Hi @yurivict. I might be missing something, but I don't see anything about which tests failed in the output you've provided. The "invalid value encountered in reciprocal" warnings are concerning but I can't tell whether these are related to any test failures. Is there any extra output showing which tests failed? It might help to run pytest with the -v option to get more verbose output.

Can you also please specify which version of numpy you are using
