Addons: Package Addons for python3.7

[seanpmorgan]

Using the current docker image, we're unable to install / build TensorFlow in python3.7 with the following error:

ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /root/miniconda2/envs/py37/lib/python3.7/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so)

It seems like we need to compile using Ubuntu 16.04 libs, which will require a bump in the custom-op docker image. @yifeif would it be possible to bump the base image in the container? If so we can rebuild our release as 0.1.1 and include py37.

Alternatively, we could create a new docker image for builds.

@dynamicwebpaige Paige, tf-2.0-preview has supported python 3.7 in https://github.com/tensorflow/tensorflow/issues/25429 . Could you tell us how did you do it?

[seanpmorgan]

cc @gunan. Is ubuntu 14.04 being used for the build or some other docker image?

[gunan]

For python 3.7, we had to base our builders off of ubuntu 16.04.
Everything else uses ubuntu 14.04

[yifeif]

We will definitely need a new image for python3.7.

[seanpmorgan]

Addons 0.2.0 has a py37 available on pypi

[seanpmorgan]

Bumping to ubuntu16+GCC5 caused issues issues as seen here in the most recent builds of TF:
https://github.com/tensorflow/tensorflow/issues/27067

This will remain unsolved until the manylinux2010 toolchain is finalized. See #119

What's the ETA for tf addons python 3.7 support?

[seanpmorgan]

@perfinion is there an ETA for the updated build environment / ETA when TF pip packages will be built in it? Just for reference python 3.8 release is soon.

[seanpmorgan]

Looks like this is almost ready:

@av8ramit Could you comment on the above question?

[av8ramit]

Ideally worst case within two weeks we will transition over. Waiting on one last issue with GPU custom ops.
