Topaz 0.2.5, v3.2.0 - NotImplementedError: can't find current frequency file


After upgrading to 3.2.0, I’m experiencing to execute the topaz extract job with the following reproducible error at the early stage of Preprocessing stage.

========= monitor process now starting main process
MAIN PID 42032
Traceback (most recent call last):

If anyone has any suggestions to look into, it would be very much appreciated.

Hi @heejongkim,

Can you report your OS/Kernel version: uname -a


It’s Centos 7and here’s the output of “uname -a” output.
Linux kingcobra 3.10.0-514.2.2.el7.x86_64 #1 SMP Tue Dec 6 23:06:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux


Hi @heejongkim,

Looking at this error message again, it looks like your cluster scheduler killed this job because it used too much RAM.
If you’re still having this error, edit the last line in the file cryosparc_master/cryosparc_compute/jobs/topaz/
job.set_resources_needed(cpu_count, gpu_count, 8000, False) to
job.set_resources_needed(cpu_count, gpu_count, 16000, False)
then run cryosparcm cli "refresh_job_types()", create a new Topaz Extract job, and run it.
