Fix NotImplementedError

✅ Solution

The "NotImplementedError" in vllm usually arises when a specific CUDA kernel or functionality (like a specific attention mechanism, quantization method, or hardware architecture support) hasn't been implemented for the detected GPU's architecture or requested feature. To fix it, either ensure you're using a supported GPU and feature combination according to vllm's documentation, or contribute the missing CUDA kernel implementation for the specific architecture/feature and submit a pull request to the vllm repository.
