Error importing numpy after pip install intel-numpy

On Windows 10, I installed 64-bit Python 3.6.8 from python.org, then installed numpy with "pip install -U intel-numpy".

Then when importing numpy I get the below error. Please advise on the fix.

 

Thanks!

 

>> python -c "import numpy"
Traceback (most recent call last):

    from . import multiarray

During handling of the above exception, another exception occurred:

ImportError:
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

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

This is a common problem if you install versions with intermixed pip and numpy dependencies in an environment.  Can you post your conda list and conda info output for us to look at?

I'm not using Anaconda. This is a clean install of python from the python.org binaries, and intel-numpy is the first and only package installed.

Pip has not collected one of the dependencies right then.  You'll need to remove the packages from /site-packages/numpy/ and try to reinstall NumPy.  Multiarray is a common failure in NumPy if the installation fails to install correctly.
