[人工智能]Windows不支持PosixPath问题解决

问题描述

之前在Linux环境下训练好了模型，后使用Windows系统加载模型使用报错

解决办法

修改所使用环境下的lib/pathlib.py代码大概1040行的函数：

#修改前
def __new__(cls, *args, **kwargs):
        if cls is Path:
            cls = WindowsPath if os.name == 'nt' else PosixPath
        self = cls._from_parts(args, init=False)
        if not self._flavour.is_supported:
            raise NotImplementedError("cannot instantiate %r on your system"
                                      % (cls.__name__,))
        self._init()
        return self

#修改后    
def __new__(cls, *args, **kwargs):
        if cls is Path:
            # cls = WindowsPath if os.name == 'nt' else PosixPath
            cls = WindowsPath
        self = cls._from_parts(args, init=False)
        # Windows doesn't support PosixPath
        if type(self) == PosixPath:
            cls = WindowsPath
            self = cls._from_parts(args, init=False)
        if not self._flavour.is_supported:
            raise NotImplementedError("cannot instantiate %r on your system"
                                      % (cls.__name__,))
        self._init()
        return self
