报错内容

raise NotImplementedError(“cannot instantiate %r on your system”
NotImplementedError: cannot instantiate ‘PosixPath’ on your system’‘’

报错原因：

模型在linux训练后windows路径加载错误(路径错误问题)

解决方案1：在调用PosixPath时修改

1. windows系统读取时，报错：NotImplementedError: cannot instantiate ‘PosixPath’ on your system
   在代码的最前面加上：

import pathlib
temp = pathlib.PosixPath
pathlib.PosixPath = pathlib.WindowsPath

2. Linux系统读取时，报错：NotImplementedError: cannot instantiate ‘WindowsPath’ on your system
   在代码的最前面加上：

import pathlib
pathlib.WindowsPath = pathlib.PosixPath

解决方案2：修改…\anaconda3\envs\ADP\lib\pathlib.py文件

 def __new__(cls, *args, **kwargs):
        if cls is Path:
            cls = WindowsPath if os.name == 'nt' else PosixPath
        self = cls._from_parts(args)
 		
 		#添加代码
        if type(self) == PosixPath:
            cls = WindowsPath
            self = cls._from_parts(args)

        if not self._flavour.is_supported:
            raise NotImplementedError("cannot instantiate %r on your system"
                                      % (cls.__name__,))
        return self
