I just upgraded from KNIME 3.6 to 3.7 and I notice that python nodes no longer work correctly. Specifically, all newly added python scripting nodes will only use the python2 executable even if the node is switched to use python3.
For example, if I drag in a new Python Scripting node and run:
I get the path to my python2 executable (as specified in the KNIME preferences):
This is all as expected, however if I then go to the node options and switch from the default Python2 to Python 3 option, Apply, reset the workspace, and run the same code I get the same python2 path as output. Even if I apply, close the config window, re-open the node config, confirm python3 is still specified and run again – the output is the same.
Interestingly, if I run a python scripting node from a workflow last saved under KNIME 3.6 (and previously set to use python3) I get the expected output (my python3 executable as specified in the KNIME preferences):
Any idea on how to get the nodes to use python3 in KNIME 3.7?
