I have a database with two columns: name (str) and probability (float).
I am running this command:
df[['name','probability']].groupby('name').prod()
on a Databricks (runtime 7.3) notebook and df is a koalas dataframe.
The error I get is:
PandasNotImplementedError: The method `pd.groupby.GroupBy.prod()` is not implemented yet.
I wonder if there is a workaround.
