 def import_image(self, src=None, repository=None, tag=None, image=None, changes=None, stream_src=False):
 """ Import an image. Similar to the ``docker import`` command. If ``src`` is a string or unicode string, it will first be treated as a path to a tarball on the local system. If there is an error reading from that file, ``src`` will be treated as a URL instead to fetch the image from. You can also pass an open file handle as ``src``, in which case the data will be read from that file. If ``src`` is unset but ``image`` is set, the ``image`` parameter will be taken as the name of an existing image to import from. Args: src (str or file):
 Path to tarfile, URL, or file-like object repository (str):
 The repository to create tag (str):
 The tag to apply image (str):
 Use another image like the ``FROM`` Dockerfile parameter """
