Hi @guolu,
The following error might be caused by running the installation as the root user. It’s possible that running these commands as root uses the system’s python and not the Anaconda python that we’ve included in our dependency bundle. Is it possible if you can remove this installation (simply delete cryosparc2_master and cryosparc2_worker folders) and reinstall as the cryosparc_user account?
Also, the error quoted below may indicate another cryosparc process was running before you started the installation. Please follow steps to ensure any other cryosparc processes are terminated before running an installation/update.
