问题
I have to handle sparse matrix that can occasionally be very big, nearing or exceeding RAM capacity. I also need to support mat*vec and mat*mat operations.
Since internally a csr_matrix is 3 arrays data, indices and indptr is it possible to create a csr matrix from numpy memmap.

This works without any problems.
