Hi everyone,
i try to train a faster rcnn detector, but i got some error like this:
Error using ./
Matrix dimensions must agree.
Error in vision.internal.cnn.layer.RPNCrossEntropy/backwardLoss (line 161)
dX = (-T./nnet.internal.cnn.util.boundAwayFromZero(Y))./numObservations;

i know some error about './' in basic operational matrix. but i don't have idea where i supose to be fixed in this case.
Is there a solution to this problem?

@Septian NLP - are you still running in to this issue? If so, can you upload your ground truth data and any other files required to run your code? That will help me reproduce the issue to see if I can provide a fix.

yes,sir,may be make image size to same,such as augmentedImageDatastore make image to 227*227
