Who can help?

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction

Build for source by cloning the main on tensorrtllm_backend

# Update the submodules
cd tensorrtllm_backend
git lfs install
git submodule update --init --recursive

# Use the Dockerfile to build the backend in a container
# For x86_64
DOCKER_BUILDKIT=1 docker build -t triton_trt_llm -f dockerfile/Dockerfile.trt_llm_backend .

Download weights from HF

pip install -r requirements.txt # install latest version of transformers, needed for Mixtral

git lfs install
git clone https://huggingface.co/mistralai/Mixtral-8x7B-v0.1

Set Directory and generate engines

export HF_LLAMA_MODEL=/path/Mixtral-8x7B-v0.1
export UNIFIED_CKPT_PATH=/path/mixtral-56B/
export ENGINE_PATH=/path/tensorrtllm_backend/all_models/inflight_batcher_llm/tensorrt_llm/1/

python3 ./examples/llama/convert_checkpoint.py --model_dir ${HF_LLAMA_MODEL} \
                             --output_dir ${UNIFIED_CKPT_PATH} \
                             --dtype float16 \
                             --tp_size 2 \
                             --dtype float16 \
                            --use_weight_only \
                            --weight_only_precision int4 

python3 -m tensorrt_llm.commands.build --checkpoint_dir ${UNIFIED_CKPT_PATH} \
                 --output_dir ${ENGINE_PATH} \
                 --gemm_plugin float16 \
                 --max_input_len 32000 \

Then Start your triton server like so

cp all_models/inflight_batcher_llm/ mixtral_ifb -r

python3 tools/fill_template.py -i mixtral_ifb/preprocessing/config.pbtxt tokenizer_dir:${HF_LLAMA_MODEL},triton_max_batch_size:64,preprocessing_instance_count:1
python3 tools/fill_template.py -i mixtral_ifb/postprocessing/config.pbtxt tokenizer_dir:${HF_LLAMA_MODEL},triton_max_batch_size:64,postprocessing_instance_count:1
python3 tools/fill_template.py -i mixtral_ifb/tensorrt_llm_bls/config.pbtxt triton_max_batch_size:64,decoupled_mode:False,bls_instance_count:1,accumulate_tokens:False
python3 tools/fill_template.py -i mixtral_ifb/ensemble/config.pbtxt triton_max_batch_size:64
python3 tools/fill_template.py -i mixtral_ifb/tensorrt_llm/config.pbtxt triton_backend:tensorrtllm,triton_max_batch_size:64,decoupled_mode:False,max_beam_width:1,engine_dir:${ENGINE_PATH},max_tokens_in_paged_kv_cache:20000,max_attention_window_size:2560,kv_cache_free_gpu_mem_fraction:0.5,exclude_input_in_output:True,enable_kv_cache_reuse:False,batching_strategy:inflight_fused_batching,max_queue_delay_microseconds:0

python3 scripts/launch_triton_server.py --world_size=2 --model_repo=mixtral_ifb/ --log

Finally in a separate terminal

sudo docker run --gpus all --rm -it --net host -v /home/azureuser/:/home/azureuser/ nvcr.io/nvidia/tritonserver:24.03-py3-sdk

perf_analyzer -m ensemble --input-data llm_inputs.json --measurement-interval 45000 --service-kind triton --request-rate-range 0.5:1.5:0.5 --request-distribution constant --stability-percentage 1000 -i grpc -u localhost:8001 --shape max_tokens:1 --shape text_input:1 -f output2k_large.csv --verbose-csv --collect-metrics

Expected behavior

The expected behavior should be getting thoughput and latency numbers

actual behavior

Command just hangs and doesnt return anything

*** Measurement Settings ***
  Batch size: 1
  Service Kind: Triton
  Using "time_windows" mode for stabilization
  Measurement window: 45000 msec
  Latency limit: 0 msec
  Request Rate limit: 1.5 requests per seconds
  Using uniform distribution on request generation
  Using synchronous calls for inference
  Stabilizing using average latency

Request Rate: 0.5 inference requests per seconds
failed to find the requested model version

additional notes

I wrote a custom script which uses gprc over tritonclient to send synchronous requests. Initially it completes the request in 8seconds but after 40 such requests it just hangs.

The tritonserver logs after verbosity are like this

And never returns a response back and just hands

Quantization to int 4 doesnt help either

Hi @aaditya-srivathsan, I've seen some similar issues reported that were solved by setting --use_custom_all_reduce disable.

Can you try this to see if it helps?

[aaditya-srivathsan]

Sure let me try this and ill let you know if this works or not

[aaditya-srivathsan]

This did help thank you very much!
