Scipy: Can't import scipy

[leynier]

My issue is about the import of scipy

Reproducing code example:

import scipy

Error message:

This looks like a failed install or incomplete build. Not much more we can say without a build log.

Not a SciPy issue, so closing. If you still have trouble @leynier please feel free to continue the discussion. We need more details on your install method in that case.

I solved the problem by installing Python 3.6 and installing Scipy in that version. Because with version 3.7 the problem continued even if I reinstalled Scipy. The installation method I use is pip.

I just met the same issue, thanks to leynier, I updated python to 3.8 and problem solved.
