PyTorch Prototype Recipes

Created On: Mar 03, 2021 | Last Updated: Oct 10, 2024 | Last Verified: Nov 05, 2024

Prototype features are not available as part of binary distributions like PyPI or Conda (except maybe behind run-time flags). To test these features we would, depending on the feature, recommend building from master or using the nightly wheels that are made available on pytorch.org.

Level of commitment: We are committing to gathering high bandwidth feedback only on these features. Based on this feedback and potential further engagement between community members, we as a community will decide if we want to upgrade the level of commitment or to fail fast.
