(Py3.10) Error on loading: TypeError: TypeChecker() takes no arguments

[sanjayankur31]

Hello,

I upgraded to Fedora 35 (to be released soon, in beta now) to get to Python 3.10 since the bug in Python 3.9 prevents me from using weeslack and weechat-matrix together (https://github.com/wee-slack/wee-slack/issues/812). However, on this newly upgrade system, I'm running into these errors on loading the script:

I can run the import command just fine in python:

from nio import RemoteProtocolError, RemoteTransportError, TransportType
# all good, no errors here

So maybe it's something related to my upgrade (some pyc or __pycache__ files still referring to older versions or something) but I can't figure out how to go about debugging this. Any hints please?

I've just come across the same issue. Void Linux just recently upgraded to python 3.10.0 and I can't feasibly downgrade back to 3.9. Using a virtualenv doesn't work either due to incompatibilities between versions.

I'm also at a loss of what it could be. I don't think it's due to any .pyc files, cleared any cache I could find and it didn't change anything.

+1 - same issue as the description. On Fedora 35, with python 3.10.0

I've tried python 3.9, 3.7 and 2.7, they all give me different errors when trying to load matrix.py in weechat.

[thatnerdjosh]

I spent many hours today looking into this without much success :(... however I did make a docker image and summary of what I found in case anyone wants an easy way to reproduce it

[yalla]

Having the same problem and can't seem to find any way around it. Suggestions?

[hroncok]

I believe this is a bug in Python subinterpreters: https://bugs.python.org/issue46034

[diabonas]

I confirm that applying cmp_interned_strings.patch attached to the upstream Python issue bpo-46006 on top of Python 3.10.1 fixes the issue when trying to load the weechat-matrix script.

[Zapeth]

I no longer get this error with python 3.10.2 (void linux)
