booldog.utils.misc

Attributes

Create a collection of name/value pairs.

`ensure_ndarray`(v)	Return numpy array of v, given array, int/float, list, tuple
`parameter_to_array`(parameter, graph_keys)	Parameter argument to numpy array
`file_writable`(path)	Checks if path is writeable. If not, attempts to provide reason, and raises
`get_pkg_version`()	Get version of booldog package

class booldog.utils.misc.ExtendedEnum(*args, **kwds)

Bases: enum.Enum

Create a collection of name/value pairs.

Example enumeration:

>>> class Color(Enum):
...     RED = 1
...     BLUE = 2
...     GREEN = 3

Access them by:

Enumerations can be iterated over, and know how many members they have:

>>> len(Color)
3

>>> list(Color)
[<Color.RED: 1>, <Color.BLUE: 2>, <Color.GREEN: 3>]

Methods can be added to enumerations, and members can have their own attributes – see the documentation for details.

booldog.utils.misc.ensure_ndarray(v): Return numpy array of v, given array, int/float, list, tuple

booldog.utils.misc.parameter_to_array(parameter, graph_keys)

Parameter argument to numpy array

Parameters:

parameter (array, int, float or dict) –

if array:
make sure length is n

if int or float:
return an array of length n with value

if dict:
returns an array of length n with values set according to

keys (nodes indexed by graph_keys), and the rest set to ‘default’ key
graph_keys (dict)

Returns:

parameter_array – array of length n

Return type:

numpy array

booldog.utils.misc.file_writable(path)

Checks if path is writeable. If not, attempts to provide reason, and raises an Exception.

Parameters:: path (str or Path) – Path to file to check for writability. If the file does not exist, the function will check if it can be created.
Return type:: None

booldog.utils.misc.get_pkg_version()

Get version of booldog package
