Docker

We recommend starting with our pre-built Docker image to avoid compiling custom CUDA kernels and other dependencies.

Run container with base LLM

In this example, we'll use Mistral-7B-Instruct as the base model, but you can use any supported model from HuggingFace.

model=mistralai/Mistral-7B-Instruct-v0.1
volume=$PWD/data  # share a volume with the container as a weight cache

docker run --gpus all --shm-size 1g -p 8080:80 -v $volume:/data \
    ghcr.io/predibase/lorax:main --model-id $model

!!! note

The `main` tag will use the image built from the HEAD of the main branch of the repo. For the latest stable image (built from a 
tagged version) use the `latest` tag.

!!! note

The LoRAX server in the pre-built Docker image is configured to listen on port 80 (instead of on the default port number, which is 3000).

!!! note

To use GPUs, you need to install the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html). We also recommend using NVIDIA drivers with CUDA version 11.8 or higher.

See the references docs for the Launcher to view all available options, or run the following from within your container:

lorax-launcher --help
