param.parameterized.Parameters.deserialize_parameters

Parameters.deserialize_parameters(serialization, subset=None, mode='json') → dict

Deserialize the given serialized data. This data can be used to create a Parameterized object or update the parameters of an existing Parameterized object.

Parameters:

• serialization (str) – The serialized parameter data as a JSON string.

• subset (list of str, optional) – A list of parameter names to deserialize. If None, all parameters will be deserialized. Defaults to None.

• mode (str, optional) – The serialization format. By default, only ‘json’ is supported. Defaults to ‘json’.

Returns:

• dict – A dictionary with parameter names as keys and deserialized values.

Examples

>>> import param
>>> class P(param.Parameterized):
...     a = param.Number()
...     b = param.String()
...
>>> serialized_data = '{"a": 1, "b": "hello"}'
>>> deserialized_data = P.param.deserialize_parameters(serialized_data)
>>> print(deserialized_data)
{'a': 1, 'b': 'hello'}
>>> instance = P(**deserialized_data)
