Master Worker version mismatch after update to v3.3.1

We updated CS v3.2.0 to v3.3.1. The update went well. But with the new version of CS it gave an error of Master Worker version mismatch as shown below:

File “cryosparc_worker/cryosparc_compute/”, line 46, in
AssertionError: Version mismatch! Worker version (v3.2.0+211012) and Master version (v3.3.1) are not the same. Please update.

We updated again but it did not resolve the problem. Please advise how to fix it without loss of current processed data. Thank you in advance!

You need to manually update the worker. See here and related threads:


Hi Oli, Thanks for your response. As you suggested I run ./bin/cryosparcw update --override in the directory of cryosparc2_worker. The command returned an error “cryosparc_worker.tar.gz is missing” even though the file cryosparc_worker.tar.gz is present. Any suggestions would be appreciated.

@haomingz Is cryosparc_worker.tar.gz in fact present in the worker’s installation directory, as described in the guide?

Thanks for your response. yes it’s in the worker installation directory. Somehow the command “cryosparcw update --override” didn’t find it so that I couldn’t update the worker node. I would appreciate your help to fix it.

@haomingz Inside the worker’s installation directory, what output does the following command produce?
ls -l && ls -l bin

Here are the outputs:

try changing the name of cryosparc2_worker.tar.gz to cryosparc_worker.tar.gz

@haomingz Two concerns:

  1. cryosparc2_worker.tar.gz is dated July 28, 2020. Could this file belong an older version of cryoSPARC?
  2. The guide suggests that the (correct) cryosparc2_worker.tar.gz or cryosparc_worker.tar.gz should be placed (a valid link might work) inside /app/apps/rhel7/cryosparc/cryosparc2_worker/.

Thanks for pointing us to the right direction. The problem has been fixed. We very much appreciate your help.
