ich tun Gruppe versuchen, state
Ich benutze
result = df.groupby("state").\
agg({"state": pd.Series.nunique, "duration (seconds)": np.sum}).\
rename(columns={"state": "frequency", "duration (seconds)": "whole time"}).\
reset_index()

. Ich versuche, duration (seconds)
zu konvertieren, aber es gibt duration (seconds)
zurück. Wie kann ich dieses Problem überprüfen?
, was den Fehler tatsächlich ist zu werfen? tut 'Ergebnis = df.groupby (" state "). agg ({" state ": pd.Series.nunique})' Arbeit? (dh, die Hälfte Ihrer groupby) – Stael
wir haben keine Ahnung, woher der Fehler kommt. poost den ganzen Fehler bro –
