NumPy not available?

[snippsat]

his morning, I installed Anaconda3 (thinking maybe this could solve the problem).

You most activate (base) eg trough Anaconda Prompt
Long Thread here where talk about Anaconda and versions from python.org

For version from python.org
Python 3.8 (3.6-3.7) and pip installation under Windows

Anaconda3 do of course comes with numpy,here manual activate of base.

G:\Anaconda3\Scripts
λ activate

# See (base)
(base) G:\Anaconda3\Scripts
λ pip -V
pip 20.0.2 from G:\Anaconda3\lib\site-packages\pip (python 3.7)

# conda most know about,the pip of Anaconda
(base) G:\Anaconda3\Scripts
λ conda -V
conda 4.8.3

(base) G:\Anaconda3\Scripts
λ python
