How to change the path where Jupyter looks for libraries

I have python 3.10 installed on disk C: and Anaconda with Python 3.9 on disk D:. When I try importing numpy in jupyter, I get the following error.
>>> import numpy

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "D:\ProgramData\Anaconda3\python.exe"
* The NumPy version is: "1.23.3"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'
Looks like Python interpreter from disk D: is looking for libraries in disk C:, and I suppose that the numpy file installed there is not compatible with python 3.9. I think it's because my PYTHONPATH is
>>> print("PYTHONPATH:", os.environ.get('PYTHONPATH'))
PYTHONPATH: C:\Python310\Lib\site-packages
But how do I change it so that Jupyter only looks for what's in Anaconda folder libraries and not break whatever I have on disk C:? I guess what I'm asking is, is it possible to have 2 PYTHONPATHs, one for Jupyter and one for whatever else? Would it be sufficient to just add Anaconda libraries folder to PYTHONPATH, or it would cause conflicts? Because how would Jupyter choose one path over the other?

Ursina.build can't find modules?

I was reading This, when it said I was supposed to use the command python -m ursina.build to compile my project. When I launched the .bat file I got this error
package_folder: C:\Users\sbahr\OneDrive\Documents\programming\Python\MeshGame\build\python\lib\site-packages\ursina

import numpy as np
ModuleNotFoundError: No module named 'numpy'
I ran pip install numpy and it said numpy was already installed.

This used to be automatic, but broke in a newer version of Python. Therefore you'll have to provide a list of extra modules to copy, if you're using any.
From ursina's documentation (https://www.ursinaengine.org/building.html):
Make sure to include any extra modules with --include_modules PIL,numpy for example.

Importing the numpy C-extensions failed on mac

I have a problem with importing NumPy and pandas, already installed all the packages but trying to import them but getting the below error,
I also tried to uninstall and reinstall the packages again but didn't work.
here is the pip lists:
I also tried conda but couldn't solve the problem.
Btw: I am using Mac pro and atom.

Error importing numpy even though I installed it properly

I am using a module called investpy, and numpy is a dependency of it. I tried running pip install investpy, which installed all of the dependencies (or so it says). However, when I try running
import numpy
or
import investpy
, I am faced with this error:
Traceback (most recent call last):

raise ImportError(msg)
ImportError: Error importing numpy: you should not try to import numpy from
its source directory; please exit the numpy source tree, and relaunch
your python interpreter from there.
I'm really confused as to why this is happening, because as far as I know, I correctly installed numpy. Furthermore, this is really weird because, if I go to the python directory in cmd and run import numpy, it works perfectly.
Any help would be greatly appreciated. Thank you!

Essentially numpy seems to complain that it isn't being imported from a standard path.
It looks like you installed numpy directly into your project directory under C:\Users\kakor\OneDrive\Desktop\ML\numpy You should remove that directory and try running
pip install numpy

How do I know which .dll is missing in python with cx_freeze?

I have a project which I am packaging with cx_freeze. When I try to run the resulting exe I get an ImportError: DLL load failed: The specified module could not be found.
Here is my setup.py:
from cx_Freeze import setup, Executable
# Dependencies are automatically detected, but it might need
# fine tuning.
buildOptions = dict(build_exe='liquidation', packages=['scipy', 'numpy'], excludes=['scipy.spatial.cKDTree'],

When I run python setup.py build_exe it seems to complete successfully, but when I run the exe I get the following output:

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 "C:\Users\tamar\PycharmProjects\liquidation\liquidation\liquidation.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.3" 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, try `git 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: DLL load failed: The specified module could not be found.
I understand that I need to point cx_freeze to the missing DLL's (either by adding them to buildOptions.include_files or by actually copying the DLL's to the build folder) but I am at a loss as to how to know which DLL's I am missing. numpy.core._multiarray_umath is in the build folder so I don't know what it could be.
I believe I am using the latest versions of numpy (1.18.3), scipy (1.4.1) and cx-freeze (6.1). Any help would be much appreciated!
Update: I used Dependency Walker to try and see what I am missing and it listed a file by the name of LIBOPENBLAS.SVHFG5YE3RK3Z27NVFUDAPL2O3W6IMXW.GFORTRAN-WIN32.DLL which cannot be found. All of the other dependencies have been copied into the build so it makes sense that this would be the missing one. Does anyone know where I can find this file?
