Cryosparc Standalone install Cuda Error


I am running Cryosparc v3.1 on a Ubuntu machine. While running the test dataset, I keep running into this error:

I have installed cuda 11.0 with driver version 460.32

'worker_bin_path': '/opt/cryosparc/cryosparc_worker/bin/cryosparcw'}}

OSError: CUDA driver library not found

Hi @achintangal, can you please see the solution here and see if that works for you? Raise OSError('CUDA driver library not found')

And also: IOError: [Errno 32] Broken pipe

Thanks! That fixed the problem!
Must be something new with Cuda 11.x.
