PyCuda mem_alloc initialization error

Question

in desaturate_image
    redarray_gpu = cuda.mem_alloc(self.redarray.nbytes)
pycuda._driver.LogicError: cuMemAlloc failed: initialization error

I get the above error on this line:

redarray_gpu = cuda.mem_alloc(self.redarray.nbytes)

What could be the reason?

Answer 1

import pycuda.autoinit

This import statement fixed the issue. My best guess is that the device was not initialized
