Publish to conda-forge

[0x1997]

I installed tensorflow from conda-forge and tensorflow_io with pip. However importing tensorflow_io failed with an error

NotImplementedError: unable to open file: libtensorflow_io.so, from paths: ['/data/miniconda/lib/python3.7/site-packages/tensorflow_io/co

It seems the tensorflow_io wheel on pypi was not built with C++11 ABI. Could you publish a compatible version to conda-forge if you have to support older OSs? Thanks.

We certainly want to support conda-forge. Though I don't have a lot of (or any) experience with conda-forge so it may take some time for me to get this thing going.

[yongtang]

If anyone can help getting this started or some pointers, will be much appreciated.

With GitHub Actions supported (See #645), I think conda-forge support will be easier.

This would be good to have. I don't have much experience with publishing to Conda, but I can give this a shot if no one is able to get to it first.

[yongtang]

@BryanCutler That would be great 👍 ! I will try to see if I can help as well.

[BryanCutler]

I'm looking into this now, will report back soon

It looks like the latest version of TensorFlow in conda is v1.13.2 see https://anaconda.org/conda-forge/tensorflow/files?page=1. Would it be better to hold off on this until TF 2.0 is released in conda?

We've had some discussion about this for tf-addons that may be of use:
tensorflow/addons#201

Anaconda packages a tf2.0 but I'm not sure who is managing the conda-forge version.

Thanks @seanpmorgan @BryanCutler . By looking at https://github.com/conda-forge/tensorflow-feedstock it looks like tensorflow-feedstock repo is not well maintained. The last update was 09/30/2019 which is 3 months old.

Wondering if there is a way to move forward the tf 2.0 in conda-forge?

@yongtang There is already an open PR to update to 2.0 conda-forge/tensorflow-feedstock#97 generated by the bot. Either fix this PR or port the way Anaconda builds tensorflow to conda-forge: https://github.com/AnacondaRecipes/tensorflow_recipes

[yongtang]

Thanks @xhochy. Not very familiar with conda recipes/feedstock but I will try to take a look.

Created a working in progress PR conda-forge/tensorflow-feedstock#101

Still too many issues to build. One dependency is the Bazel. When building Bazel gcc version is old. need more time to moving forward.
