Functions

sampo.userinput.parser.general_build.break_loops_in_input_graph(works_info: pandas.DataFrame) → pandas.DataFrame

Eliminate all cycles in received work graph. Algo breaks cycle by removing edge with the lowest weight (e.x. frequency of occurrence of the link in historical data).

Parameters:

works_info – given work info

Returns:

work info without cycles

sampo.userinput.parser.general_build.fix_df_column_with_arrays(column: pandas.Series, cast: Callable[[str], Any] | None = str, none_elem: Any | None = NONE_ELEM) → pandas.Series

sampo.userinput.parser.general_build.preprocess_graph_df(frame: pandas.DataFrame) → pandas.DataFrame

sampo.userinput.parser.general_build.add_graph_info(frame: pandas.DataFrame) → pandas.DataFrame

sampo.userinput.parser.general_build.topsort_graph_df(frame: pandas.DataFrame) → pandas.DataFrame

Sort DataFrame of works in topological order

Parameters:

frame – DataFrame of works

Returns:

topologically sorted DataFrame

sampo.userinput.parser.general_build.build_work_graph(frame: pandas.DataFrame, resource_names: list[str]) → sampo.schemas.graph.WorkGraph

sampo.userinput.parser.general_build.get_graph_contractors(path: str, contractor_name: str | None = 'ООО "***"')
