I was able to use venv and install tox and tox-pyenv locally to use tox. I also installed pyenv with brew. I had many problem with scientific packages in python projects mostly, the incompatibility between different versions of libraries, I use Conda for those projects, and venv for other projects not dependent on numpy and scikit-learn.
