### Steps:
|
||
|
|
1. Prepare model repo files
|
||
|
|
* git clone https://www.modelscope.cn/damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-online-onnx.git
|
||
|
|
* Convert lfr_cmvn_pe.onnx model. For example: python export_lfr_cmvn_pe_onnx.py
|
||
|
|
* If you export to onnx, you should have several model files in `${MODEL_DIR}`:
|
||
|
|

2. 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_online>:/workspace/ --shm-size 1g --net host triton-paraformer:23.01
|
||
|
|
|
||
|
|
# launch the service
|
||
|
|
cd /workspace
|
||
|
|
tritonserver --model-repository model_repo_paraformer_large_online \
|
||
|
|
--pinned-memory-pool-byte-size=512000000 \
|
||
|
|
--cuda-memory-pool-byte-size=0:1024000000
|
||
|
|
|
||
|
|
```

### Performance benchmark with a single A10
|
||
|
|
|
||
|
|
* FP32, onnx, [paraformer larger online](https://modelscope.cn/models/damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-online-onnx/summary
|
||
|
|
),Our chunksize is 10 * 960 / 16000 = 0.6 s, so we should care about the perf of latency less than 0.6s so that it can be a realtime application.
|

|
|
|
||
|
|
|
||
|
|
| Concurrency | Throughput | Latency_p50 (ms) | Latency_p90 (ms) | Latency_p95 (ms) | Latency_p99 (ms) |
