ImportError: Module use of python27.dll conflicts with this version of Python

Question

Im currently trying to make a python script for Harris Corner Detection, and I keep getting this error no matter what other articles/fixes I find. Thanks for any help you can give.

Edit: Its the first line of the code that gives the error

Code:

import cv2
import numpy as np

filename = 'chessboard.jpg'
img = cv2.imread(filename)
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

gray = np.float32(gray)
dst = cv2.cornerHarris(gray,2,3,0.04)

#result is dilated for marking the corners, not important
dst = cv2.dilate(dst,None)

# Threshold for an optimal value, it may vary depending on the image.
img[dst>0.01*dst.max()]=[0,0,255]

cv2.imshow('dst',img)
if cv2.waitKey(0) & 0xff == 27:
    cv2.destroyAllWindows()

Answer 1

I had this issue occur also. In my environment settings I had a variable PYTHONPATH pointing to the directory of my Python 2.7 version of cv2.pyd. Updating this to the Python 3.4 version of the cv2.pyd directory fixed it.
