Hi everyone.
I have an issue with python node. It doesn’t work. I’ve changed python version, conda version, new environment, knime python in manual with path but nothing works.
It happens with two different computers, and I don’t know how I could continue… I don’t want to use python legacy node.
In another computer with and older version of knime (5.2.0), I can run normally python nodes.
Knime 5.2.3
Python 3.9
Hi @sahernandezg , welcome to the KNIME Community!
Can you expand a little on “doesn’t work”…
[edit: I had asked if you have an error message but I just realised that you have included the error message in the post title ;-)]
Also can you tell us which python node you are referring to, as there are a number of them depending on what extensions you have installed?
Do you mean “Python Script” node?
Sorry.
In fact the error that I’m getting in the Python Script node is 
Execution failed: Could not connect to the Python process.
The only way to make it “works” is setting the Python configuration in knime to Bundle buuuuuut I need to use a library that is not in bundle python environment.
@sahernandezg have you configured the nodes to use your specific conda environment
If you are setting up a manual environment…
To test this out, I installed python 3.9 into a folder as follows:
c:\apps\python39
and then made sure that python 3.9 was on the path:
In KNIME I set my python folder manually:
It complained about numpy and pandas
so in a command prompt I executed the following:
pip install numpy
pip install pandas
I created a new workflow and on it placed an Empty Table Creator and a Python Script node.
But executing the workflow resulted in the error you are seeing:
So, I waved a magic wand, and produced this script 
out of nowhere* 
:
pip install beautifulsoup4
pip install cloudpickle
pip install ipython
pip install matplotlib-base
pip install markdown
pip install nbformat
pip install nltk
pip install nomkl
pip install numpy
pip install openpyxl
pip install pandas
pip install pillow
pip install plotly
pip install py4j
pip install pyarrow
pip install python
pip install python-dateutil
pip install pytz
pip install pyyaml
pip install requests
pip install scikit-learn
pip install scipy
pip install seaborn
pip install statsmodels
and executed that in a command prompt. And when that was done…
Thanks a lot! I even tried creating a new environment with “all knime requirements” but nothing…
You saved me! Have a nice day!
