Hi,

Is there a way to upgrade the current Python version in the bundled package (from 3.11 to 3.13 for ex.)?

```auto
C:\Users\...\AppData\Local\Programs\KNIME\bundling\org_knime_pythonscripting_channel_bin_5.8.3\.pixi\envs\default>python.exe
Python 3.11.13 | packaged by conda-forge | (main, Jun 4 2025, 14:39:58) [MSC v.1943 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

```

I’m currently running “KNIME 5.8.3 LTS”.  
Thanks

@pierrelouis I think the integrated Python version is tied to a specific KNIME version since some nodes might depend on precise packages. But you can always create your own Python environments with the packages you need:

> [@Support for Python 3.12](https://forum.knime.com/t/support-for-python-3-12/90643/10):
>
> @waterman you could define a simple yaml file with ‘boundaries’ for KNIME compatibility like python\<3.12 and knime-python-base\<=5.9 and then add you package as coda-forge package or pip. In this example in the place of vtreat. Or just at the end right before pip. Conda will then create a complete list of packages that you could then install separately. name: py311\_knime # Name of the created environment channels: # Repositories to search for packages - conda-forge - knim…

Thanks @mlauber71!  
Obviously, I add the “custom package” option in mind but I was wondering if something easier was possible ^^
