f93ffc9e - Sparse CSR: Handle zero matrix consistently for triangular_solve (#71304)

Sparse CSR: Handle zero matrix consistently for triangular_solve (#71304) Summary: This PR enables `test_block_triangular` tests on the CPU. These tests revealed that there was a problem with how the nnz==0 case is handled. Now we return a tensor filled with NaNs both on CUDA and CPU. cc nikitaved pearu cpuhrsch Pull Request resolved: https://github.com/pytorch/pytorch/pull/71304 Reviewed By: davidberard98 Differential Revision: D33600482 Pulled By: cpuhrsch fbshipit-source-id: d09cb619f8b6e54b9f07eb16765ad1c183c42487
