Problem of Datetime error in streamlit

Ask the community or our support engineers for answers to questions.
i am using streamlit 0.72 and python 3.6.9 in linux 18.04

i have code running in Jupyter Notebook/Lab which was ok.
however, when i Copy it to streamlit , it always pop 2 error
1)Can only use .dt accessor with datetimelike values
2)‘NoneType’ object has no attribute ‘total_seconds’

Problem is
whenever i encounter (1),
i need to run
df[‘time’] = pd.to_datetime(df[‘time’]),
however, once i added to this,
(2) several line will run error
will appear following error and this would not be happen in Jupyter lab/notebook
“AttributeError: ‘NoneType’ object has no attribute ‘total_seconds’”

a) new_df = df.groupby([df[‘time’]])[‘use’].max().reset_index()
b) chart plot
c) st.write(df)

and from google i have reach timezone problem but it cant solve my case for settting UTC timezone
and in few try But not 100% guaurantee to resolve is that
i need to format my datetime
df[‘time’] = pd.to_datetime(df[‘time’] ,errors = ‘coerce’,format = ‘%Y-%m-%d %H’).dt.strftime("%Y-%m-%d %H")

The error was
AttributeError: ‘NoneType’ object has no attribute ‘total_seconds’

I have the same problem. Can you solve it?
