Using this guide on how to implemenent VGG19 from scratch, I changed the input shape but gives error. How do I modify this layer to accept images with more than 3 channels?

Changed from:

input_shape = (224,224,3)

to:

input_shape = (32, 32, 6)

error:

ValueError: Input 0 of layer "vgg19" is incompatible with the layer: expected shape=(None, 32, 32, 6), found shape=(None, 32, 32, 3)
