Hi, I am trying to get the width attribute of an Image that I have loaded wtih cvLoadImage in python using the following code:

frame = cvLoadImage(name, CV_LOAD_IMAGE_GRAYSCALE)
xres = frame.width
yres = frame.height

when the program arrives to these ligne it get stack and gives the following error:

 Traceback (most recent call last):
      File "track.py", line 686, in <module>
      xres_max = frame.width
 AttributeError: 'NoneType' object has no attribute 'width'

Can you please help me solve this problem.

P.S: sorry for my english.

please, try to use the cv2 api instead of the outdated cv one.

import cv2
import numpy as np;
frame = cv2.imread(name,0)
print np.shape(frame)

baaaaaaaaaaaaaa.

get rid of those 'dependancy problems' in the 1st place.

any problems you might incur on the way are due to using outdated stuff., they are no more relevant today.

again, your english is not a problem at all, your usage of an outdated api is. (btw, you can imagine the difference between 1.0 and 2.4.9 ?)
