Publish python 3 package

[jkinkead]

The tensorflow-serving-api package is only published for python 2. It should also be published for python 3.

This makes following the tutorial impossible using python 3 - and the tutorial makes no note of the python 2 requirement.

Sorry, tf-serving only supports python 2. See https://github.com/tensorflow/serving/pull/685/files

[jkinkead]

The API package is just a collection of autogenerated classes from proto files. It already supports python 3 as-is, it just needs to be published as such.

I can confirm, that the package supports Python 3 (we're using it on Python 3.6 without any changes). Unfortunately, the package is tagged as Python2 only on PyPI, so it is not possible to simply run pip install ....

At this point we have to do:

1. Download .whl file from PyPI
2. Unzip package
3. Copy&Paste tensorflow_serving/* to our Python3 project

// EDIT: I think this issue should be re-openned. We have a year 2018, Python3 is the future.

[jkinkead]

Adding the --universal flag to this command should be sufficient to get the package labeled as cross-version:

python setup.py bdist_wheel --universal

[jkinkead]

I'm happy to submit a patch fixing the script, but I can't publish or verify on my own.

@illagrenan I Copy&Paste tensorflow_serving/* to my Python3 project, but No moudle named 'tensorflow_serving.session_bundle'.

Folks, the issue is that, at this time, we cannot sign up for the ongoing support of python 3. Please understand that although it may be "easy", for a variety of reasons the cost to us is not zero and we do have to limit our commitments. We will revisit this decision in the future.

[jkinkead]

To clarify: The request is that you label your existing, universal (Python3-compatible) build artifact as such.

We're asking for a label change, not an implementation change. The only Python3 support we're getting is from the gRPC project, not from TensorFlow.

hi ,when the python3 api will be published,thanks.

[illagrenan]

I think there was some misunderstanding - serving supports Python3, the only problem are tags on the PyPI (@jkinkead is right).

I have made Python3 compatible package (I only redistributed official Python package with Python3-compatible setup.py): https://github.com/illagrenan/tensorflow-serving-api-python3. You can now do this:

# Python3 package from https://pypi.python.org/pypi/tensorflow-serving-api-python3
pip install --upgrade tensorflow-serving-api-python3
