NVIDIA Jetson Orin - SGLang Documentation

Prerequisites

Before starting, ensure the following:

NVIDIA Jetson AGX Orin Devkit is set up with JetPack 6.1 or later.
CUDA Toolkit and cuDNN are installed.
Verify that the Jetson AGX Orin is in high-performance mode:

sudo nvpmodel -m 0

Installing and running SGLang with Jetson Containers

Clone the jetson-containers github repository:

git clone https://github.com/dusty-nv/jetson-containers.git

Run the installation script:

bash jetson-containers/install.sh

Build the container image:

jetson-containers build sglang

Run the container:

jetson-containers run $(autotag sglang)

Or you can also manually run a container with this command:

docker run --runtime nvidia -it --rm --network=host IMAGE_NAME

Running Inference

Launch the server:

python -m sglang.launch_server \
  --model-path deepseek-ai/DeepSeek-R1-Distill-Llama-8B \
  --device cuda \
  --dtype half \
  --attention-backend flashinfer \
  --mem-fraction-static 0.8 \
  --context-length 8192

The quantization and limited context length (--dtype half --context-length 8192) are due to the limited computational resources in Nvidia jetson kit. A detailed explanation can be found in Server Arguments. After launching the engine, refer to Chat completions to test the usability.
