pm4py.read.read_dfg

pm4py.read.read_dfg(file_path: str, encoding: str = 'utf-8') → Tuple[Dict[Tuple[str, str], int], Dict[str, int], Dict[str, int]]

Reads a DFG object from a .dfg file. The DFG object returned is a triple containing the following objects:

1. DFG Object, encoded as a Dict[Tuple[str,str],int], s.t. DFG[('a','b')]=k implies that activity 'a' is directly followed by activity 'b' a total of k times in the log

2. Start activity dictionary, encoded as a Dict[str,int], s.t., S['a']=k implies that activity 'a' is starting k traces in the event log

3. End activity dictionary, encoded as a Dict[str,int], s.t., E['z']=k implies that activity 'z' is ending k traces in the event log.

Return type:

Tuple[Dict[Tuple[str,str],int], Dict[str,int], Dict[str,int]]

Parameters:

• file_path (str) – file path of the dfg model on disk

• encoding (str) – the encoding to be used (default: utf-8)
