The document describes how to use TensorBoard, TensorFlow's visualization tool. It outlines 5 steps: 1) annotate nodes in the TensorFlow graph to visualize, 2) merge summaries, 3) create a writer, 4) run the merged summary and write it, 5) launch TensorBoard pointing to the log directory. TensorBoard can visualize the TensorFlow graph, plot metrics over time, and show additional data like histograms and scalars.

2. TensorBoard:TF logging/debugging tool
• Visualize your TF graph
• Plot quantitative metrics
• Show additional data

3. Old fashion: print, print, print

4. New way!

5. 5 steps of using tensorboard
• From TF graph, decide which node you want to annotate
- with tf.name_scope("test") as scope:
- tf.histogram_summary("weights",W), tf.scalar_summary(“accuracy", accuracy)
• Merge all summaries
- merged = tf.merge_all_summaries()
• Create writer
- writer = tf.train.SummaryWriter("/tmp/mnist_logs", sess.graph_def)
• Run summary merge and add_summary
- summary = sess.run(merged, …); writer.add_summary(summary);
• Launch Tensorboard
- tensorboard --logdir=/tmp/mnist_logs

6. Name variables

7. Add scope for better graph hierarch

8. Add histogram

9. Add scalar variables

10. Merge summaries and create writer
after creating session

11. Run merged summary and write (add summary)

12. Launch tensorboard
• tensorboard —logdir=/tmp/mnist_logs
• (You can navigate to http://0.0.0.0:6006)

13. Add scope for better graph hierarch

14. Add scope for better graph hierarch

15. Add histogram

16. Add scalar variables
