Python script starting for a long time

[Doosheck]

Hello there!

I am having problems when working with a python script in KNIME. I have set up a new conda environment using knime, so it has all the required packages. When I double click the Python Script node, I get the information “Starting Python…”, which stays there without an end. Does anyone have the idea what the reason might be?

Hello @Doosheck ,

Which version of KNIME AP are you using?
Also, could you please share the log file?

Thanks,
Sanket

additionally to @sanket_2012 s questions: is the node connected to a previous node?

Hello @Doosheck

You may find a possible solution in this recent post; the scripting of input/output port reference, changed from deprecated nodes.

Python Script Execute failed: Could not connect to the Python process.

Hello @alfroc You are right; the Py coding for referencing data input from KNIME to pandas, and sending it to the output port changed from legacy nodes. You can test with the following code as starting point: import knime.scripting.io as knio import pandas as pd # data in df = knio.input_tables[0].to_pandas() # things happen print(type(df)) # output as pd.DataFrame knio.output_tables[0] = knio.Table.from_pandas(df) BR PS.- The equivalent code for your Py code example would be: import kn…
