Ptyhon Scripting Integration for KNIME version 4.1.1.v202012070647 by Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG)

This node opens a local Python session and pushes the data table from KNIME into Python. Depending on the preference settings under KNIME > Community Scripting > Python Scripting the node either

  • starts Python via command line and executes the Python script to load KNIME tables into Python as pandas dataframe.
  • Otherwise Jupyter is started which loads a notebook to load the KNIME data.

The input data table is sent to Python as a pandas data frame named "kIn". If the optional input ports are used then data frames are named "kIn1", "kIn2" and "kIn3".
