基于基于paddlepaddle框架的安全帽检测
1.安装paddlex库的时候问题频出：
pip install paddlex
什么意思，安装成功了吗？还是说要指定版本，再指定一个网站？但是官方的也下载不了啊！
2.数据集切分出现问题：
!paddlex --split_dataset --format voc --dataset_dir /home/aistudio/helmet/ --val_value 0.2
报错：
If you cannot immediately regenerate your protos, some other possible workarounds are:
- Downgrade the protobuf package to 3.20.x or lower.
- Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates
什么意思，什么库又对应不上了？怎么看这么多博客都没人说。
pip install protobuf==3.19.0
按照这个把库降级就行了。
·但是我切分数据又不行了：
报错：
AttributeError: module 'pyarrow' has no attribute 'default_serialization_context'
这什么啊？有人解释一下吗？我记得我切分成功是安装了很多乱七八糟的库，现在忘了 ，但是我已经有一份切分好的数据集了。那么安装步骤，接下来就是调用train.py来训练数据集了吧。但是为什么调用这个文件问题这么多，为什么？
调用train.py文件进行数据训练
!python PaddleDetection/tools/train.py -c PaddleDetection/configs/yolov3/yolov3_darknet53_270e_voc.yml
看得我头疼：
python PaddleDetection/tools/train.py -c PaddleDetection/configs/yolov3/yolov3_darknet53_270e_voc.yml PaddleDetection/tools/train.py -c PaddleDetection/configs/yolov3/yolov3_darknet53_270e_voc.yml PaddleDetection/tools/train.py -c PaddleDetection/configs/yolov3/yolov3_darknet53_270e_voc.yml
