Serializer for dictionary.
This is the standard serializer in Chainer. The hierarchy of objects are simply mapped to a flat dictionary with keys representing the paths to objects in the hierarchy.
Despite of its name, this serializer DOES NOT serialize the object into external files. It just build a flat dictionary of arrays that can be fed into
numpy.savez_compressed(). If you want to use this serializer directly, you have to manually send a resulting dictionary to one of these functions.
Serializes or deserializes a value by given name.
This operator saves or loads a value by given name.
If this is a serializer, then the value is simply saved at the key. Note that some type information might be missed depending on the implementation (and the target file format).
If this is a deserializer, then the value is loaded by the key. The deserialization differently works on scalars and arrays. For scalars, the
valueargument is used just for determining the type of restored value to be converted, and the converted value is returned. For arrays, the restored elements are directly copied into the
valueargument. String values are treated like scalars.
As of v2.0.0, serializers and deserializers are required to correctly handle the
None, serializers save it in format-dependent ways, and deserializers just return the loaded value. When the saved
Nonevalue is loaded by a deserializer, it should quietly return the
Nonevalue without modifying the
Serialized or deserialized value.
Gets a child serializer.
This operator creates a _child_ serializer represented by the given key.
Parameters: key (str) – Name of the child serializer.
Saves an object by this serializer.
This is equivalent to
Parameters: obj – Target object to be serialized.
