter blurbs, product announcements, industry chatter, and Spark’s own strengths and capabilities.

  58. 58. Internet of things (IoT) To proof that our IoT platform is really independent on application environment, we took one IoT gateway (RaspberryPi 2) from the city project and put into Austin Convention Center during OpenStack Summit together with IQRF based mesh network connecting sensors that measure humidity, temperature and CO2 levels. This demonstrates ability that IoT gateway can manage or collect data from any technology like IQRF, Bluetooth, GPIO, and any other communication standard supported on Linux based platforms. We deployed 20 sensors and 20 routers on 3 conference floors with a single active IoT gateway receiving data from entire IQRF mesh network and relaying it to dedicated time-series database, in this case Graphite.

  59. 59. Healthcare How open source container tech can impact healthcare At Red Hat, we believe that creating open source platforms allows the tech community to develop the best software possible. We recently launched a series of films highlighting the open source movement’s impact on healthcare, including initiatives that promote open patient data and provide 3D-printed prosthetics. Health is a great context to start exploring OpenShift’s open source capabilities. We designed OpenShift to allow developers to take full advantage of containers (Docker) and orchestration (Kubernetes), without having to learn the internals of how to build containers from scratch or understand sys admin enough to deploy production-quality apps that can scale on demand. OpenShift makes using containers and orchestration accessible by letting you focus on code instead of writing Dockerfiles and running Docker builds all day. With the integrated Source-to-Image open source project, the platform automatically creates containers while requiring only the URL for your source code repository. Improving Container Security: Docker and More After 6 months and 15 successful beta deployments, Twistlock is announcing the general availability of our container security suite. Twistlock came out of stealth in May 2015. Since then, we have been working diligently with a select group of beta customers to validate the value of our offerings. This diverse group of 15 beta testers, including Wix,AppsFlyer, and HolidayCheck, spans financial services, hospitality, healthcare, Internet services, and government. These customers confirmed that we are hitting the sweet spot of their most pressing container security needs -- a majority of them already deployed our product into their production environments, protecting live services and customer data. The logical resource boundaries established in Docker containers are almost as secure as those established by the Linux operating system or by a virtual machine, according to a report by Gartner analyst Joerg Fritsch. However, Docker and Linux containers in general fall short when it comes to container management and administration, Fritsch said in his report, " Security properties of containers managed by Docker."
  60. 60. Academia Use cases
  61. 61. Neuroscience & bioinformatics Most large-scale analytics, whether in industry or neuroscience, involve common patterns. Raw data are massive in size. Often, they are processed so as to extract signals of interest, which are then used for statistical analysis, exploration, and visualization. But raw data can be analyzed or visualized directly (top arrow). And the results of each successive step informs how to perform the earlier ones (feedback loops). Icons below highlight some of the technologies, discussed in this essay, that are core to the modern large- scale analysis workflow. “Cloud deployment also makes it easier to build tools that run identically for all users, especially with virtual machine platforms like Docker. However, cloud deployment for neuroscience does require transferring data to cloud storage, which may become a bottleneck. Deploying on academic clusters requires at least some support from cluster administrators but keeps the data closer to the computation. … There is also rapidly growing interest in the ‘‘data analysis notebook’’. These notebooks – the Jupyter notebook being a particularly popular example – combine executable code blocks, notes, and graphics in an interactive document that runs in a web browser, and provides a seamless front-end to a computer, or a large cluster of computers if running against a framework like Spark. Notebooks are a particularly appealing way to disseminate information; a recent neuroimaging paper, for example, provided all of its analyses in a version-controlled repository hosted on GitHub with Jupyter notebooks that generate all the figures in the paper [45]—a clear model for the future of reproducible science
