How Does One Inspect Variables In A Checkpoint File In Tensorflow When Tensorflow Can't Find The Tools Attribute?

I was trying to inspect checkpoints using the code at inspect_checkpoint.py. However, I wasn't able to have it work because they didn't really provide an example. I tried the simpl

Solution 1:

Try this:

from tensorflow.python.tools.inspect_checkpoint import print_tensors_in_checkpoint_file
print_tensors_in_checkpoint_file(file_name='./tmp/mdl_ckpt', tensor_name='', all_tensors=False)

The all_tensors argument was added since Tensorflow 0.12.0-rc0.

Solution 2:

Well, isn't inspect_checkpoint.py a binary?

Something like this might work:

bazel run tensorflow/python/tools:inspect_checkpoint -- --file_name=YOUR_CKPT

EDIT:

Or without bazel:

Find where tensorflow is installed and run the command with python:

python PATH_TO_VENV/lib/python3.6/site-packages/tensorflow/python/tools/inspect_checkpoint.py --file_name=YOUR_CKPT

For all options, see the file itself: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/tools/inspect_checkpoint.py

Solution 3:

As of latest stable TensorFlow version, 1.13, and in the upcoming TF 2.0, to most straightforward way to inspect a checkpoint is:

path = './tmp/mdl_ckpt' 
get_checkpoint = tf.train.latest_checkpoint(path) 
#this retrieves the latest checkpoin file form path, but it also can be set manually

inspect_list = tf.train.list_variables(get_checkpoint) 

This creates a list of all variable names in given checkpoint

Solution 4:

You could also use the command line interface that uses inspect_checkpoint.

Solution 5:

python -m tensorflow.python.tools.inspect_checkpoint --file_name bad_model/epoch-233

python -m tensorflow.python.tools.inspect_checkpoint --file_name bad_model/epoch-233 --all_tensors

python -m tensorflow.python.tools.inspect_checkpoint --file_name bad_model/epoch-233 --all_tensor_names
