PNDSPY1014

Message pandas.core.series.Series.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.series.Series.aggregate usage. Snowpark pandas currently has limitations with Series.aggregate. Check Supported Aggregation Functions for a list of supported functions.

Scenario

An unsupported use of pandas.core.series.Series.aggregate.

Input

The following example shows an unsupported use of pandas.core.series.Series.aggregate.

import pandas as pd
import numpy as np

s = pd.Series([1, 2, 3, 4])
s.aggregate(['min', 'max'])

Output

The SMA adds the EWI PNDSPY1014 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: PNDSPY1014 => pandas.core.series.Series.aggregate does not support some combinations of parameters for specific aggregate functions. Check Snowpark pandas documentation for more detail.
df.aggregate(['sum', 'min'])

Since this is an error that applies to a range of partially supported aggregate functions, no specific fix applies to all cases. The appropriate action depends on the particular aggregate function in use.

Even though the element isn’t supported in some scenarios, you might still find a solution or workaround. This issue code only means that the SMA can’t convert the element automatically.
