alibi.saving module

class alibi.saving.NumpyEncoder(*, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=True, sort_keys=False, indent=None, separators=None, default=None)[source]

Bases: json.encoder.JSONEncoder

default(obj)[source]

Implement this method in a subclass such that it returns a serializable object for o, or calls the base implementation (to raise a TypeError).

For example, to support arbitrary iterators, you could implement default like this:

def default(self, o):
    try:
        iterable = iter(o)
    except TypeError:
        pass
    else:
        return list(iterable)
    # Let the base class default method raise the TypeError
    return JSONEncoder.default(self, o)
alibi.saving.load_explainer(path, predictor)[source]

Load an explainer from disk.

Parameters
  • path (Union[str, PathLike]) – Path to a directory containing the saved explainer.

  • predictor – Model or prediction function used to originally initialize the explainer.

Return type

Explainer

Returns

An explainer instance.

alibi.saving.save_explainer(explainer, path)[source]

Save an explainer to disk. Uses the dill module.

Parameters
  • explainer (Explainer) – Explainer instance to save to disk.

  • path (Union[str, PathLike]) – Path to a directory. A new directory will be created if one does not exist.

Return type

None
