Note that we're encouraging people to migrate to CuPy, which provides wrappers around the same CUDA libraries that pyculib provided, but with a nicer NumPy interface.
@seibert CuPy has limited capability for writing Kernels in python. Numba cuda device arrays supposedly works with pyculib functions, so it is better suited for python use.

i have the same question,but in cupy there is still a question for me ,i need to use BSR_matrix,it can only be used by pyculib not in cupy
