Parameters
----------
graph : networkx.DiGraph.
networkx.DiGraph. Can be build from a transition matrix (numpy matrix/array) using networkx.from_numpy_matrix.
source : int.
Starting node for all paths
target : list (dtype=int).
List of nodes at which the paths can end.
edge_attr : str.
Edge attribute that is used to build transition matrix. Only use 'weight' if it's an explicitly defined edge
attribute, otherwise networkx will build an adjacency matrix instead of a transition matrix.
normalize : bool.
If True, normalize each path probability by the sum of all probabilities, so they sum to 1.
rm_diag : bool.
If True, the matrix diagonal, i.e. the probability of self-looping, is set to 0. This will skew the path
probabilities.
Returns
-------
path_probs : dict.
Dictionary with paths (dtype=tuple) as dict. keys and probabilities as dict. values.
