Python DT Erreur utilise uniquement avec les valeurs Datetimelike
# Your problem here may be that to_datetime silently failed so the dtype remained as str/object,
# if you set param errors='coerce' then if the conversion fails for any particular string
# then those rows are set to NaT.
df['Date'] = pd.to_datetime(df['Date'], errors='coerce')
