Hi All,

I searched the following error but no solution so I posted it as a separate topic. Any suggestion? Thanks.

Dear @donghuachen, can you please see if this post helps? 3DVar must not contain infs or NaN

@spunjani, Thanks. I am re-running the same job with another GPU on the same computer.

@spunjani, I re-run the same job on another GPU of the same computer and succeeded.

Hi,
I am receiving the same exact error on iteration 6 of 20. @donghuachen said they were able to use a different GPU and it worked. I also tried this and was still met with the same problem. What would cause this error? I have ran many 3D var jobs and never had this issue before.

Thanks,
Karl

@kherbine Please can you post the output of this command (replacing P99 and J123 with the job’s actual project and job IDs):

cryosparcm cli "get_job('P99', 'J123', 'job_type', 'version', 'params_spec', 'input_slot_groups')"

Hi @wtempel,

I actually came across another thread and increased Lambda from 0.01 to 0.02 and that fixed my issue and the job ran to completion. However, here is the output:
