So for some reason python module inside conda environment was compiled with system library (libstdc++.so.6.0.30) instead of conda one. The second option is more viable, as libstdc++.so.6.0.26 provided with conda environment does not have “ZSt28” symbol, while my system library has. Which might suggest bad cuda install or python 3.7 compiles badly _driver.cpython-37m-x86_64-linux-gnu.so against libstdc++.so.6. > ImportError: /opt/cryosparc2/cryosparc_worker/deps/anaconda/envs/cryosparc_worker_env/lib/python3.7/site-packages/pycuda/_driver.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZSt28_throw_bad_array_new_lengthv But during the worker connect attempt, one gets: If we ignore the missing nvidia-smi program and go with the installation, master and worker install seemingly ok.The option might be to install driver and toolkit from nvidia repository, but this is officially not recommended by ubuntu. usr/local/cuda) and symlink cuda dirs (bin, lib64.include, share) Thus, during master/worker installation one cannot give a single cuda-path parameter, unless one manually create fake directory (ie. They’re not placed in any /usr/local/cuda directory. But the toolkit install removes nvidia-utils package together with nvidia-smi command! Utils reinstall on the other hand removes toolkit!Īlso, ubuntu nvidia-cuda-toolkit package spreads cuda libraries and binaries into /usr/bin, /usr/lib/x86_64-linux-gnu and so on. This installs 515 recommended driver and utils, and then cuda toolkit 11.5.
Preferred nvidia driver (with nvidia-utils and nvidis-smi) and cuda toolkit installation process is via ubuntu repositories: However, I have checked creatings a symlink to cryosparc_worker which seems to be ok. One, probably should not blindly configure this directory as worker during master install. But, the cryosparc2_worker directory has only version file. Recent cryosparc_worker package is shipped with 2 worker directories: cryosparsc2_worker and cryosparc_worker. While trying to cryosparc standalone on single desktop on still unsupported Ubuntu 22.04 LTS desktop I have encountered 3 problems:
