BatchNormalization(axis = 1) when used on convolutional layers

This is slightly confusing: is “th” refering to Theano and “tf” to TensorFlow, thus axis sign is reversed based on the backend used by Keras ?

It the different default dimension ordering. For theano, channel is the 2nd dim, for tensorflow, it’s the last dim.
