Complete the installation and run /script load matrix.py, I got the following error. What should I do?

Well, seems like OpenSSL started to use Rust and PyO3 for their Python bindings. And you seem to be loading multiple WeeChat Python scripts which use OpenSSL, which PyO3 doesn't seem to support.

I'm not sure that there's much we can do.

I have similar error and cannot load matrix.py. This is being tracked in pyo3 at PyO3/pyo3#576

My error is:

Getting the same traceback on a mostly fresh install on Ubuntu 22.04 in WSL (Python 3.10.12) (Same error on Ubuntu 24.04 LTS/Python 3.12.3)

I am also having this problem – does anyone know how I would find out whether I am

loading multiple WeeChat Python scripts which use OpenSSL

?

Because of the few Python scripts in the list of loaded scripts, none are particularly networky or anything beyond things like topicdiff, auto_away, etc.

Oooh wait, I'm dumb. I get a separate error when I first load the plugin, then when I reload it I get this error because it conflicts with itself – or something?

Hi @poljar So is this basically the question if Py03 starts supporting openssl or they don't? Or as well, if pyOpenSSL starts including another package than Py03? I'm just trying to understand the changes that were made and who made them upstream.. Or I guess if you support and include a different openssl package then pyOpenSSL in your code? Thanks for any insight..

On the README for pyOpenSSL it says Note: The Python Cryptographic Authority strongly suggests the use of [pyca/cryptography](https://github.com/pyca/cryptography) where possible. If you are using pyOpenSSL for anything other than making a TLS connection you should move to cryptography and drop your pyOpenSSL dependency.
