Witryna14 mar 2024 · Specifically, the Vision Transformer is a model for image classification that views images as sequences of smaller patches. As a preprocessing step, we split an image of, for example, pixels into 9 patches. Each of those patches is considered to be a “word”/“token”, and projected to a feature space. WitrynaThe input to the model is expected to be a list of tensors, each of shape ``[C, H, W]``, one for each image, and should be in ``0-1`` range.

By default, torch stacks the input image to from a tensor of size N*C*H*W, so every image in the batch must have the same height and width. In order to load a batch with variable size input image, we have to use our own collate_fn which is used to pack a batch of images.
