Problem importing (and installing) NumPy in Jupyter Notebook
In my case, inside Jupyter notebook, you need to change Kernel (Anaconda environment). I thought you changed environment using conda activate myEnv, but when launching Jupyter, it defaults to the root environment.
I hope this is in fact true- I am a noob in Anaconda.
I am having major trouble right now trying to use numpy in my jupyter notebook.
When I first tried to simply "import numpy", it came back with the error: "ModuleNotFoundError: No module named 'numpy'"
I then read somewhere that I probably needed to install numpy. 
So I did this: "import sys
!conda install --yes --prefix {sys.prefix} numpy"
to which it came back saying: "EnvironmentLocationNotFound: Not a conda environment"
Now when it comes to understanding environments or packages or ANYTHING along those lines, I just have no idea what I'm doing. I am in a very beginner course and just following along. 
I wish I could understand all of this environment and versioning stuff. 
I have no idea where to go from here.
Any insight here would be GREATLY appreciated!!
Edit: I am in fact using Anaconda to launch Jupyter Notebook. Not sure if that means anything to your understanding of my problem or a potential solution.
