Import completion of numpy isn't working for me, I tried Python 3.7 and 3.6. However I bet this is cause by #845 and I just haven't gotten to the directory that numpy is in yet.

tomb ~$ virtualenv importest
Using base prefix '/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7'
New python executable in /Users/tomb/importest/bin/python3.7
Also creating executable in /Users/tomb/importest/bin/python
Installing setuptools, pip, wheel...done.
tomb ~$ source importest/bin/activate
(importest) tomb ~$ pip install --quiet bpython numpy
(importest) tomb ~$ bpython
bpython version 0.19 on top of Python 3.7.7 /Users/tomb/importest/bin/python3.7
>>> import num<tab>

numpy doesn't complete!
