Bug: Missing function register_module_for_export

[renato-arantes]

What happened?

I'm having an issue with TF v2.16 and tensorflow_hub v0.16, which is throwing an error about a missing function register_module_for_export. If I downgrade to tensorflow_hub v0.15, it complains about a missing estimator.py file, that is deprecated in TF v2.16.

Relevant code

import tensorflow_hub as hub

Hi @renato-arantes. Thanks for posting.

Would you mind sharing the output of pip freeze in your environment?

TensorFlow 2.16 has not been released yet at this time. I'm wondering if you might have a different package installed (eg tf-nightly)

Thanks!

Hi @KeijiBranshi,

Yes, when I say TensorFlow 2.16 I mean tf-nightly.

Thanks!

[KeijiBranshi]

Thanks for the clarification. I'm wondering if this is more a TensorFlow+Keras issue, rather than anything related to tensorflow_hub. See the backwards compatibility documentation here.

Do you have tf-keras-nightly installed as well? iiuc, tf-nightly and tf-keras-nightly are released alongside each other. Keras 3 support doesn't come to TF until 2.16 (ie the current nightly version), so their may be incompatibilities between tf-nightly and the current non-nightly tf-keras (see this discussion).

I'm seeing a similar issue as well with version 0.16.0 and newer:

$ pip freeze | grep -i 'tensorflow'
tensorflow==2.16.1
tensorflow-hub==0.16.1
tensorflow-io-gcs-filesystem==0.36.0

and when I run this command:

>>> from tensorflow_hub import *

Although according to this:
https://github.com/tensorflow/hub/blob/v0.16.1/tensorflow_hub/__init__.py#L132
It should be packaged as part of the module.

When I looked under site-packages sure enough a lot of modules here https://github.com/tensorflow/hub/tree/v0.16.1/tensorflow_hub are missing from the installed package:

$ ls site-packages/tensorflow_hub/

__pycache__  config.py                      keras_layer.py  registry.py   tf_utils.py  version.py
