I've retrained cnn_inception_v2 for object detection. The training went fine, I tested it on some images and it worked. I wanted to use this new retrained model on OpenCV. I followed the insctruction here.

The pbtxt was created. but when running the openCV detection script I get the error :

Process finished with exit code -1073741819 (0xC0000005)

I've tried to see I was doing something wrong, so I did the same steps with the original Inception model and it worked.

I'm stuck at the moment.
