# PyTorch Backend
|
|
|
|
```{note}
|
|
Note:
|
|
This feature is currently in beta, 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 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.
|
|
|
|
```{literalinclude} ../../examples/llm-api/quickstart_example.py
|
|
:language: python
|
|
:linenos:
|
|
```
|
|
|

## Known Issues
|
|
|
|
- The PyTorch backend on SBSA is incompatible with bare metal environments like Ubuntu 24.04. Please use the [PyTorch NGC Container](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/pytorch) for optimal support on SBSA platforms.
