mmengine.fileio.copyfile_from_local(src, dst, backend_args=None)

Copy a local file src to dst and return the destination file.

If the backend is the instance of LocalBackend, it does the same thing with copyfile().

参数:

• src (str or Path) – A local file to be copied.

• dst (str or Path) – Copy file to dst.

• backend_args (dict, optional) – Arguments to instantiate the corresponding backend. Defaults to None.

返回:

If dst specifies a directory, the file will be copied into dst using the base filename from src.

返回类型:

str
