Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Missing hypothesis as a test dependency:

    import hypothesis
E   ModuleNotFoundError: No module named 'hypothesis'

ERROR  - ModuleNotFoundError: No module named 'hypothesis'

Do we know if this is still needed, @isuruf?

@jakirkham: Do we know if this is still needed, @isuruf?

Based on the results of trying to remove it in #196, I'd say that it's not needed anymore (i.e. ppc64le builds & tests run through without this on both netlib & openblas)

[mattip]

I would strongly recommend updating openblas to 0.3.10. NumPy released 0.19 with a slightly older commit since 0.3.10 came out too late in the release cycle to update. The latest version fixes some bugs for other architectures and also no longer segfaults with PyPy on linux64

[jakirkham]

Yeah I think that is what @h-vetinari is trying in PR ( #196 ). Though we are seeing some failures as noted in comment ( #196 (comment) ).

[h-vetinari]

@conda-forge-admin, please restart ci

[mattip]

Why do the ppc64le runs show numpy1.16? Is that just an artifact or is that really the version?

[mattip]

@isuruf any ideas how to move forward on getting numpy 1.19 onto conda-forge?

[isuruf]

There's something wrong with the openmp version of openblas. Switching the default to the pthreads version fixed it.
