两个问题:(1)在决定检查os.path.exists之前,您需要检查OSError的子错误条件——请参见stackoverflow.com/a/5032238/763269,(2)在os.path.exists上的成功并不意味着目录存在,而只是路径存在——可以是文件、符号链接或其他文件系统对象。 Check if a directory exists and create it if necessary? 直接的答案是,...

In the example above, you instantiate a Path object and create the file using .touch(). You use .exists() both to verify that the file didn’t exist before and then to check that it was successfully created. If you use .touch() again, then it updates the file’s modification time....
问pathlib:无法从“collections”导入名称“Sequence”EN这是因为在 sktime 依赖项中使用了来自 sklearn 的私有方法。由于 sklearn 更新为 1.1.0，这个私有方法被删除/移动，因此它正在崩溃。sktime 团队正在努力解决这个问题。同时，您可以通过强制安装 sklearn 1.0.2 来修复此问题。
If the path exists, it outputsTrue; else, it returnsFalse. You can also check if a path is a file or directory: print(path.is_file()) print(path.is_dir()) Output >>> False True Note: An object of thePathclass creates a concrete path for your operating system. But you can also...
