numpy not properly built when using python3 #190

If I set up a pip requirement for numpy, I get this error when using python3

ImportError: pypi__numpy_1_16_3/numpy/core/_multiarray_umath.so: undefined symbol: _Py_ZeroStruct

My guess is that the extension module is not being built correctly (See these comments).

Here are the details of my bazel setup

I added a python runtime for python3

# ci/BUILD
py_runtime(
    name = "python3",
    interpreter_path = "/usr/bin/python3",
)

And I force python3 to be used by adding the following to my .bazelrc

# .bazelrc
build --python_top=//ci:python3
run --python_top=//ci:python3
test --python_top=//ci:python3

Is there anything I can do to fix this?

I was able to get numpy to work with python3 by using the fork in PR #85 with pip3_import.

I hope you guys will prioritize getting that merged in.

This is closely related to a few other issues, which have the pip_import Python3 issue at their root. See: #220 (comment)

I reckon this can be closed as a dupe.

Dedupping to #249.
