Describe the Bug

Installing a worker in a GPU server with Nvidia L20 chips has failed, resulting in an error message indicating that the device driver is not capable of handling GPU operations.

Steps to Reproduce

To reproduce this issue, follow these steps:

Run the add worker command: Execute the following command in the GPU machine to add a new worker:

sudo docker run -d --name gpustack-worker-1 --restart=unless-stopped --gpus all -p 10150:10150 -p 40000-41024:40000-41024 -p 50000-51024:50000-51024 --ipc=host -v gpustack-worker-data:/var/lib/gpustack gpustack/gpustack:v0.5.1 --server-url --token --worker-ip

   Replace `<url>`, `<token>`, and `<worker-ip>` with the actual values for your setup.

**Result**
------------

The command execution results in the following error message:

docker: Error response from daemon: could not select device driver "" with capabilities: [[gpu]].
