Webdataset

WebDataset reads dataset that are stored as tar files, with the simple convention that files that belong together and make up a training sample share the same basename. WebDataset can read files from local disk or from any pipe, which allows it to access files using common cloud object stores.

As we demonstrate below, FFCV significantly outperforms existing systems such as Pytorch DataLoader, Webdataset, and DALI, while being much easier to use ...

Data stored in WebDataset format can be read with readers.webdataset operator. The operator takes the following arguments: paths the path (or list of paths) ...

Data Loading: Webdataset¶ Overview¶ This example shows you how to use the data stored in Webdataset format with DALI. Using readers.webdataset operator¶ Data stored in WebDataset format can be read with readers.webdataset operator. The operator takes the following arguments: paths the path (or list of paths) to the tar archives containing ...

Writing Filters and Offline Augmentation. Webdataset can be used for filters and offline augmentation of datasets. Here is a complete example that pre-augments a shard and extracts class labels. def extract_class(data): # mock implementation return 0 def augment(a): a += torch.randn_like (a) * 0.01 return a def augment_wds(url, output, maxcount ...

So Is there any easy way to wrap my dataset by webdataset? The documents here are mostly about imagenet which can be directly loaded and processed by tools ...

Since WebDatasets are just regular tar files, you can usually create them by just using the tarcommand. All you have to do is to arrange for any files that should be in the same sample to share the same basename. Many datasets already come that way. For those, you can simply create a WebDataset with $ tar --sort=name -cf dataset.tar dataset/

11.08.2020 · The WebDataset I/O library for PyTorch, together with the optional AIStore server and Tensorcom RDMA libraries, provide an efficient, simple, and standards-based solution to all these problems. The library is simple enough for day-to-day use, is based on mature open source standards, and is easy to migrate to from existing file-based datasets.

Getting Started. WebDataset reads dataset that are stored as tar files, with the simple convention that files that belong together and make up a training sample share the same basename. WebDataset can read files from local disk or from any pipe, which allows it to access files using common cloud object stores.

17.02.2022 · The WebDataset format represents images, movies, audio, etc. in their native file formats, making the creation of WebDataset format data as easy as just creating a tar archive. Because of the way data is aligned, WebDataset works well with block deduplication as well and aligns data on predictable boundaries.
