Embedded Python - Errors with Numpy

When I install the numpy package on Python on my PC using:

pip install numpy

I can use it in python on my machine. If I do:

pip install --target C:\InterSystems\IRIS\mgr\python numpy

I get errors any time I try to import it in embedded python.

Traceback (most recent call last):

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 "c:\intersystems\iris\bin\IRISDB.EXE"
  * The NumPy version is: "2.1.2"
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'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "c:\intersystems\iris\mgr\python\numpy\__init__.py", line 133, in <module>
    raise ImportError(msg) from e
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.

Has anyone else run into this and do you know how to fix it?
