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.

the inference results of TRT-LLM are different from the HF model results(chatglm3-6b tools call mode) #1561

Reproduction

    Use HF function just like model.chat(tokenizer, query, history=history) to inference our model, the result is correct. But use tensorrt_llm to inference our model , the result is abnormal。
    The execute script in tensorrt_llm framework is just like this: "python3 ../run.py --input_text "What's new between ChatGLM3-6B and ChatGLM2-6B?" \
              --max_output_len 50 \
              --tokenizer_dir chatglm3_6b \
              --engine_dir trt_engines/chatglm3_6b/fp16/1-gpu")。
       There seems to be a big difference  between ModelRunner.generate() method in tensorrt_llm and .chat() method in HF framework. Can you give me some suggestions to solve this problem?

Could you check that you have aglined the inputs (the input ids before entering the transformer layer are same) and the sampling/beamsearch arguments like topk, topp, temeperature, etc.

yes, i keep input_ids(tools prior definition + query) and sampling/beamsearch arguments the same and output results are different

Hi @FanZhang91 do u still have further issue or question now? If not, we'll close it soon.
