【目标检测】yolov5模型转换从pytorch到onnx到openvino（部署方式）

待我称王封你为后i 2022-10-17 04:08 788阅读 0赞

# 1.环境 #

yolov5环境中有onnx就可以，可以在另外的环境中单独安装openvino。

# yolov5的环境 + onnx
    onnx==1.9.0
    
    # openvino的环境
    openvino_2021.1.110

# 2.步骤 #

# 1. yolov5s pytorch model to onnx model （develop分支下）
    python3 models/export.py --weights ./weights/yolov5s.pt --img-size 640 --batch-size 1
    
    # 2. yolov5s onnx to openvino model
    python3 /opt/intel/openvino_2021.1.110/deployment_tools/model_optimizer/mo.py --input_model yolov5s.onnx --model_name yolov5s -s 255 --reverse_input_channels --output Conv_551,Conv_503,Conv_455
    
    # 3.1.1 test openvino model with CPU
    python3 yolo__openvino_demo.py -m yolov5s.xml -i voc/img/2007_000027.jpg -at yolov5 -d CPU
    
    # 3.1.2 test openvino model with GPU
    python3 yolo__openvino_demo.py -m yolov5s.xml -i voc/img/2007_000027.jpg -at yolov5 -d GPU
    
    # 3.2.1 test video openvino model with CPU
    python3 yolo__openvino_demo.py -m yolov5s.xml -i 2007_000027.mp4 -at yolov5 -d CPU
    
    # 3.2.2 test video openvino model with GPU
    python3 yolo__openvino_demo.py -m yolov5s.xml -i 2007_000027.mp4 -at yolov5 -d GPU

重点：

（1）转onnx的说明：

下面的代码支持yolov5的release v3-v5版本。使用[develop分支][develop]下转换onnx模型。确认最后有三个conv（40×40,20×20,80×80三个尺度之前的conv）。下面是v3（利用netron可视化获得下面conv的三个节点，就是转openvino时的--output三个参数）。

（2）转openvino的说明：

获得节点，点一下第一个conv，出现（以此类推），然后修改转onnx的节点（Conv\_551---Conv\_608）：
