Hi,
for testing purposes I imported the CatsVsDogs training set from here: https://www.kaggle.com/c/dogs-vs-cats
I am using a convnet in Keras for classification. My model seems to be working fine but there is a problem.
In the preprocessing I am resizing the images to 256x256 just for testing. Upon training I get the following error:
could not broadcast input array from shape (256,256,4) into shape (256,256,3)
So it seems like the preprocessing step bumps up my third image dimension to four channels.
Am I doing something wrong here?
