Python Execute Pickle Table

Basic Information

Description	This node is used to execute python pickle on a process table
Input	One process table and one python pickle
Output	One table
Usage Tags	PYTHON , TRANSFORMATION , PICKLE

Node Settings

Input Table ( string, required) : Name of a process input table.
Pickle (string, required) : Name of pickle object that will be used.
Function (string, required) : Name of pickle function that will be used.
Output Table (string, required) : Name of output table that will be generated.

This node can only be used on a pickle objects and functions that takes single pandas DataFrame as input and returns again single pandas DataFrame.

Tips and Advanced usage

Similar functionality can be used with Python Script Node, but pickle objects allows for more complex use cases, where an entire trained model can be encoded as a pickel object and prediction function can be used afterwards.

Examples

Example 1
