numpy is already installed with Anaconda but I get an ImportError (DLL load failed: The specified module could not be found)

Question

I am using the Anaconda distribution with Python 3.7. Among the packages installed, I have numpy, pandas, etc. In PyCharm IDE, I have set the Project Interpreter to be the p

Answer 1

Get the os environment path like:

import os
os.environ['PATH']

Now, add this path to the environment variable PATH in pycharm debugger/console output. It works.

Answer 2

I have actually figured out the solution. I had initially edited my System Environment Variable ‘PATH’ by adding the path to the Scripts folder in my Python executable directory. Turns out, this was NOT enough...

I had to add more paths to it, and that magically did the trick.

See below the paths I added for the System Environment Variable PATH:

C:\Users\<myusername>\AppData\Local\Continuum\Anaconda3\Scripts\
C:\Users\<myusername>\AppData\Local\Continuum\Anaconda3\Library\
C:\Users\<myusername>\AppData\Local\Continuum\Anaconda3\Library\bin\
C:\Users\<myusername>\AppData\Local\Continuum\Anaconda3\Library\mingw-w64\bin\

Now, I am not sure exactly which one path among these 4 my System was really looking for in particular. However, adding this combination sure did work for me

Answer 3

Even I was running the python file on command prompt, but the python.exe was from Anaconda. so when you run any python file you get,

Warning: This Python interpreter is in a conda environment, but the environment has not been activated. Libraries may fail to load. To activate this environment please see https://conda.io/activation.

you need to activate the environment by using this command

 conda init cmd.exe
 conda activate 

you see the command window as below, with base env

(base) C:\Users\yash\Documents\pycharm_project\venv>

Doing this I resolved this error

ImportError: numpy.core.multiarray failed to import Traceback (most recent call last): File "opencv_p1.py", line 2, in import cv2 File "E:\Anaconda3\lib\site-packages\cv2__init__.py", line 3, in from .cv2 import * ImportError: numpy.core.multiarray failed to import

In case you want to deactivate the conda use

 conda deactivate

Please follow this link in case you have any doubt https://conda.io/activation

Answer 4

Edit your System Environment Variable "PATH’ (refer steps here) by adding below given path.

Note: Follow this step if you already have numpy installed.

If using anaconda:
C:\Users\<username>\AppData\Local\Continuum\Anaconda<version>\Library\bin\

If using independent python interpreter:
C:\Users\<username>\AppData\Roaming\Python\Python<version>\Library\bin

For PyCharm users wanting an easy fix, this issue is fixed in PyCharm 2019.2.
