Dist

class liesel.model.nodes.Dist(distribution, *inputs, _name='', _needs_seed=False, **kwinputs)

Bases: Node

A distribution node.

Methods

all_input_nodes()	Returns all non-keyword and keyword input nodes as a unique tuple.
all_output_nodes()	Returns all output nodes as a unique tuple.
clear_state()	Clears the state of the node.
flag_outdated()	Flags the node and its recursive outputs as outdated.
init_dist()	Initializes the distribution.
set_inputs(*inputs, **kwinputs)	Sets the non-keyword and keyword input nodes.
update()	Updates the value of the node.
