Issue 1:
Hello all

This morning I downloaded numba as well as updated all packages with conda update --all. I get an error when trying to import numpy. The message in the ipython console prompted me to post on Github. The exact error message is:

Original error was: DLL load failed: The specified module could not be found.

Some notes about my Anaconda/spyder environment

Both python and numpy were updated with the updates this morning

I am working on windows 10

I have had other python interpreters for awhile now. The other one is used in an ubuntu on windows virtual machine. But I did check to make sure the path to site-packages was correct in spyder.

I have seen similar posts from 2 days ago but I couldn't find any solutions that worked for me.

Thanks in advance

In the console of VSCode:

activate python37

pip install numpy

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

All advices, reinstallations via pip and conda, or different numpy versions (e.g. 1.15.4) didn't solve this issue for me.

If I do multiple pip uninstall numpy until there is no numpy left, and then do a conda install numpy, importing numpy interestingly works (in 1.15.4).

A conda install numpy does the following:

The following NEW packages will be INSTALLED:

icc_rt pkgs/main/win-64::icc_rt-2019.0.0-h0cc432a_1

numpy-base pkgs/main/win-64::numpy-base-1.15.4-py37hc3f5095_0

What's missing for the pip way?

Any ideas?
