Bug description

Difficulty installing 1.5.1 on Arizona State University computer cluster.

Actual behaviour

Error: Could not load the Qt platform plugin "xcb" in "datalocation/python3.13/site-packages/cv2/qt/plugins" even though it was found.

We are currently using 1.4.1a2, which had no difficulty installing on the server.

Hi @verpeutlab !

Could you let us know how you installed sleap 1.5.1?

Thanks,

Divya

Hello! Thanks to our latest refactor, you are now able to use https://github.com/talmolab/sleap-nn --the backend of SLEAP--without having to install frontend dependencies like Qt.

What are you trying to do on the cluster? Thanks!
