[TF 2.0] tf.estimator import error

[Paige Bailey]

TF 2.0 Testers -

For everyone using the tf-nightly-2.0-preview for tf.estimator.Estimator(): the build has been broken since February 12th, and is being actively worked on. If you have experienced an issue with importing estimators, you are not alone!

Thanks to +Mustafa Mustafa for reporting the issue, and for +Goldie Gadde for working on the fix. I will update this post as soon as the issue is resolved, and you can track #25723.

Detailed example of the problem:

>>> import tensorflow as tf
>>> import tensorflow_estimator.python.estimator.api._v2.estimator
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/tensorflow_estimator/python/estimator/__init__.py", line 25, in <module>
    import tensorflow_estimator.python.estimator.estimator_lib
  File "/usr/local/lib/python3.6/dist-packages/tensorflow_estimator/python/estimator/estimator_lib.py", line 54, in <module>
    from tensorflow_estimator.python.estimator.mode_keys import ModeKeysV2
  File "/usr/local/lib/python3.6/dist-packages/tensorflow_estimator/python/estimator/mode_keys.py", line 22, in <module>
    from tensorflow.python.training.mode_keys import ModeKeys
ModuleNotFoundError: No module named 'tensorflow.python.training.mode_keys'
>>> tf.__version__
'2.0.0-dev20190213'
>>> 
>>> exit()

Thanks again for your great work, and for testing!

The issue has been resolved, and a new v2 estimator package is now available for use.

Thanks!

Great! Thank you for the update.

I will wait for the nightly build to test.

[Mustafa Mustafa]

Is there a way to check the status of the nightly build? I don't think today's is available yet.

[Goldie Gadde]

Hi Mustafa, 

The builds were delayed today. They should be available now. I dont know if there is a way to make the status of the build available externally.

Thanks,

Goldie

[Mustafa Mustafa]

Thanks for now Goldie. I will continue the tests later today.

[Mustafa Mustafa]

Hmmm, I feel I might be missing something; the module is still not available in today's build.

Hi, Mustafa -

Could you please try again, running each of your statements individually?

I'm able to see tf.estimator.Estimator() in my version (also 2.0.0-dev20190215):

[Mustafa Mustafa]

Thank you for testing Paige. It still doesn't work, see below.

It works on a different machine. Something odd is going on. Both have the same tf.__git_version__ hash. Must be an issue on my end.

[Paige Bailey]

Thanks for the update, Mustafa! This sounds like it could be a potential environment issue, or a snag with the build. Let us know what you find out!

Fixed.

For some reason, when I uninstall the previous build and reinstall, it doesn't clean up the estimator package installation.

Beautiful! Thank you, Mustafa - and feel free to reach out (chat or email) if you run into any snags. 😊

[Martin Wicke]

If you "pip install -U" on reinstall, would that work?

[Mustafa Mustafa]

Yes, this seems to work. But I might not have been able to reproduce the exact "stale" environment I had earlier.
