Hi @MariosOreo,
It is a mistake from my part. Yes, the batch_size is 1 in this place.  I will correct the details. But still the output in my side is also torch.Size([1, 64, 15, 159])  which is different from the results gained from the equations. It is not supposed to output this results right? or am I missing something in this equation?  If my knowledge goes correctly, subtraction of kernel size from height or width of the image must be divisible by the stride but in this example, it is not divisible. I did not do any padding here too. That is where I am confused.
sincerely,
Htut Lynn Aung
