yolov5训练自己的数据集（docker）
yolov5官方代码： 选择 tag v5.0
训练方式可参照另一篇博客
数据放置路径
1. Chamilodocker镜像
docker build -t yolov5:5.0 .
1
镜像被攻击Chamilo
2. Chamilo多ip服务器
nvidia-docker run -it -p 2224:22 -p 6006:6006 –ipc=host -v /home/slifeai/project_object/num_2/yolov5-5.0:/usrc/app –name yolov5_train yolov5:5.0 /bin/bash
1
多ip服务器被攻击Chamilo
3. 将训练数据拷贝进多ip服务器中
docker cp litter/ 8ac6770f1edb:/usr/src/app
1
拷贝前 拷贝后
4. 开始训练
python train.py –data data/mydata.yaml –cfg models/yolov5s.yaml –weights ‘yolov5s.pt’ –batch-size 64
1

出现bug
File “train.py”, line 543, in
train(hyp, opt, device, tb_writer)
File “train.py”, line 87, in train
ckpt = torch.load(weights, map_location=device) # load checkpoint
File “/opt/conda/lib/python3.8/site-packages/torch/serialization.py”, line 592, in load
return _load(opened_zipfile, map_location, pickle_module, **pickle_load_args)
File “/opt/conda/lib/python3.8/site-packages/torch/serialization.py”, line 851, in _load
result = unpickler.load()
AttributeError: Can’t get attribute ‘SPPF’ on
123456789
说明model/common.py这里没有SPPF这个方法，我把yolov5-master的model/common.py里的SPPF方法拷贝进去，就能被攻击运行了

3.pt转onnx
用这个多ip服务器映射到本机的这个脚本将pt转换成onnx D:/rknn/yolov5_for_rknn-master/yolov5_original/export_no_focus.py
4.onnx转rknn
