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.

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.
