Hi @Bruk,
I can help you out with a few things:
Yes, you can uninstall cryosparc2_worker by deleting the directory. Also, what @apunjani meant by “point it to an older CUDA version” is specify a different CUDA path in the args for the cryosparc2_worker install script.
./install.sh --license $LICENSE_ID --cudapath /usr/local/older-cuda
Also, cryosparc2_master doesn’t need to know about the CUDA path, so there will be no problems with downgrading.
