A server errors appears as I interact with the server

[manueldeljesus]

I am using Emacs 28.1 on Fedora 36 with Doom Emacs distribution. I am trying to use anaconda-mode in a very simple python file (importing numpy and trying to use linspace). As I am halfway writing the function name I try to autocomplete and the following error appears:

Any idea on how to debug the problem further or how to solve it?

Any help will be much appreciated

This is a bug with jedi and the latest numpy. See https://github.com/davidhalter/jedi/issues/1864

Should automatically be fixed once there is a new jedi version. If you want to patch it manually earlier, I guess you can go to anaconda-mode-installation-directory and update/patch the jedi version installed in this virtualenv.

Thank you very much for the answer.

I was testing anaconda-mode and starting with numpy. I assumed that it was not going to work for any other python library, but didn't test it.

I'll wait for jedi to update.
