I am creating a new environment using anaconda in windows with some packages

conda create -n myenv
conda activate myenv

conda install python
conda install cvxopt
conda install gym
conda install networkx
conda install pandas
conda install matplotlib

It installed the following versions:

python-3.9.2
cvxopt-1.2.6
gym-0.18.0
networkx-2.5
pandas-1.2.3
matplotlib-3.3.4

When I try to run any simple code that import numpy: I am getting the following error:

Traceback (most recent call last):
  File "C:\Users\kkris\anaconda3\envs\cbf_gym\lib\site-packages\numpy\core\__init__.py", line 22, in <module>

    from numpy.core._multiarray_umath import (
ImportError: DLL load failed while importing _multiarray_umath: The specified module could not be found.       

During handling of the above exception, another exception occurred:

    import numpy as np

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:\Users\kkris\anaconda3\envs\cbf_gym\python.exe"
  * The NumPy version is: "1.20.1"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.

I verified that my path variables for anaconda and accurate and my previous environments are working.

    Does this answer your question? [numpy is already installed with Anaconda but I get an ImportError (DLL load failed: The specified module could not be found)](https://stackoverflow.com/questions/54063285/numpy-is-already-installed-with-anaconda-but-i-get-an-importerror-dll-load-fail) – Rabindra Mar 26 '21 at 19:05
  • I tried multiple of those answers. Magically it worked. Could not figure out which one exactly worked. – kosa Mar 26 '21 at 19:32
