Knime - Python Script none type object has no Attributes as_py

[mlauber71]

@LukeParkes welcome to the KNIME forum. You will have to convert the pandas dataframe (if it is one) back to Arrow before bringing it back to KNIME.

# data from python (pandas) to KNIME
knio.output_tables[0] = knio.Table.from_pandas(sh_w) 

AttributeError NoneType object has no attribute 'to_arrow_table'

@sirabelk3 I think you should make sure you have the latest version of the KNIME Python integration installed or a working Python installation of your own. Also you should check what type of data your code would produce. If you want to bring data back from Python to KNIME you would have to have an Arrow data table. Often you would have a Pandas data frame that you would then convert to Arrow. Maybe check out these examples. https://forum.knime.com/t/help-to-use-python-do-insert-variable-in-sq…
