PNDSPY1194¶

Message Pandas < pandas.core.series.Series.nsmallest > has a partial mapping with a few scenarios not supported in Snowpark.

Category Warning

Description¶

This issue appears when the SMA detects the use of a pandas element that has a direct equivalent in Snowpark pandas, but some scenarios might behave differently than pandas.

Reason: N if keep == “all”.

Scenario¶

A method with a few scenarios that aren’t supported in Snowpark.

Input¶

The following example shows a method with a few unsupported scenarios in Snowpark.

import pandas as pd

s = pd.Series([1, 2, 3, 4, 5])
result = s.nsmallest()

Copy

Output¶

The SMA adds the EWI PNDSPY1194 to the output code to let you know that this element has a few scenarios that aren’t supported in Snowpark.

import snowflake.snowpark.modin.pandas as pd

#EWI: PNDSPY1194 => pandas.core.series.Series.nsmallest has a partial mapping, with few scenarios not supported. Check Snowpark pandas documentation for more detail.
s = pd.Series([1, 2, 3, 4, 5])
result = s.nsmallest()

Copy

Recommended fix¶

Behavioral note: N if keep == “all”.

This behavior may differ from native pandas. Recommended actions:

Test with a representative sample of your data
Compare results with native pandas if precision is critical
Use .to_pandas() if exact pandas behavior is required

Additional recommendations¶

Check the Snowpark pandas documentation to verify which scenarios aren’t supported for that specific element.
