Fixes #638

LGTM

The test is failing with:

tensorflow.python.framework.errors_impl.NotFoundError: /opt/conda/lib/python3.6/site-packages/tensorflow_addons/custom_ops/activations/_activation_ops.so: undefined symbol: _ZN10tensorflow12OpDefBuilder4AttrESs

Based on tensorflow/addons#574, this is because TF and TFA were built with different compilers. Because we are building TF from source to optimize it for our CPU, it creates a mismatch with the pre-built TFA binaries from pypi.

We should build TFA from source to ensure the compiler match.

Useful change - are you guys moving forward with this?

!pip install tensorflow-addons
import tensorflow_addons

NotFoundError: /opt/conda/lib/python3.6/site-packages/tensorflow_addons/custom_ops/activations/_activation_ops.so: undefined symbol: __cudaRegisterFatBinaryEnd

On latest available docker-python with GPU on.

Yes, we are still planning to move forward with this but we will need a bit more work to build our own wheels. This is on my radar but not on top of my priority list. Hopefully, I should get to it over the next couple of weeks.

Closed in favor #816
