尝试训练

反向commit 镜像：

docker commit 74d9893ccb29 kevinchina/deeplearning:fasterrcnn_train_v1

docker push kevinchina/deeplearning:fasterrcnn_train_v1

重启容器：

docker run --gpus all -it -v $PWD:/wkp --shm-size=64g kevinchina/deeplearning:fasterrcnn_train_v1 bash

训练：

conda activate py38
cd /deep-learning-for-image-processing/pytorch_object_detection/faster_rcnn/
python train_mobilenetv2.py

启动成功：

一轮训练完成后的验证：

安全帽数据训练

安全帽佩戴检测
数据集：https://github.com/njvisionpower/Safety-Helmet-Wearing-Dataset

加入安全帽数据，小小修改一下源代码的一些小的东西：

启动训练：
