      To expedite the response to your issue, it would be helpful if you could identify the appropriate person
      to tag using the **@** symbol. Here is a general guideline on **whom to tag**.

      Rest assured that all issues are reviewed by the core maintainers. If you are unsure about whom to tag,
      you can leave it blank, and a core maintainer will make sure to involve the appropriate person.

      Please tag fewer than 3 people.

      Please provide a clear and concise description of what the bug is and how to reproduce it.

      If relevant, add a minimal example so that we can reproduce the error by running the code. It is very important for the snippet to be as succinct (minimal) as possible, so please take time to trim down any irrelevant code to help us debug efficiently. We are going to copy-paste your code and we expect to get the same result as you did: avoid any external data, and include the relevant imports, etc. For example:

      ```python
      from tensorrt_llm import LLM
      from tensorrt_llm.sampling_params import SamplingParams

      prompts = [
          "Hello, my name is",
          "The president of the United States is",
          "The capital of France is",
          "The future of AI is",
      ]
      sampling_params = SamplingParams(temperature=0.8, top_p=0.95)

      llm = LLM(model="meta-llama/Llama-3.1-8B-Instruct")

      outputs = llm.generate(prompts, sampling_params)

      # Print the outputs.
      for output in outputs:
          prompt = output.prompt
          generated_text = output.outputs[0].text
          print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")
      ```

      If the code is too long (hopefully, it isn't), feel free to put it in a public gist and link it in the issue: https://gist.github.com.

      Remember to use code tags to properly format your code. You can refer to the
      link https://help.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks#syntax-highlighting for guidance on code formatting.

      Please refrain from using screenshots, as they can be difficult to read and prevent others from copying and pasting your code.
      It would be most helpful if we could reproduce your issue by simply copying and pasting your scripts and codes.

      Please set the environment variable `export TLLM_DEBUG_MODE=1` to turn on more logging to help debugging potential issues.

      ⚠️ Please separate bugs of `transformers`, `pytorch` implementation or usage from bugs of `TensorRT-LLM`.

      - If the error only appears in TensorRT-LLM, please provide the detailed script of how you run `TensorRT-LLM`, also highlight the difference and what you expect.

      Thanks for reporting 🙏!
