Fix ModuleNotFoundError

✅ Solution

The "ModuleNotFoundError" in vllm usually arises from missing dependencies or incorrect installation of required packages such as flash_attn or specific connector libraries. To resolve this, ensure all necessary packages are installed with the correct versions using `pip install -r requirements.txt` or by explicitly installing the missing module (e.g., `pip install flash-attn`). If using a specific connector, verify its installation instructions and compatibility with your hardware.
