pip install fails on Windows

[jsiegle]

The call to pip install -q -U pip in the tox.ini file is failing on my Windows machine:

ERROR: InvocationError for command 'C:\\Users\\svc_neuropix\\Documents\\GitHub\\ecephys_spike_sorting\\.tox\\py36-test\\Scripts\\pip.EXE install -q -U pip' (exited with code 1)

What is the purpose of this command, and how should this problem be addressed?

All of the other commands in the tox file run fine if I comment out that line.

This command bootstraps pip (-U is upgrade). If excluded, you may not have the latest pip when running the other commands, which does not seem like a major tragedy.
