# WhisperLive-TensorRT
We have only tested the TensorRT backend in docker so, we recommend docker for a smooth TensorRT backend setup.
**Note**: We use `tensorrt_llm==0.15.0.dev2024111200`
**Note**: We use `tensorrt_llm==0.18.2`
## Installation
- Install [docker](https://docs.docker.com/engine/install/)

By default trt_backend uses cpp_session, to use python session pass `--trt_py_session` to run_server.py
