Encountering error during import movies job

Troubleshooting
1

Hello Cryosparc developers,

I recently installed cryosparc v2.15.0 on a brand new work station and I am encountering a message that says “list index out of range” when trying to import movies and my job just remains on “Queued” and never actually runs. Any idea why this might be happening?

Thanks,
Brian

Hi @Brian,

Sorry for the delayed response, and sorry to hear you’re having trouble running jobs. The error you posted suggests that there isn’t a worker node for cryoSPARC to run jobs on. You can configure this by following our guide: https://guide.cryosparc.com/setup-configuration-and-management/how-to-download-install-and-configure/downloading-and-installing-cryosparc#connecting-a-worker-node-or-cluster-workload-manager

Once you have set up at least one machine (or cluster) capable of running jobs, you should be able to queue and run the job no problem!

Please let me know how things go.

Hi @sdawood,

I am attempting to follow the guide that you set to connect a worker node, but I have been running into an error when I type the commands into the terminal. I don’t think it likes my input for the master hostname. Is there a way I can identify the name of the server where the master was installed? I have posted the error messages I have been receiving below.

HTTPConnectionPool(host=‘brian.cryosparc.hostname.com’, port=39002): Max retries exceeded with url: /api (Caused by NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x7f8448a1d990>: Failed to establish a new connection: [Errno -2] Name or service not known’,))

Hi @Brian,

If you’re running on CentOS 7, you may want to double check the built-in firewall: you might have to add port 39000 to the allowed ports. Take a look at this post here: https://stackoverflow.com/questions/24729024/open-firewall-port-on-centos-7 and our guide for the list of ports: https://guide.cryosparc.com/setup-configuration-and-management/cryosparc-installation-prerequisites#4-open-tcp-ports

Hi @sdawood,

I was able to successfully connect the worker node and my import movies job now runs successfully. However, when I attempt to run patch motion correction (multi) the job status says “queued” and “CPU unavailable”. Any idea why this might be happening? This work station has 16 cores, 192 GB RAM, and 4 gpus. Thank you for all your help!
