# Data[[timm.data.create_dataset]]

- **name** -- Dataset name, empty is okay for folder based datasets
- **root** -- Root folder of dataset (All)
- **split** -- Dataset split (All)
- **search_split** -- Search for split specific child fold from root so one can specify
  `imagenet/` instead of `/imagenet/val`, etc on cmd line / config. (Folder, Torch)
- **class_map** -- Specify class -> index mapping via text file or dict (Folder)
- **load_bytes** -- Load data, return images as undecoded bytes (Folder)
- **download** -- Download dataset if not present and supported (HFIDS, TFDS, Torch)
- **is_training** -- Create dataset in train mode, this is different from the split.
  For Iterable / TDFS it enables shuffle, ignored for other datasets. (TFDS, WDS, HFIDS)
- **batch_size** -- Batch size hint for iterable datasets (TFDS, WDS, HFIDS)
- **seed** -- Seed for iterable datasets (TFDS, WDS, HFIDS)
- **repeats** -- Dataset repeats per iteration i.e. epoch (TFDS, WDS, HFIDS)
- **input_img_mode** -- Input image color conversion mode e.g. 'RGB', 'L' (folder, TFDS, WDS, HFDS, HFIDS)
- **trust_remote_code** -- Trust remote code in Hugging Face Datasets if True (HFDS, HFIDS)
- ****kwargs** -- Other args to pass through to underlying Dataset and/or Reader classesDataset object
Dataset factory method

In parentheses after each arg are the type of dataset supported for each arg, one of:
* Folder - default, timm folder (or tar) based ImageDataset
* Torch - torchvision based datasets
* HFDS - Hugging Face Datasets
* HFIDS - Hugging Face Datasets Iterable (streaming mode, with IterableDataset)
* TFDS - Tensorflow-datasets wrapper in IterabeDataset interface via IterableImageDataset
* WDS - Webdataset
* All - any of the above
