Numpy can't be imported in Spyder
Problem did not occur again after re-installing Anaconda. Thanks @CarlosCordoba.
When trying to import numpy in spyder i get the following error message:
ImportError:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "/home/sltzgs/anaconda3/bin/python",and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy version "1.17.2" you're trying to use.
2. If (1) looks fine, you can open a new issue at
     https://github.com/numpy/numpy/issues.  Please include details on:
     - how you installed Python
     - how you installed numpy
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, trygit clean -xdf(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: No module named 'numpy.core._multiarray_umath'
However, importing in a jupyter notebook works fine. How is that possible? 
I have uninstalled/installed numpy a few times by now and also made sure, that the sys.paths are identical.
Any help appreciated. In case any additional information is required I would happily help out. Thanks.
Some essentials:
python 3.7
Spyder 3.3.6 
numpy 1.17.2
