torch.utils.model_zoo.load_url(url, model_dir=None, map_location=None)[source]

Loads the Torch serialized object at the given URL.

If the object is already present in model_dir, it’s deserialized and returned. The filename part of the URL should follow the naming convention filename-<sha256>.ext where <sha256> is the first eight or more digits of the SHA256 hash of the contents of the file. The hash is used to ensure unique names and to verify the contents of the file.

The default value of model_dir is $TORCH_HOME/models where $TORCH_HOME defaults to ~/.torch. The default directory can be overriden with the $TORCH_MODEL_ZOO environment variable.

  • url (string) – URL of the object to download
  • model_dir (string, optional) – directory in which to save the object
  • map_location (optional) – a function or a dict specifying how to remap storage locations (see torch.load)
