Fixing Problem in TensorFlow Debugging

To restore the problem, edit debug_mnist.Py, changing the unique line:

Numerical-stable implementation of move-entropy:

Rerun with -debug flag as given below:

At the tfdbg> prompt, enter the below given command:

Declare that no tensors are flagged as containing nan or inf values, and accuracy to maintains and prevent to getting stuck.

Debugging tf-learn Estimators and Experiments

An experiment is an assembly in the tf.Contrib.Examine at a better degree than the Estimator. It gives a single interface for education and comparing it to the model. To debugging the teach () and evaluate () calls to a test object, we can use the keyword arguments train_monitors and eval_hooks when calling its constructor.

Example:

From tensorflow.python import debug as the tf_debug

The LocalCLIDebugHook also allows us to configure a watch_fn that can used to flexibly specify the Tensors to watch on one of a session.Run() calls, like a characteristic of the fetches and feed_dict the different states.

Debugging Keras Models with the help of tfdbg

To use the TFDBG with Keras, allow the Keras backend to use a TFDBG-wrapped consultation item. To use the CLI wrapper in the debugging process:

Debugging tf-slim with tfdbg

TFDBG supports the debugging of training and evaluation with tf-slim. Instruction and assessment require slightly different debugging workflows.

Debugging training with tf-slim

TFDBG supports TensorFlow debugging of training with the help of tf-slender. Training and evaluation make slightly special TensorFlow debugging workflows to work.

Debugging evaluation

To debugging the schooling system, offer LocalCLIDebugWrapperSession to the session_wrapper argument of slender.Mastering.Educate().

Offline Debugging of Remotely-Running Sessions

To perform version TensorFlow debugging in the instances, we may use the offline_analyzer binary of tfdbg. It operates on dumped facts directories. This is done to both the lower-level session API and the better-degree Estimator and test APIs.

Debugging Remote tf.Sessions

In case we have interaction without delay with the tf. Session API in python, we can configure the RunOptions proto that we call your session.Run() technique with, by the usage of the approach tfdbg.

In surroundings that we have terminal access to (as an instance, a nearby laptop that can get admission to the shared garage location exact within the code above), we can load and inspect the records in the selloff directory at the shared storage by way of the offline_analyzer binary of tfdbg.

Example:

Explore Tensorflow Architecture and Important Terms

The session gives an easier manner to generate document-system dumps that may be analyzed offline. To apply it, wrap our consultation in a tf_debug.DumpingDebugWrapperSession.

Example:

The watch_fn argument accept a Callable that permits us to configure the tensors to observe the distinct consultation.Run() calls, like a function of the fetches and feed_dict to run() name and states.

C++ and other languages

If our version code is written in C++ or other words, we can additionally modify the debug_options subject of RunOptionsto to debug dumps that can be inspected offline. See the proto definition for extra information.

Debugging Remotely-Running tf-learn Estimators and Experiments

We could use the non-interactive DumpingDebugHook.

Then this hook can be used in the same manner because the LocalCLIDebugHook examples described earlier on this file. As the evaluation of estimator or experiment takes place, tfdbg creates directories having the following call sample: /shared/garage/place/tfdbg_dumps_1/run__. Each listing corresponding to a session. Run() name that underlie the suit() or compare() call. We can load the directories and inspect them in a command-line interface in an offline way the usage of the offline_analyzer supplied by tfdbg.
