WebOct 26, 2024 · In the forward definition, we pass in some x, ie. aggregated images for a batch from a DataLoader. Here, the 32x1x28x28 dimension indicates that there are 32 images in a batch. Do we just ignore this fact and Pytorch handles applying Conv2d to each sample? The forward propagation seems to be just relative to a single image.
