which doesn't make much sense, as it would mean that somehow it's using a system numpy/scipy instead of the one in the created virtualenv.

Since the virtualenv is created with virtualenv --system-site-packages the system numpy and scipy packages installed on the Travis CI Ubuntu image are used.

I don't think versions of numpy or scipy changed there, so this might be due to the pytest 3.8 release that modified how warning found during collection are handled.
