I0310 14:31:03.640287 7170 net.cpp:761] Ignoring source layer accuracy I0310 14:31:03.640292 7170 net.cpp:761] Ignoring source layer prob Traceback (most recent call last): File "Scripts/webcam_demo.py", line 34, in label_colours = cv2.imread(args.colours).astype(np.uint8) AttributeError: 'NoneType' object has no attribute 'astype'

HOW to solve this problem? Thanks

I have the same problem I0706 18:48:28.640565 3858 net.cpp:761] Ignoring source layer accuracy I0706 18:48:28.640568 3858 net.cpp:761] Ignoring source layer prob Traceback (most recent call last): File "Scripts/webcam_demo.py", line 34, in label_colours = cv2.imread(args.colours).astype(np.uint8) AttributeError: 'NoneType' object has no attribute 'astype'

Did you solve it?

Probably you give a incorrect path to imread, see: http://www.pyimagesearch.com/2016/12/26/opencv-resolving-nonetype-errors/

this issue could be the '/' in beginning of path, call python Scripts/webcam_demo.py --model Example_Models/segnet_model_driving_webdemo.prototxt --weights Example_Models/segnet_weights_driving_webdemo.caffemodel --colours Scripts/camvid12.png

instead of: python Scripts/webcam_demo.py --model Example_Models/segnet_model_driving_webdemo.prototxt --weights /Example_Models/segnet_weights_driving_webdemo.caffemodel --colours /Scripts/camvid12.png

me pueden ayudar con este error (esta en negritas) gracias
