PNDSPY1002

Element has a partial mapping but there are a few scenarios not supported in Snowpark.

Message: Pandas < element > 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.

Scenario

Input

Below is an example of a method with a few scenarios not supported in Snowpark.

import pandas as pd

pd.melt(df, id_vars=['A'], value_vars=['B'])

Output

The SMA adds the EWI PNDSPY1002 on the output code to let you know that this element has a few scenarios not supported in Snowpark.

import snowflake.snowpark.modin.pandas as pd

#EWI: PNDSPY1002 => pandas.core.reshape.melt.melt has a partial mapping, with few scenarios not supported. Check Snowpark Pandas documentation for more detail.
pd.melt(df, id_vars=['A'], value_vars=['B'])

Recommended fix

Since this is a generic error code that applies to a range of partial supported functions, there is not a single and specific fix. The appropriate action will depend on the particular element in use.

Please note that even though the element is not supported in a few scenarios, it does not necessarily mean that a solution or workaround cannot be found. It only means that the SMA itself cannot find the solution.

Additional recommendations

• Check the Snowpark Pandas documentation to verify which scenarios are not supported for that specific element.
• For more support, you can email us at [e-mail] or post an issue in the SMA. If you have a contract for support with Snowflake, reach out to your sales engineer, and they can direct your support needs.
