Need help with an error.

[shuchitagupta]

I am constantly getting the error below. Can someone help? I have modified the code to run for multiple objects by initializing it with a new region to start with. Please help. It stops throwing this error at times.
Thanks.

File "run2.py", line 136, in
CMT.process_frame(im_gray)
File "/home/shuchita/Documents/Internship/CMT-master/CMT.py", line 245, in process_frame
selected_matches_all = self.matcher.knnMatch(features, self.selected_features, len(self.selected_features))
TypeError: object of type 'NoneType' has no len()

Start by determining why 'self' isn't the object you are expecting - in fact, it appears not to be an object at all. You may have the reference to self.selected_features wrong - or the scoping of the variable wrong. Just my thoughts.
