NVIDIA / TensorRT-LLM

TensorRT-LLM provides users with an easy-to-use Python API to define Large Language Models (LLMs) and build TensorRT engines that contain state-of-the-art optimizations to perform inference efficiently on NVIDIA GPUs. TensorRT-LLM also contains components to create Python and C++ runtimes that execute those TensorRT engines.

Reproduction

  1. Follow the guidance in homepage to setup TRT-LLM.
  2. Verify by python3 -c "import tensorrt_llm" and output the correct version.
  3. Follow the instruction on https://github.com/NVIDIA/TensorRT-LLM/tree/main/examples/server. Run python3 -m examples.server.server <path_to_tllm_engine_dir> <tokenizer_type> &
  4. Complains about uvicorn module not found
  5. pip install uvicorn
  6. After installation, running same command to start serving reports the following issue:

Even after I uninstall the uvicorn, the issue still persist

HamidShojanazeri commented 8 months ago

it seems the following working

follow the readme here and here. 

python3 server.py --model_dir /TensorRT-LLM/examples/llama/trt_engines/bf16/1-gpu/ --tokenizer_type /TensorRT-LLM/examples/llama/Llama-2-7b-ch

Seems like if you use apt-get install uvicorn then no issues, but pip install uvicorn (which can be installed as part of the requirements.txt) will cause this issue. Likely a version mismatch.
