2D Error- Nan problem

Dear Cryosparc developer,

I am new to the cryosparc. Below is the error message, while running the 2D classification. Could you please help.
I am using the latest version 4.6.

Traceback (most recent call last):
File “/home/cryosparc_user/software/cryosparc/cryosparc_worker/cryosparc_compute/jobs/runcommon.py”, line 2304, in run_with_except_hook

I tried running the following command.
cryosparcm eventlog pxx jxxx | tail n -30

Welcome to the forum @Akmp .

Please can you send the failed job’s error report to us.

I will let you know a suitable email address via a private message.

Thanks @wtempel

I sent you an email.

Error report received. Thanks.

Hello, I have encountered the same problem. How did you solve it?

Hi,

I am waiting for the reply from the cryosparc team.
