I am encountering an error while performing 2D classification on manually selected particles. Could you please help me troubleshoot and resolve the issue?

Please can you post the output of the
command (on the CryoSPARC master computer)

cryosparcm cli "get_scheduler_targets()"

and of the commands (on the CryoSPARC worker computer, may or may not be the same as master) where the job ran:

uname -a 
nvidia-smi
/home/dawson/cryosparc_worker/bin/cryosparcw gpulist

Thank you, Wtempel. The issue was indeed caused by the improper installation of the NVIDIA driver. I truly appreciate your prompt and helpful response.
