4. Introduction to tensor flow
Tensors, in general, are simply arrays of numbers, or
functions, that transform according to certain rules under a
change of coordinates.
TensorFlow is an open source software library for doing graph-
based computations quickly. It does this by utilizing the
GPU(Graphics Processing Unit), and also making it easy to
distribute the work across multiple GPUs and computers.

5. TensorFlow with GO

6. Common-use-cases
you can find some in the TensorFlow Models
repo https://github.com/tensorflow/models.
we'll use one of them, called Inception to
recognize an
image. https://github.com/tensorflow/models/tre
e/master/research/inception/inception

7. Tensor flow trained model
image with TensorFlow plus Go to reduce Dockerfile.
https://github.com/ctava/tensorflow-go
Download Inception
data: http://download.tensorflow.org/models/inception5h
.zip
Let's start with simple main.go file to test if our
Dockerfile works.

8. Test
reduce my Dockerfile.
https://github.com/ctava/tensorflow-go
Download Inception data: http://download.tensorflow.org/models/inception5h.zip
Let's start with simple main.go file to test if our Dockerfile works.
package main
func main()
{
if len(os.Args) < 2
{
log.Fatalf("usage: imgrecognition <image_url>")
}
fmt.Printf("url: %sn", os.Args[1])
}

9. Build Dockerfile
docker build -t imgrecognition .
docker run imgrecognition https://www.iaspaper.net/wp-
content/uploads/2017/10/Rabbit-Essay.jpg Let's get
our image from the provided URL:
// Get image from URL response, e := http.Get(os.Args[1])
if e != nil {
log.Fatalf("unable to get image from url: %v", e)
}
defer response.Body.Close()

10. Golang https://github.com/sangam14/Tenserflow-golang-docker-image-
recongnition/blob/master/main.go
Let's see:
- NewTensor converts from a Go value to a Tensor
- Build a graph of our image
- Init a session, because all Graph operations in Tensorflow are
done with sessions.
- Run the session to normalize image, using input and output.
- normalized[0] contains normalized Tensor.
- In makeTransformImageGraph we define the rules of
normalization.

11. Also let's skip those warnings:
os.Setenv("TF_CPP_MIN_LOG_LEVEL", "2")
Here we worked with pre-trained model, let's try this program with
something unusual, like ... Gopher.
docker run imgrecognition
https://i.pinimg.com/736x/12/5c/e0/125ce0baff3271761ca61843eccf7985.jp
g
Mouse?? no! But it's possible to train our models from Go in TensorFlow.
