This is a summary of easily available, high-quality datasets consisiting of captioned image files for generalized DALLE-pytorch training (https://github.com/lucidrains/DALLE-pytorch).

The scripts help you download and resize the files from the given sources.

• general datasets
  • Conceptual Images 12m
  • Wikipedia
  • Filtered yfcc100m
  • Open Images
• specific datasets
  • None yet

All helper scripts can be found in the utilities folder now:

• TFrecords to WebDataset converter
• Image-Text-Folder to WebDataset converter
• Dataset sanitycheck for image-text-files
• Example reader for WebDataset files

The following command will look for image-text-pairs (.jpg / .png / .bmp) and return a csv table with incomplete data. When you add the optional argument -DEL, the incomplete files get deleted. The python scripts checks one folder and the first subdirectories.

python sanity_check.py --dataset_folder my-dataset-folder

If you want to continue training on pretrained models or even upload your own Dall-E model, head over to https://github.com/robvanvolt/DALLE-models

Special thanks go to Romaine, who improved the download scripts and made the great WebDataset format more accessible with his continuous coding efforts! 🙏

A lot of inspiration was taken from https://github.com/yashbonde/dall-e-baby - unfortunately that repo does not get updated anymore... Also, the shard creator was inspired by https://github.com/tmbdev-archive/webdataset-examples/blob/master/makeshards.py. The custom tokenizer was inspired by afiaka87, who showed a simple way to generate custom tokenizers with youtokentome.
