AttributeError: 'NoneType' object has no attribute 'shape'

I wanted to use train_tf.py, but the TensorFlow version used in the project is really old, and I guess they are not available anymore. I converted train_tf.py to the tf2 version by using tf_upgrade_v2. And now I am getting this error as I'm running train_tf.py:

This is most likely caused by a missing image file in your dataset. You can try my suggestion from #134 to help identify the problem files.

[baranaldemir]

@haydengunraj Yeah seems like I have the same issue mentioned here #127. How can we fix this?

[haydengunraj]

Ah I see, we're in the process of fixing a couple of different dataset-related issues (including this one) which should be pushed along with the next release. In the meantime, I'd advise trying some of the the suggestions from #126 and #127.

[haydengunraj]

I believe this is now fixed in the v8 release, but feel free to reopen if this is not the case.
