build_ext recipe for setup.py fails with TF2.2 and python3.7

[mshaikh786]

Hello Jonathan,
I got your email contact from the Dockerfile for circle CI in the release tarball of nvtx-plugins 0.1.8

I tried to pip install nvtx-plugins and when importing the module got an error:

python -c ‘import nvtx.plugins.tf’

I assume build_ext need to be run to produce this Cpython object, however

python setup.py build_ext
fails with the following error:
-bash-4.2$ python setup.py build_ext

Any clues?

This project is not tested to be built using python setup.py build_ext.

Please use the following:

python setup.py sdist
pip install -U dist/*

Though I never tried to build the project on Python 3.7. That could be the issue

Hi
With python3.7, your suggested commands fail to creat the cpython library object file.

What is the error you get ?
