FloatNorm

class auglib.observe.FloatNorm(mean, std, *, minimum=None, maximum=None)[source]

Draw floating point numbers from a normal (Gaussian) distribution.

Parameters

Examples

>>> import auglib
>>> auglib.seed(1)
>>> o = FloatNorm(mean=0.0, std=1.0, minimum=0.0)
>>> round(o(), 2)
1.62
>>> round(o(), 2)
0.87

__call__()

FloatNorm.__call__()[source]

Observe next float value.

Return type

float

Returns

float value

arguments

FloatNorm.arguments

Returns arguments that are serialized.

Returns

Dictionary of arguments and their values.

Raises

RuntimeError – if arguments are found that are not assigned to attributes of the same name

Examples

>>> import audobject.testing
>>> o = audobject.testing.TestObject('test', point=(1, 1))
>>> o.arguments
{'name': 'test', 'point': (1, 1)}

borrowed_arguments

FloatNorm.borrowed_arguments

Returns borrowed arguments.

Returns

Dictionary with borrowed arguments.

from_dict()

static FloatNorm.from_dict(d, root=None, **kwargs)
Return type

audobject.core.object.Object

from_yaml()

static FloatNorm.from_yaml(path_or_stream, **kwargs)
Return type

audobject.core.object.Object

from_yaml_s()

static FloatNorm.from_yaml_s(yaml_string, **kwargs)
Return type

audobject.core.object.Object

hidden_arguments

FloatNorm.hidden_arguments

Returns hidden arguments.

Returns

List with names of hidden arguments.

id

FloatNorm.id

Object identifier.

The ID of an object ID is created from its non-hidden arguments.

Returns

object identifier

Examples

>>> class Foo(Object):
...    def __init__(self, bar: str):
...        self.bar = bar
>>> foo1 = Foo('I am unique!')
>>> foo1.id
'893df240-babe-d796-cdf1-c436171b7a96'
>>> foo2 = Foo('I am different!')
>>> foo2.id
'9303f2a5-bfc9-e5ff-0ffa-a9846e2d2190'
>>> foo3 = Foo('I am unique!')
>>> foo1.id == foo3.id
True

is_loaded_from_dict

FloatNorm.is_loaded_from_dict

Check if object was loaded from a dictionary.

Returns True if object was initialized from a dictionary, e.g. after loading it from a YAML file.

Returns

True if object was loaded from a dictionary,

otherwise False

resolvers

FloatNorm.resolvers

Return resolvers.

Returns

Dictionary with resolvers.

short_id

FloatNorm.short_id

Short object identifier.

The short ID consists of eight characters and is created from its non-hidden arguments.

Returns

short object identifier

Examples

>>> class Foo(Object):
...    def __init__(self, bar: str):
...        self.bar = bar
>>> foo1 = Foo('I am unique!')
>>> foo1.id
'893df240-babe-d796-cdf1-c436171b7a96'
>>> foo1.short_id
'171b7a96'
>>> foo2 = Foo('I am different!')
>>> foo2.short_id
'6e2d2190'
>>> foo3 = Foo('I am unique!')
>>> foo1.short_id == foo3.short_id
True

to_dict()

FloatNorm.to_dict(*, include_version=True, flatten=False, root=None)

Converts object to a dictionary.

Includes items from audobject.Object.arguments. If an argument has a resolver, its value is encoded. Usually, the object can be re-instantiated using audobject.Object.from_dict(). However, if flatten=True, this is not possible.

Parameters

  • include_version (bool) – add version to class name

  • flatten (bool) – flatten the dictionary

  • root (typing.Optional[str]) – if file is written to disk, set to target directory

Return type

typing.Dict[str, typing.Union[bool, datetime.datetime, dict, float, int, list, None, str]]

Returns

dictionary that represent the object

Examples

>>> import audobject.testing
>>> o = audobject.testing.TestObject('test', point=(1, 1))
>>> o.to_dict(include_version=False)
{'$audobject.core.testing.TestObject': {'name': 'test', 'point': [1, 1]}}
>>> o.to_dict(flatten=True)
{'name': 'test', 'point.0': 1, 'point.1': 1}

to_yaml()

FloatNorm.to_yaml(path_or_stream, *, include_version=True)

Save object to YAML file.

Parameters

to_yaml_s()

FloatNorm.to_yaml_s(*, include_version=True)

Convert object to YAML string.

Parameters

include_version (bool) – add version to class name

Return type

str

Returns

YAML string

Examples

>>> import audobject.testing
>>> o = audobject.testing.TestObject('test', point=(1, 1))
>>> print(o.to_yaml_s(include_version=False))
$audobject.core.testing.TestObject:
  name: test
  point:
  - 1
  - 1
