Inference with Triton

Steps:

1. Prepare model repo files
   ```sh
   git-lfs install
   git clone https://www.modelscope.cn/damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch.git

pretrained_model_dir=$(pwd)/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch

cp $pretrained_model_dir/tokens.txt ./model_repo_paraformer_large_offline/scoring/
cp $pretrained_model_dir/am.mvn ./model_repo_paraformer_large_offline/feature_extractor/
cp $pretrained_model_dir/config.yaml ./model_repo_paraformer_large_offline/feature_extractor/

Refer here to get model.onnx (https://github.com/alibaba-damo-academy/FunASR/blob/main/funasr/export/README.md)

cp /model.onnx ./model_repo_paraformer_large_offline/encoder/1/
Log of directory tree: sh

8 directories, 9 files
```

1. Follow below instructions to launch triton server
   ```sh

   using docker image Dockerfile/Dockerfile.server

   docker build . -f Dockerfile/Dockerfile.server -t triton-paraformer:23.01
   docker run -it --rm --name "paraformer_triton_server" --gpus all -v <path_host/model_repo_paraformer_large_offline>:/workspace/ --shm-size 1g --net host triton-paraformer:23.01

launch the service

tritonserver --model-repository /workspace/model_repo_paraformer_large_offline \
--pinned-memory-pool-byte-size=512000000 \
--cuda-memory-pool-byte-size=0:1024000000

### Performance benchmark

Benchmark [speech_paraformer](https://www.modelscope.cn/models/damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch/summary) based on Aishell1 test set with a single V100, the total audio duration is 36108.919 seconds.

For client container:

docker run -it --rm --name "client_test" --net host --gpus all -v <path_host/triton_gpu/client>:/workpace/ soar97/triton-k2:22.12.1 # noqa

For aishell manifests:

apt-get install git-lfs
git-lfs install
git clone https://huggingface.co/csukuangfj/aishell-test-dev-manifests
sudo mkdir -p /root/fangjun/open-source/icefall-aishell/egs/aishell/ASR/download/aishell
tar xf ./aishell-test-dev-manifests/data_aishell.tar.gz -C /root/fangjun/open-source/icefall-aishell/egs/aishell/ASR/download/aishell/ # noqa

serveraddr=localhost
manifest_path=/workspace/aishell-test-dev-manifests/data/fbank/aishell_cuts_test.jsonl.gz
num_task=60
python3 client/decode_manifest_triton.py \
--server-addr $serveraddr \
--compute-cer \
--model-name infer_pipeline \
--num-tasks $num_task \
--manifest-filename $manifest_path
```

(Note: The service has been fully warm up.)
