Troubleshooting

Getting the subprocess32 error when installing

This means that a dependency used by matplotlib called subprocess32 is not building, which is generally associated with python 2. The way to overcome this issue is by first installing an older version of matplotlib (this is ok):

pip install matplotlib==1.5.3

Getting a warning on wrong numpy version for tensorflow

This might happen on some older systems with python 2. Overcome by first installing an older numpy version:

pip install numpy==1.14.5
