• If I'm not mistaken, it should be possible to use tensorrt_llm.llmapi.LLM with LLM(..., backend='pytorch'), instead of tensorrt_llm._torch.LLM, right?
• Would it be possible to make this class a general wrapper of LLM for any backed? That would be useful for deploying modelopt unified checkpoints and HFAutoModels in trt-llm
