Caffe to Keras conversion of grouped convolution

https://stackoverflow.com/questions/54610665/caffe-to-keras-conversion-of-grouped-convolution

That means you got a grouped convolution there ( Caffe: What does the group param mean? ). Technically that means that you have two filters, each of shape (128, 48, 5, 5). The first one will convolve with the first 48 channels and produce the first 128 outputs, the second one is for the remaining ones.
