Image Output with Python Script

This workflow shows how to use the Python Visualization packages to output images using the Python Script node.

In this workflow, a scatter plot between 'Sepal Width vs Sepal Length' for the Iris dataset is visualized using the Seaborn package, a Sine Wave is visualized using the Matplotlib package and PIL package is used to load pre-existing image from the workflow data folder.


Configure Python Script node for image outputThe Python Script node can be provided with input table or object and it can output a table, object or an imagebased on the user's selection of portsStep 1: Drag the Python Script node to KNIME Analytics PlatformStep 2: Click on the three dots on the node to add an image output portStep 3: Write your script in the "Script" tab and press "execute script" to check if the execution was successful. Seaborn Package Matplotlib Package PIL Package Adopting Python Bundled Packages : Download and open this workflow to auto-install requirements and execute the Python scripts. This workflowuses a node from KNIME Python Integration, which installs Python and a number of pre-defined packages onyour system. Supported on KNIME Analytics Platform 4.7 or higher.
