installation of numpy inside the shell using conda

Question

For some reason I get the error message:

During initialization the error Something is wrong with the numpy installation. While importing we detected an older version of numpy in ['C:\Program Files\FreeCAD 0.18\bin\lib\site-packages\numpy']. One method of fixing this is to repeatedly uninstall numpy until none is found, then reinstall this version. occurred in C:\Users\foobar\AppData\Roaming\FreeCAD\Mod\A2plus\InitGui.py Please look into the log file for further information

whenever I run FreeCAD on a specific computer. Now I could use any of these solutions to install packages using pip inside Python console (Python REPL shell), except the new FreeCAD uses conda. This post suggests installing numpy by downloading and unarchiving the zip file which I think is a bad idea. My environment is:

OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.16131 (Git)
Build type: Release
Branch: releases/FreeCAD-0-18
Hash: 3129ae4296e40ed20e7b3d460b86e6969acbe1c3
Python version: 3.6.6
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)

I would appreciate it if you could help me know what is the problem and how I can solve it. Thanks in advance.

"new FreeCAD uses conda" is the "new" version the "FreeCAD 0.18" one or is that the old version. Anyway, try using `pip uninstall numpy` before `conda install numpy` — FlyingTeller, Oct 28 '19 at 09:27
@FlyingTeller I'm not sure since when FreeCAd uses conda instead of pip, so I can't comment on that. sure I would do `pip ...` or `conda ...` if there was a way to communicate with embedded pip/conda inside FreeCAD. — Foad S. Farimani, Oct 28 '19 at 09:49
@FlyingTeller yes there is. can I run `python -m pip ...` or `python -m conda ...` inside that folder with that executable? — Foad S. Farimani, Oct 28 '19 at 12:24
probably not `python -m conda`, but you could try `python -m pip uninstall numpy` and then try installing `numpy` again — FlyingTeller, Oct 28 '19 at 12:28
@FlyingTeller but how can I install numpy after uninstalling? — Foad S. Farimani, Oct 28 '19 at 13:40
What did you try when you created the error message that is in your question? — FlyingTeller, Oct 28 '19 at 15:47
I searched the internet for a similar error message, posted a bug report on the A2plus repository, uninstalled and reinstalled FreeCAD. — Foad S. Farimani, Oct 28 '19 at 19:30
