Memory error during 2Dclassification

2D Classification

Hi All,

I am using cryosparc 3.2.0 and spontaneously see following error during 2D classification. Any help will be appreciated.

File"/home/cryosparc_user/software/cryosparc/cryosparc_worker/cryosparc_compute/jobs/runcommon.py", line 1790, in run_with_except_hook
run_old(*args, **kw)

Hi @Anamika, are you running cryoSPARC on CentOS7?
If so, please try the instructions available here which may help: CUDA memory error during 2D classification
Thanks!
