Hi, Ian.

Sorry, I don’t understand your point. Which exercise are you talking about? If you mean conv_forward, there are literally 4 levels of nested loop there. You also have to be very careful with the indentation: that is critical for defining the body of the loops in python, right?

The loop structure in conv_forward is this:

for every sample:
   for every vertical position in the output space:
      for every horizontal position in the output space;
         for every output channel:
            do the computation
