+## 推理
+### 环境配置
+在[光源](https://www.sourcefind.cn/#/service-details)可拉取推理的docker镜像，在[光合开发者社区](https://cancon.hpccube.com:65024/4/main/)可下载onnxruntime安装包。asr_onnx推荐的镜像如下：
+```
+docker pull image.sourcefind.cn:5000/dcu/admin/base/pytorch:1.13.1-centos7.6-dtk-23.04-py37-latest
+```
+获取最新的dtk并安装依赖
+```
+cd /opt
+wget http://10.0.50.210:8000/jenkins/rocm/23.04.1/centos7/DTK-23.04.1-rc4-centos7-x86_64.tar.gz
+tar -zxvf DTK-23.04.1-rc4-centos7-x86_64.tar.gz
+source /opt/dtk-23.04.1/env.sh
+```
+下载模型(https://models.silero.ai/models/en/en_v5.onnx)到当前目录
+### 推理
+```
+python3 main.py --model_dir="./en_v5.onnx" --wav_dir="./wavs/" --warmup=1
+```
