How to visualize TensorFlow protobuf in Tensorboard

Tensorboard is a browser based visualization tool for the training of deep learning models using TensorFlow. It is typically invoked on the log directory that is output from the TensorFlow training process. It is not straightforward to use it to visualize a model stored as a single protobuf (.pb) file.

Here is how to do that:

$ pip3 install -U --user tensorflow tensorboard
$ python3 ~/.local/lib/python3.6/site-packages/tensorflow/python/tools/import_pb_to_tensorboard.py --model_dir foobar_model.pb --log_dir foobar_log_dir

This script creates a log directory you requested for if it does not exist. It creates a file name of the form events.out.tfevents.1557253678.your-hostname that Tensorboard understands. Note that it is better to pass in a different log directory for every different model.

Another thing to note is that the option is named --model_dir but it actually expects a protobuf file as input.

$ tensorboard --logdir=foobar_log_dir

The tensorboard executable file should be present in your ~/.local/bin directory. If this path is not in your PATH environment variable, consider adding it. Alternatively, you can invoke the executable with its absolute path too.
