While numpy/scipy wheels are available, run python3.8 test without them
|
To make CI of this PR meaningful I added python3.8 to CI matrix. Unfortunately numpy and scipy wheels are not available for python3.8. As a result pip tries to install them the from source and hits 30 seconds time limit of Therefore I think for the moment it would be ok to run test python3.8 on CI without numpy/scipy. In addition I've checked tests locally with numpy and scipy. |

Super-cool -- thank you very much for tracking down the issue and fixing it. |

Note: This patch leads to segfault in python 3.8.0b4 (and I guess in earlier 3.8.0* versions too). Update to 3.8.0rc1 solves the problem. |
