Unfortunately I'm unable to reproduce the issue with both bpython 0.20.1 and master and numpy 1.19.5. So could you gives us some more info on the installed packages, e.g. versions of six, curtsies, jedi and so on.
erikv85 commentedon Mar 8, 2021
Have the same issue, bpython version 0.18 on top of Python 3.8.5, numpy version 1.20.1.
sebastinas commentedon Mar 9, 2021
@erikv85 Can you try with a more recent version of bpython? Do you have jedi installed?
erikv85 commentedon Mar 9, 2021
@sebastinas Upgraded to version 0.21, problem remains.
jedi: I didn''t have jedi installed (i.e., doesn't show in "pip3 list"), installed 0.18.0, problem remains.
six: 1.14.0
curtsies: 0.3.5

@erikv85 Also on macOS?
erikv85 commentedon Mar 9, 2021
@sebastinas Ubuntu 20.04.2, uname -r -> 5.8.0-44-generic.
sebastinas commentedon Mar 9, 2021
Does that happen within in a virtual env? Is numpy installed in that venv? Is bpython installed in that venv and run from within the venv? (Sorry for all the questions, but I'm still unable to reproduce the issue; even with the same Ubuntu version).
erikv85 commentedon Mar 9, 2021
I'm not very familiar with virtualenv, so I probably didn't install bpython that way.
Re-created it in a Docker image. Something like this:
Finally enter the image (container? ...)
docker exec -u me -it todaybpy bashand try commands as in OP, which will crash.

Thanks @erikv85, I was now able to reproduce the issue.
Iterate over all completers until the first one with succeeding locat…
