Padding and Strides

http://d2l.ai/chapter_convolutional-neural-networks/padding-and-strides.html

Hi,

I didn’t quite follow the comment written for the example of valid padding under 6.3.1 padding section. For the valid padding, there shouldn’t be any padding applied if I am not wrong. However, it is written that “padding numbers on either side of the height and width are 2 and 1” is applicable in comment. If padding applied, result will be different than returned by program.
