Pytorch reduce batch size
WebJun 13, 2024 · In the code above, we created a DataLoader object, data_loader, which loaded in the training dataset, set the batch size to 20 and instructed the dataset to shuffle at each epoch. Iterating over a PyTorch DataLoader Conventionally, you will load both the index of a batch and the items in the batch. WebJan 19, 2024 · Technically speaking, the size of the activations is linearly dependent on the batch size. It is now clearly noticeable that increasing the batch size will directly result in increasing the required GPU memory. In many cases, not having enough GPU memory prevents us from increasing the batch size.
