Details

  • Hugging Face introduced a Space to check if Transformers models run unmodified on AWS Trainium using the TorchNeuron backend.
  • The tool tests models on Trainium2 (trn2) instances, sharding across up to 16 cores (4 devices) and generating 32 tokens to verify output.
  • Results are stored in a public dataset (aws-neuron/torch-neuronx-model-support) with Parquet files per compiler and library version, allowing direct querying via pandas.
  • Users can retrieve the exact Neuron stack, packages, and run.py script used for each model, including commands to sync compiled graphs from a public NEFF cache to skip compilation.
  • Current coverage is limited to text-generation and image-text-to-text models; plans exist to expand to diffusers and sentence transformers.
