Whisper - Missing parameters for triton deployment using tensorrt_llm backend

[eleapttn]

System Info

Hello,

I'm trying to deploy Whisper large-v3 using Triton and tensorrtllm backend using this readme: https://github.com/triton-inference-server/tensorrtllm_backend/blob/v0.16.0/docs/whisper.md

Context

• hardware: L40S
• version of tensorrtllm_backend: v0.16.0
• checkpoint conversion done (success)
• TensorRT-LLM engines building done (success)

Issues

However, I have some issues when I'm trying to go to step 3 (Prepare Tritonserver configs) due to missing parameters to fill in config file using the following script:

python3 tools/fill_template.py -i model_repo_whisper/tensorrt_llm/config.pbtxt triton_backend:${BACKEND},engine_dir:${DECODER_ENGINE_PATH},encoder_engine_dir:${ENCODER_ENGINE_PATH},decoupled_mode:${DECOUPLED_MODE},max_tokens_in_paged_kv_cache:${MAX_TOKENS_IN_KV_CACHE},max_attention_window_size:${MAX_ATTENTION_WINDOW_SIZE},batch_scheduler_policy:${BATCH_SCHEDULER_POLICY},batching_strategy:${BATCHING_STRATEGY},kv_cache_free_gpu_mem_fraction:${KV_CACHE_FREE_GPU_MEM_FRACTION},exclude_input_in_output:${EXCLUDE_INPUT_IN_OUTPUT},triton_max_batch_size:${TRITON_MAX_BATCH_SIZE},max_queue_delay_microseconds:${MAX_QUEUE_DELAY_MICROSECONDS},max_beam_width:${MAX_BEAM_WIDTH},enable_kv_cache_reuse:${ENABLE_KV_CACHE_REUSE},normalize_log_probs:${NORMALIZE_LOG_PROBS},enable_chunked_context:${ENABLE_CHUNKED_CONTEXT},gpu_device_ids:${GPU_DEVICE_IDS},decoding_mode:${DECODING_MODE},max_queue_size:${MAX_QUEUE_SIZE},enable_context_fmha_fp32_acc:${ENABLE_CONTEXT_FMHA_FP32_ACC},cross_kv_cache_fraction:${CROSS_KV_CACHE_FRACTION},encoder_input_features_data_type:TYPE_FP16

My questions are:

• Why do we need a tensorrt_llm "model" to run the triton server for whisper_bls ?
• If it's required, how to set up these parameters for a Whisper model?

Thank you 🙂

Who can help?

Reproduction

In the https://github.com/triton-inference-server/tensorrtllm_backend/blob/v0.16.0/docs/whisper.md, at step 3:

python3 tools/fill_template.py -i model_repo_whisper/tensorrt_llm/config.pbtxt triton_backend:${BACKEND},engine_dir:${DECODER_ENGINE_PATH},encoder_engine_dir:${ENCODER_ENGINE_PATH},decoupled_mode:${DECOUPLED_MODE},max_tokens_in_paged_kv_cache:${MAX_TOKENS_IN_KV_CACHE},max_attention_window_size:${MAX_ATTENTION_WINDOW_SIZE},batch_scheduler_policy:${BATCH_SCHEDULER_POLICY},batching_strategy:${BATCHING_STRATEGY},kv_cache_free_gpu_mem_fraction:${KV_CACHE_FREE_GPU_MEM_FRACTION},exclude_input_in_output:${EXCLUDE_INPUT_IN_OUTPUT},triton_max_batch_size:${TRITON_MAX_BATCH_SIZE},max_queue_delay_microseconds:${MAX_QUEUE_DELAY_MICROSECONDS},max_beam_width:${MAX_BEAM_WIDTH},enable_kv_cache_reuse:${ENABLE_KV_CACHE_REUSE},normalize_log_probs:${NORMALIZE_LOG_PROBS},enable_chunked_context:${ENABLE_CHUNKED_CONTEXT},gpu_device_ids:${GPU_DEVICE_IDS},decoding_mode:${DECODING_MODE},max_queue_size:${MAX_QUEUE_SIZE},enable_context_fmha_fp32_acc:${ENABLE_CONTEXT_FMHA_FP32_ACC},cross_kv_cache_fraction:${CROSS_KV_CACHE_FRACTION},encoder_input_features_data_type:TYPE_FP16

Expected behavior

Variable not found when running the script:

python3 tools/fill_template.py -i model_repo_whisper/tensorrt_llm/config.pbtxt ...

Or in tritonserver logs:

[libprotobuf ERROR /tmp/tritonbuild/tritonserver/build/_deps/repo-third-party-build/grpc-repo/src/grpc/third_party/protobuf/src/google/protobuf/text_format.cc:337] Error parsing text-format inference.ModelConfig: 105:16: Expected integer or identifier, got: $

actual behavior

Missing parameters to fill the config.pbtxtx

additional notes

Tried to add the parameters as follow but still missing other parameters
