PNDSPY1016

Message pandas.core.series.Series.interpolate 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.interpolate usage. Snowpark pandas currently has limitations with Series.interpolate. It isn’t supported if axis == 1, limit is set, limit_area is “outside”, or method isn’t “linear”, “bfill”, “backfill”, “ffill”, or “pad”. Also, limit_area=”inside” is supported only when method is linear.

Scenario

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

Input

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

import pandas as pd
import numpy as np

s = pd.Series([0, 2, np.nan, 8])
s.interpolate(method='polynomial', order=2)

Output

The SMA adds the EWI PNDSPY1016 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([(0.0, np.nan, -1.0, 1.0),
                   (np.nan, 2.0, np.nan, np.nan),
                   (2.0, 3.0, np.nan, 9.0),
                   (np.nan, 4.0, -4.0, 16.0)],
                  columns=list('abcd'))
#EWI: PNDSPY1016 => pandas.core.series.Series.interpolate is not support if axis == 1, limit is set, limit_area is "outside", or method is not "linear", "bfill", "backfill", "ffill", or "pad". And limit_area="inside" is supported only when method is linear. Check Snowpark pandas documentation for more detail.
