Issues with editing labels after training on Ubuntu/Linux

[jljavie]

Hi SLEAP team!

I am new to SLEAP and just downloaded it in a conda environment using pip to protect other dependencies on the computer. I am using SLEAP 1.5.2 and I am able to load a video, save, add my initial labels and run training. However, after training when I have to edit the predictions SLEAP keeps crashing. My computer says it is taking too long to respond. I checked to see if anything was being overloaded and it seems not. It uses the GPUs successfully and I have ran DLC on this computer so I don't think it is running out of memory/etc.

If I close and relaunch, I can open the project with the skeletons and predictions but as soon as I click in the GUI, SLEAP goes unresponsive. Any idea on what I could do to troubleshoot? Should I just reinstall?

SLEAP: 1.5.2
Numpy: 2.26
Python: 3.13.9
OS: Linux-5.15.0-161-generic-x86_64-with-glibc2.35 (Ubuntu 22.04.5 LTS)

UPDATE:
Just as an update. I have now updated Ubuntu, updated all nvidia drivers, deleted my old environment, made a new one and reinstalled SLEAP with pip again. Still having SLEAP become unresponsive when I try to correct labeled frames.

Software versions:
SLEAP: 1.5.2
Numpy: 2.2.6
Python: 3.13.9
OS: Linux-6.8.0-87-generic-x86_64-with-glibc2.39
