numpy is installed but I got the error "DLL load failed while importing _multiarray_umath: The specified module could not be found."

Question

I am using the Anaconda distribution with Python 3.9. Among the packages installed, I have numpy, pandas, etc. In PyCharm IDE, I have set the Project Interpreter to be the path to the python.exe installed with Anaconda: C:\Users\[user]\anaconda3\envs[Tensorflow]\pythonw.exe

P.S: I have tried every method to fix this problem on stack overflow from including more paths to uninstall and reinstall but none of those work. Please help!

C:\Users\nguye\anaconda3\envs\[Tensorflow]\pythonw.exe C:/Users/nguye/PycharmProjects/tensorEnv/main.py

During handling of the above exception, another exception occurred:

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:

Please note and check the following:

  * The Python version is: Python3.9 from "C:\Users\nguye\anaconda3\envs\[Tensorflow]\pythonw.exe"
  * The NumPy version is: "1.22.2"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

I faced same issue and fixed it by adding the following variables to system environment PATH:

C:\Users\[username]\anaconda3
C:\Users\[username]\anaconda3\Scripts
C:\Users\[username]\anaconda3\Library\bin
