jedi support in spyder 4
(Spyder maintainer here) Spyder 4.0.0 and 4.0.1 only work with Jedi 0.14.1. Newer nor older versions are supported, so be sure to have that exact version installed.
By the way, although not required, Kite completions are better for scientific packages than Jedi ones.
I updated to Spyder 4 (4.0.0?) to get the latest and greatest features. At this time I found out that Spyder now has the option of using Kite for autocompletion. After trying Kite for a bit I wanted to revert back to the previous autocompletion setup. I thought this was possible by unchecking to use Kite in the preferences, but then autocompletion seemed to be completely broken.
In conda I noticed my current version of Jedi was out of date, and I upgraded to the newest version. In the process I noticed that conda said it needed to downgrade Spyder for the Jedi upgrade. This gives me the impression that Spyder 4 just doesn't support Jedi. Is that the case?
