opencv runs in python but not in spyder

Question

I am a complete beginner to opencv . I wrote this code in spyder and it shows no module named 'cv2'

import cv2
img = cv2.imread('D:\ML\img1.jfif',1)
cv2.imshow('D:\ML\img1.jfif',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

but the same code works in the python cmd

any help is appreciated. Thank you

Answer 1

Probably a diffent Python interpreter / executable for each case:

You can check:

import sys
print(sys.executable)

Answer 2

There are multiple reasons why this could be the case.

1. May you work in a virtual environment in which your cv2 package is not "known".
2. You have the wrong cv2 package for your python version.
3. Maybe you use the wrong interpreter (eg. if you have a python2 and python3 interpreter but pip installed cv2 for the wrong one).

Plase provide which python interpreter you have set up for your Spyder, if this is the only installed python on your path and how you installed cv2.

Best regards and good luck!
