[gentoo-user] Problems with numpy and python 3x

Hi,

after the update this morning, "numpy" wasn't found anumore by python.

Asking python, it gave me:
Python 3.7.5 (default, Dec 15 2019, 05:23:14) 
[GCC 9.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'numpy'
>>>

eix numpy gave me:


[U] dev-python/numpy
     Available versions:  1.14.5^t (~)1.15.4^t (~)1.16.1^t (~)1.16.5^t (~)1.17.4^t {doc lapack test PYTHON_TARGETS="python2_7 python3_5 python3_6 python3_7 python3_8"}
     Installed versions:  1.16.5^t(06:31:45 AM 12/15/2019)(lapack -doc -test PYTHON_TARGETS="python2_7 python3_6 -python3_5 -python3_7")
     Homepage:            https://www.numpy.org
     Description:         Fast array and numerical python library


emergeing it with

emerge --selective=n dev-python/numpy

results in the same output of eix.

Interestingly a post on stackexchange related to the problem of "numpy
not found" states (source: https://stackoverflow.com/questions/7818811/import-error-no-module-named-numpy_)

"Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy."

and links to this address: https://sourceforge.net/projects/numpy/files//NumPy/1.5.0/NOTES.txt/view
which states the same.

A version of numpy >= 1.5 is not offered by portage repo it seems, but
python 3.x is.

pip3 says, everything is fine, numpy is installed:

pip3 install --user numpy
Requirement already satisfied: numpy in /usr/lib64/python3.6/site-packages (1.16.5)

But this does not fit the installed python version according to the
linked sources above.

How can I solve this problem?

(I am on "unstable"...)

Cheers!
