A custom collate_fn can be used to customize collation, e.g., padding sequential data to a max length of a batch. collate_fn is called with a list of data samples at each time. It is expected to collate the input samples into a batch for yielding from the data loader iterator.
What is a collate function?
Collate means that when printing more than one copy of a multi-page document, the copies will print all pages of each copy before printing the second copy. They are sorted into a correctly assembled sequence – and so if you are printing multiple copies it will then print them as sets of documents, not as single pages.
What is Pin_memory?
Pinned memory is used to speed up a CPU to GPU memory copy operation (as executed by e.g. tensor. cuda() in PyTorch) by ensuring that none of the memory that is to be copied is on disk. … The pin_memory field (pin_memory=True) on DataLoader invokes this memory management model.
