Hi,
how can I install the Python packages and extensions in Knime? Is there a specific way?

@Ol_Broenner you can just install the basic Python extension like any other:

If you want specific packages you can check out my article.

Hi @Ol_Broenner , if installing Python manually, this post shows an example.

Execution failed: Could not connect to the Python process

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 [image] and then made sure that python 3.9 was on the path: [image] In KNIME I set my python folder manually: [image] It complained about numpy and pandas so in a command prompt I executed the following: pip install numpy pip install pandas [image] I created a new workflow and on it placed an Empty Table Creator and a Python Script node. But executing t…

Previously I found that there were problems using python beyond 3.11 because of some deprecated packages that KNIME expected and which were no longer present in Python 3.12 onwards. I don’t know if that is still the case with KNIME 5.5, but worth noting in case you get tripped up by this.

Hi,
thanks for the really fast answers. But the following problem occured by installing the python nodes by drag and drop:
"Could not create provisioning agent: Unable to read repository at https://content.xml/content.xml.
What can I do in this case? What is the easiest way?

Kind regards

Hi @Ol_Broenner , I don’t know why KNIME should be attempting to read the clearly incorrect repository address “https://content.xml/content.xml”.

When you say you installed the python nodes by drag and drop, which specific nodes did you try to drag and drop?

I’d suggest you install them by explicitly installing the “KNIME Python Integration” extension. Is there any particular reason why that’s not an option for you? Or was it that whole extension that you were trying to drag and drop?
