The official example for ray.data.llm.vLLMEngineProcessorConfig may throw a RuntimeError if there are version mismatches between Ray and vLLM, missing dependencies, or misconfigured environment variables. Common issues include using an unsupported vLLM version, missing CUDA drivers, or not setting required environment variables like VLLM_USE_V1. Upgrading to the latest Ray and vLLM versions and ensuring all dependencies are installed usually resolves these errors. For example, see the official docs and related issues.
