This fix appears to work for us as well on a CentOS system.
Reference:
I did have to first revert the system:
./bin/cryosparcw forcedeps
Then edit cryosparcw and change from:
conda install -y cuda-nvcc=11.7 cuda-toolkit=11.7 -c nvidia
To:
conda install -y cuda-nvcc=11.7 cuda-toolkit=11.7 -c nvidia/label/cuda-11.7.0
Then finally run the 3dflex installer:
./bin/cryosparcw install-3dflex
No more lengthy errors, and users report that jobs appear ok so far.
