Hi, just wondering if this is still correct in README?

docker run --gpus all \
    -p 30000:30000 \
    -v ~/.cache/huggingface:/root/.cache/huggingface \
    --env "HF_TOKEN=<secret>" \
    --ipc=host \
    lmsysorg/sglang:latest \
    python3 -m sglang.launch_server --model-path meta-llama/Meta-Llama-3.1-8B-Instruct --host 0.0.0.0 --port 30000

I am building an alternative version of the image defined in Dockerfile and now getting the error added in this PR when I run python3 -m sglang.launch_server...

Yes it is still correct since it works for the lmsysorg/sglang:latest image in Docker Hub. I need to fix something in my Dockerfile - it worked before the latest updates. Anyway, my bad, apologies for disturbance!
