Cryosparc unable to run any 2D or 3D job

Troubleshooting

Recently I also encountered this problem. I solved it by modifying the code in compile.py as shown in the last line of the error (mine was in /cryosparc_worker/deps/anaconda/envs/cryosparc_worker_env/lib/python3.7/site-packages/pycuda):

class SourceModule(CudaModule):
    '''
    Creates a Module from a single .cu source object linked against the
    static CUDA runtime.
    '''
    def __init__(self, source, nvcc="nvcc", options=None, keep=False,
            no_extern_c=False, arch=None, code=None, cache_dir=None,
            include_dirs=[]):
        self._check_arch(arch)

        cubin = compile(source, nvcc, options, keep, no_extern_c,
                arch, code, cache_dir, include_dirs)

        from pycuda.driver import module_from_buffer
        self.module = module_from_buffer(cubin)

        self._bind_module()

Upon googling, it seems that the arch parameter would cause error. So I simply removed it:

class SourceModule(CudaModule):
    '''
    Creates a Module from a single .cu source object linked against the
    static CUDA runtime.
    '''
    def __init__(self, source, nvcc="nvcc", options=None, keep=False,
            no_extern_c=False, code=None, cache_dir=None,
            include_dirs=[]):
        #self._check_arch(arch)

        cubin = compile(source, nvcc, options, keep, no_extern_c,
                code, cache_dir, include_dirs)

        from pycuda.driver import module_from_buffer
        self.module = module_from_buffer(cubin)

        self._bind_module()

And 2D class and 3D ab initio can be run again!
