IF vLLM server fails to start with 'RuntimeError: Failed to infer device type' and logs show 'UnspecifiedPlatform'.

How others solved it

THEN Ensure the Docker container has access to GPU drivers by verifying that nvidia-smi runs successfully inside the container. If nvidia-smi is not found, re-run the container with proper GPU passthrough (e.g., --gpus all) or use a base image with NVIDIA CUDA toolkit included. Additionally, set VLLM_LOGGING_LEVEL=DEBUG to get more verbose logs for debugging.

docker exec <container> nvidia-smi
