Während ich diese bestimmte Codezeile ausführe, wird die Fehlermeldung angezeigt, dass eine bestimmte Spalte mit dem String-Datentyp in numerische Werte konvertiert werden muss

Code: Select all

data['sex'] = data['sex'].map( {'male': 1, 'female': 0} ).astype("int64")
Fehlermeldung

Code: Select all

Ich muss es in kategoriale Werte umwandeln
Wer die Lösung kennt, bitte helfen Sie mir
