When computing sparse matrix matrix product between two CSR sparse matrices with function torch.sparse.mm on PyTorch version 1.10.0+cu102, I am getting the following error: NotImplementedError: Could not run 'aten::empty.memory_format' with arguments from the 'SparseCsrCUDA' backend. This could...
At the matrix multiplication with scipy.sparse.csc_matrix matrices, nan * 0 results in 0 and not in nan as in the dense case. Look at this short example: A = scipy.sparse.csc_matrix([[np.nan, 1], [2, 3]]) B = scipy.sparse.csc_matrix([[0, 0], [0, 1]]) Here (A @ ...
