03.10.2018 · I’m trying to work out whether the torch.utils.data.WeightedRandomSampler class will still cover all available data inputs provided a long enough training period when choosing sampling with replacement. Given that WeightedRandomSampler requires shuffle=False in the DataLoader, does that mean that WeightedRandomSampler will observe the entire sampling …

PyTorch provides two data primitives: torch.utils.data.DataLoader and torch.utils.data.Dataset that allow you to use pre-loaded datasets as well as your own data. Dataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples.

21.10.2021 · During the training, I would like to sample batches of m training samples, with replacement; e.g. the first iteration includes data indices [1, 5, 6], second iteration includes data points [12, 3, 5], and so on and so forth. So the total number of iterations is an input, rather than N/m. Is there a way to use dataloader to handle this?

Jan 23, 2020 · Generate samples on the fly in the RandomSampler if replacement=True. Motivation. My primary use of random sampler with replacement=True would be to have an infinite sampler of random elements that do not require a restart of the loader processes. To do this, I would like to specify a big number of samples with replacement=True.

PyTorch script. Now, we have to modify our PyTorch script accordingly so that it accepts the generator that we just created. In order to do so, we use PyTorch's DataLoader class, which in addition to our Dataset class, also takes in the following important arguments:. batch_size, which denotes the number of samples contained in each generated batch. ...
