I’m facing a problem with Python Script node that I’ve never encountered before while creating dataframes.
I’m trying to convert the input table to Pandas dataframe as shown below:
If you are working with KNIME Analytics Platform and using its Python integration, the correct way to create a Pandas DataFrame from an input table and then assign it back as an output table is indeed as you described:
Convert the first input table to a Pandas DataFrame:
df = knio.input_tables[0].to_pandas()
After processing your DataFrame, convert it back to a KNIME table and assign it to an output slot:
This approach uses KNIME’s Python integration (knio) to interchange data between KNIME and Pandas, which is efficient for data processing within KNIME workflows using Python.
