PNDSPY1003

Element is not recognized

Message: < element > is not recognized, Pandas element is not recognized yet.

Category: Conversion error.

Description

This issue appears when there is a Pandas element that is not yet recognized by the SMA.

Scenarios

This issue can occur for different reasons, such as:

An element that does not exist in Pandas.
An element that was added in a Pandas version that the SMA does not yet support.
An internal error of the SMA when processing the element.

Scenario 1

Input

Below is an example of an element that does not exist in Pandas.

import pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

df.non_existent_function()

Output

Since the element does not exist in Pandas, the tool adds the EWI on the output code.

import snowflake.snowpark.modin.pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

#EWI: PNDSPY1003 => pandas.core.frame.DataFrame.non_existent_function is not yet recognized
df.non_existent_function()

Recommended fix

If it is not a valid Pandas element removed and use a valid Pandas function.

import snowflake.snowpark.modin.pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

df.valid_existent_function()

Scenario 2

Input

Below is an example of an element that was added in a Pandas version that the SMA does not yet support.

import pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

df.valid_function_since_x.x.x_version()

Output

Since the element was added in a Pandas version that the tool does not support yet, the tool adds the EWI on the output code.

import snowflake.snowpark.modin.pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

#EWI: PNDSPY1003 => pandas.core.frame.DataFrame.valid_function_since_x.x.x_version is not yet recognized
df.valid_function_since_x.x.x_version()

Recommended fix

Scenario 3

Input

Below is an example of an internal error of the SMA when processing the element.

import pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

df.valid_function()

Output

If it was an error while processing the element and that cause the tool can't recognize, the tool adds the EWI on the output code.

import snowflake.snowpark.modin.pandas as pd

df = pd.DataFrame(
    {
        "Name": ["Alice", "Bob", "Charlie"],
        "Age": [25, 30, 35],
        "City": ["New York", "Los Angeles", "Chicago"],
    }
)

#EWI: PNDSPY1003 => pandas.core.frame.DataFrame.valid_function is not yet recognized
df.valid_function()

Recommended fix
