I'm pretty new to python and this code is for object detection, it works fine on my webcam but has an error when using an external camera
This is what I have:
for classId, confidence,box in zip(classIds.flatten(),confs.flatten(),bbox):
cv2.rectangle(img,box,color=(0,255,0),thickness=2)
cv2.putText(img,classNames[classId-1].upper(),(box[0]+10,box[1]+30),
cv2.FONT_HERSHEY_COMPLEX,1,(0,255,0),2)
Here's the message I got:
Traceback (most recent call last):
File "C:/Users/byeo9/PycharmProjects/FYP-ENV/Testing 2.py", line 31, in <module>
for classId, confidence,box in zip(classIds.flatten(),confs.flatten(),bbox):

I am trying to scrap specific information from the site but I am receiving an error. Here is the simplified version of the main problem:
import re

c=re.search('href="/bp/vendor?vendorCodes=C901U">C901U</a></span></div></div></div><div',b)
If I try to find what is in c I receive this error:
c.group()

AttributeError: 'NoneType' object has no attribute 'group'
Thanks in advance.

I am running a Python program in Raspberry Pi on startup (autostart) that I have placed in .bashrc but on startup, OpenCV code snippet contained file is not loading but normal Python program is running and I was using KNN(K Nearest Neighbour) on this algorithm I am getting the following error.

I just started using OpenCV 3.0 in python. I am trying one of the example "didgits.py" and I am getting the Attribute error:
Traceback (most recent call last):
File "C:\Users\Arpit Jindal\Desktop\opencv\sources\samples\python2\digits.py", line 171, in <module>
model = KNearest(k=4)

self.model = cv2.KNearest()
AttributeError: 'module' object has no attribute 'KNearest'
Then I commented the code for KNearest and tried for SVM only and again I got the Attribute error:
Traceback (most recent call last):

I tried to search for these variable in OpenCV but couldn't find anything.
Are the python examples not updated? Where can I find the complete list of python API's and reference manual for OpenCV3.0 python, as the online docs is not complete for Machine Learning because I found many python API mentioned in 2.4.9 but not in 3.0?
hello to every one, I want ro run camshift algorithm but an error is created during running time. The error is:
Traceback (most recent call last):
File "C:\Python27\code\extra algorithms\Camshift in OpenCV.py", line 11, in <module>
roi = frame[r:r+h, c:c+w] TypeError: 'NoneType' object has no attribute '__getitem__10'
`
Probably frame is None. So you can't index it like you're doing in frame[r:r+h, c:c+w]. You should initialize the variable or handle the case when it's None.
