1、self._handle = _dlopen(self._name, mode) OSError: [WinError 126] 找不到指定的模块

shapely版本有问题

conda install -c conda-forge shapely 

2、需要在本地电脑安装CUDA+cudnn，在anaconda安装不行，必须本地也安装对应的CUDA+cudnn版本，并多取一个变量名

  echo $CUDA_HOME
  cd assets/ops/dcn/
  python setup.py build_ext --inplace

再运行python setup.py build_ext --inplace，才不会不会提示CUDA_HOME is not set。其原因如下：

3、[未解决]FileExistsError: [WinError 183] 当文件已存在时，无法创建该文件。: ‘./outputs/workspace\DB’ -> 'workspace’

  File "E:\ZhuoZhuangOCR\Paper\Latest\DB-Resnet\DB\concern\log.py", line 68, in _make_storage
    os.symlink(storage_dir, self.log_dir)
FileExistsError: [WinError 183] 当文件已存在时，无法创建该文件。: './outputs/workspace\\DB' -> 'workspace'

4、将config中的yaml的路径改为绝对路径
