19.03.2020 · First, my dataset class does not modify the data loaded (from HDF files, in this case). On the computers I run my models on, there is not enough ram to hold all of the dataset items. To speed up loading, I have been caching up to a specific count. Then, in get_item it just tests if the item is cached, and returns that, or loads the item from disk. However, this means …

14.03.2017 · Are there any solutions (or ideas) how to cache datasets? I have quite a bit of pre-processing in the respective __getitem__ implementation of torch.utils.data.Dataset which are recalculated on every epoch.

04.04.2021 · Hey, I’m training a standard resnet50 classifier on Imagenet dataset, which contains over 1M images and weights 150+ GB. I’m using my own training script, but it’s a basic code using my torch dataloader on top of my own costume dataset. My dataset is simple, in the init function it just saves the path to all the images, and in the getitem function it loads the image from the …

13.06.2018 · Hi, Currently, I am in a situation: the dataset is stored in a single file on a shared file system and too many processes accessing the file will cause a slow down to the file system (for example, 40 jobs each with 20 workers will end up 800 processes reading from the same file). So I plan to load the dataset to the memory. I have enough memory (~500G) to hold the entire …

Mar 29, 2020 · Better and more robust caching supports already exist in python core lib (functools.lru_cache) and 3rd party libs specialized for this (e.g., ring, methodtools etc.). I don't think PyTorch should maintain another copy. When worker reusing is implemented, users could just use these existing decorators to add caching to their datasets.

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.

Args: data_set (torch.utils.data.Dataset): The raw `torch.utils.data.Dataset` to be cached. It can be set to `None` in case all the input samples are stored within the `path` folder. path (string): The path where the dataset samples should be stored/loaded. The `path` needs to be writeable, unless all the samples are already stored.

During training call set_data() to update input data and recompute cache content, note that it requires persistent_workers=False in the PyTorch DataLoader. Note.

29.03.2020 · edited by pytorch-probot bot Feature For datasets that fit into memory, but the samples are loaded individually a cache could decrease the time needed to fetch the samples. In each call to the dataset the cache should be checked for the existence of the object to be loaded and if possible return the cached sample. Motivation

22.04.2020 · You can use Python's LRU Cache functionality to cache some outputs. You can also use torchdata which acts almost exactly like PyTorch's torch.utils.data.Dataset but allows caching to disk or in RAM (or mixed modes) with simple cache () on torchdata.Dataset (see github repository, disclaimer: i'm the author ).
