WebMay 7, 2024 · In PyTorch, every method that ends with an underscore ( _) makes changes in-place, meaning, they will modify the underlying variable. Although the last approach worked fine, it is much better to assign tensors to a device at the moment of their creation. WebShuffle and repeat. When training on a dataset, we often need to repeat it for multiple epochs and we need to shuffle it. One big caveat when shuffling is to make sure that the buffer_size argument is big enough. The bigger it is, the longer it is going to take to load the data at the beginning. However a low buffer size can be disastrous for ...
