RuntimeWarning: invalid value encountered in true_divide

Hi,

I am facing a recurrent problem of jobs ending with “job process terminated abnormally”. Below is a log file for more details. I get this error with different data sets and parameters and it happens at different stages of running jobs. I added CRYOSPARC_NO_PAGELOCK=true to worker config but didn’t help. It mainly happens at 2D but also in Ab-initio.
I have a workstation with 4 RTX 2080 Ti, 24 CPUs, Centos 7, box size: 90-360
I was wondering if there is a fix for it? or it’s related to the computational setup?
Thanks,
Yashar
