Python Scripting Extension - Release Notes
Version 9.7.0
Release date: Jun 3, 2020
When upgrading RapidMiner Server to version 9.7 or later, you must also update the Python Scripting Extension to version 9.7.
New Features
- As the new repositories support storing arbitrary files, support for dragging and dropping .py and .ipynb files to the canvas has been introduced. RapidMiner Studio will take care of creating the necessary operators.
- Note: no adjustments are made to the code when dragging and dropping, so users still need to take care of creating the rm_main function so the code will get executed properly. A run-time error will be displayed if this is not done.
Enhancements
- Added support for projects, so the rapidminer Python library can function correctly.
Bugfixes
- Optional hidden parameter (
rapidminer.python_scripting.shell_command) added to avoid potential freeze during extension initialization on Linux and macOS(default value:bash -l -i -c)
Version 9.6.0
Release date: Feb 25, 2020
New Features
- Macros are now accessible in Execute Python in an optional dict parameter. Their value can be modified in the script.
Enhancements

Bugfixes
