PyTorch Backend

Note:
This feature is currently experimental, and the related API is subjected to change in future versions.

To enhance the usability of the system and improve developer efficiency, TensorRT-LLM launches a new experimental backend based on PyTorch.

The PyTorch backend of TensorRT-LLM is available in version 0.17 and later. You can try it via importing tensorrt_llm._torch.

Quick Start

Here is a simple example to show how to use tensorrt_llm.LLM API with Llama model.
