Emulator for Custom Handlers for Inference Endpoints

Emulator for Custom Handlers for Inference Endpoints

🤗 Inference Endpoints offers a secure production solution to easily deploy any 🤗 Transformers and Sentence-Transformers models from the Hub on dedicated and autoscaling infrastructure managed by Hugging Face.

🤗 Inference Endpoints support all of the 🤗 Transformers and Sentence-Transformers tasks as well as custom tasks not supported by 🤗 Transformers yet like speaker diarization and diffusion.

The hf-endpoints-emulator package provides a simple way to test your custom handlers locally before deploying them to Inference Endpoints. It is also useful for debugging your custom handlers.

The package provides a hf-endpoints-emulator command line tool that can be used to run your custom handlers locally. It also provides a hf_endpoint_emulator Python package that can be used to run your custom handlers locally from Python.
