YOLOv5 in tesnorflow2.x-keras

模型测试

  • 训练 COCO2017(val 5k)

  • 检测效果

  • 精度/召回率

Requirements

pip3 install -r requirements.txt

Get start

  1. 训练
python3 train.py
  1. tensorboard
tensorboard --host 0.0.0.0 --logdir ./logs/ --port 8053 --samples_per_plugin=images=40
  1. 查看
http://127.0.0.1:8053
  1. 测试, 修改detect.py里面input_imagemodel_path
python3 detect.py

训练自己的数据

  1. labelme打标自己的数据
  2. 打开data/labelme2coco.py脚本, 修改如下地方
input_dir = '这里写labelme打标时保存json标记文件的目录'
output_dir = '这里写要转CoCo格式的目录,建议建一个空目录'
labels = "这里是你打标时所有的类别名, txt文本即可, 每行一个类, 类名无需加引号"
  1. 执行data/labelme2coco.py脚本会在output_dir生成对应的json文件和图片
  2. 修改train.py文件中coco_annotation_file以及num_class, 注意classes通过CoCoDataGenrator(*).coco.cats[label_id]['name']可获得,由于coco中类别不连续,所以通过coco.cats拿到的数组下标拿到的类别可能不准.
  3. 开始训练, python3 train.py
