I was able to create a PyTorch Dataset backed by S3 data using boto3 . Here's the snippet if anyone is interested.

You can use any command line tool as a URL source. For S3, the following should work: url = "pipe:s3cmd get s3://bucket/dataset-{ ...

Load WebDataset from remote, optionally caching, with the given preprocessing and batching. Parameters remote ( str) – Remote path (either an s3:// url or a directory on local filesystem). name ( str) – Name of this dataset, used to locate dataset in local cache. cache_dir ( str, optional) – Root directory of local filesystem cache.

Args: remote (str): Remote path (either an s3:// url or a directory on local filesystem). name (str): Name of this dataset, used to locate dataset in local cache. cache_dir (str, optional): Root directory of local filesystem cache. cache_verbose (bool): WebDataset caching verbosity. shuffle (bool): Whether to shuffle samples. shuffle_buffer ...

easy-to-deploy storage system, and WebDataset, a standards- ... object store providing an S3-like RESTful interface: read/write.

WebDataset scales perfectly from small, local datasets to petascale datasets and training on hundreds of GPUs and allows data to be stored on ...

We will then demonstrate the conversion of data stored in the webdataset format into TFRecord format using Amazon S3 Object Lambda.

Feb 17, 2022 · WebDataset training can be carried out directly against S3, GCS, and other cloud storage buckets NVIDIA's DALI library supports reading WebDataset format data directly there is a companion project to read WebDataset data in Julia the tarp command line program can be used for quick and easy dataset transformations of WebDataset data WebDataset

07.10.2020 · url = "pipe:s3cmd get s3://bucket/dataset-{000000..000999}.tar -" dataset = wds. Dataset ( url )... (Note that this use of command line tools is actually more efficient than the Python-native S3 client; that's why WebDataset does not use Python-native cloud libraries by default for accessing any storage.)

WebDataset is an ideal solution for training on petascale datasets kept on high performance distributed data stores like AIStore, AWS/S3, and Google Cloud. Compared to data center GPU servers, desktop machines have much slower network connections, but training jobs on desktop machines often also use much smaller datasets.

Capture C-level stdout/stderr in a context manager. require_webdataset. Hard require webdataset. size_webdataset. Calculate WebDataset with_epoch() and with_length().

Oct 07, 2020 · (Note that this use of command line tools is actually more efficient than the Python-native S3 client; that's why WebDataset does not use Python-native cloud libraries by default for accessing any storage.)

WebDataset reads dataset that are stored as tar files, with the simple convention that ... WebDataset training can be carried out directly against S3, GCS, ...

The Amazon S3 plugin for PyTorch is designed to be a high-performance PyTorch dataset library to efficiently access data stored in S3 buckets.
