YOLO模型训练=》OPENVINO部署

简单整理了冲模型训练到openvino部署的相关内容。

YOLO模型的训练

1.下载darknet,进行编译。安装cuda、opencv、cudnn。

git地址:https://gitcode.net/mirrors/alexeyab/darknet

2.lable标注工具下载:

git地址:https://github.com/tzutalin/labelImg

3.训练数据准备

git地址:https://gitee.com/qiaokuankuan/object_detection.git

4.预训练模型参数下载,yolov3

git地址:https://pjreddie.com/media/files/darknet53.conv.74

5.训练模型

  • 标注训练数据的lable

  • 确认训练数据的类别:classes.txt

  • 获取训练数据的文件列表:trainlist.txt

  • 修改配置文件:voc.data

  • 修改配置模型cfg文件:yolov3-voc.cfg

  • 模型训练:
    ./darknet detector train /home/bhc/darknet-master/qkk/16/train/voc.data /home/bhc/darknet-master/qkk/16/train/yolov3-voc.cfg darknet53.conv.74

6.模型转换,yolo->pb

git地址:https://gitcode.net/mirrors/mystic123/tensorflow-yolo-v3

python3 ./convert_weights_pb.py --class_names /home/bhc/darknet-master/qkk/16/train/classes.txt --data_format NHWC --weights_file /home/bhc/darknet-master/backup1/16/16.weights 

7.模型转换,PB->IR

python3 /opt/intel/openvino_2021/deployment_tools/model_optimizer/mo_tf.py \
--input_model frozen_darknet_yolov3_model.pb \
--transformations_config yolo_v3.json \
--batch 1 \
--reverse_input_channels

8.openvino模型部署

git地址:https://gitcode.net/mirrors/PINTO0309/OpenVINO-YoloV3

9.gstreamer部署
