alpha miner factory not compatible with data frame

[s-j-v-zelst]

Alpha miner factory is not compatible when a data frame is given. In such a case, the variant is ignored (plus versus classical), i.e., the classical version is always called.

Thanks for signaling!

Seemingly debunked too.

Placing an "AAAA" inside the factory of the Alpha Miner, when the dataframe is checked, and using the following script:

from pm4py.objects.log.adapters.pandas import csv_import_adapter from pm4py.algo.discovery.alpha import factory as alpha_miner

df = csv_import_adapter.import_dataframe_from_path("C:\running-example.csv") print(type(df)) alpha_miner.apply(df)

I got:

<class 'pandas.core.frame.DataFrame'> AAAA

That is not the problem I was referring to. The problem is the following:

if isinstance(log, pandas.core.frame.DataFrame):
    dfg = df_statistics.get_dfg_graph(log, case_id_glue=parameters[pmutil.constants.PARAMETER_CONSTANT_CASEID_KEY],
                                      activity_key=parameters[pmutil.constants.PARAMETER_CONSTANT_ACTIVITY_KEY],
                                      timestamp_key=parameters[pmutil.constants.PARAMETER_CONSTANT_TIMESTAMP_KEY])
    return VERSIONS_DFG[variant](dfg, parameters=parameters)

The factory will use the DFG only version, for which the PLUS version is undefined.

If this is for performance reasons, I propose to do the following: When we have a dataframe and the version is classic, use the DFG only, if the version is PLUS, we use a converter and then route to the PLUS
