python-pytest and python3-pytest are installed in completely separate
directories, see


python-pytest cannot be invoked by python3.

So uninstalling python-pytest cannot help to solve the issues that your
patches cause.

You know that python on most distros will call python2. So if you want
to call python3 do it explicitly.

virtualenv would only needed if you had different releases of python3
packages that do not fit together.
