PNDSPY1013

Message pandas.core.frame.DataFrame.aggregate has a partial mapping because there is a not supported scenario in Snowpark pandas.

Category Warning

Description

This issue appears when the SMA identifies a pandas.core.frame.DataFrame.aggregate usage. Snowpark pandas currently has limitations with DataFrame.aggregate. Check Supported Aggregation Functions for a list of supported functions.

Scenario

An unsupported use of pandas.core.frame.DataFrame.aggregate.

Input

The following example shows an unsupported use of pandas.core.frame.DataFrame.aggregate.

import pandas as pd
import numpy as np

df = pd.DataFrame([[1, 2, 3],
                       [4, 5, 6],
                       [7, 8, 9],
                       [np.nan, np.nan, np.nan]],
                      columns=['A', 'B', 'C'])
df.aggregate(['sum', 'min'])

Output

The SMA adds the EWI PNDSPY1013 to the output code to indicate that it has a scenario not supported in Snowpark pandas.

from snowflake.snowpark.modin import plugin
import modin.pandas as pd
import numpy as np

df = pd.DataFrame([[1, 2, 3],
                       [4, 5, 6],
                       [7, 8, 9],
                       [np.nan, np.nan, np.nan]],
                      columns=['A', 'B', 'C'])
#EWI: PNDSPY1013 => pandas.core.frame.DataFrame.aggregate does not support some combinations of parameters for specific aggregate functions. Check Snowpark pandas documentation for more detail.
df.aggregate(['sum', 'min'])
