Numpy and Pandas (Python 3) in KNIME

[Enigma2018]

Dear all,

I want to run a python script in KNIME but i always get this error:
ERROR Python Script (1⇒1) 2:104 Execute failed: Could not start Python kernel. Error during Python installation test: Library numpy is missing
Library pandas is missing, required minimum version is 0.20.0
. See log for details.

I installed the latest version of python and also of anaconda but in anaconda i can’t install packages because of the firewall.
How can I solve this issue without changing the firewall config.
Thanks in advance

Sounds like this problem:

KNIME desktop (version 3.7.1) - could not start Python kernel

Hi @Gaurav_Yadav, you are missing some packages, take a look at this guide on how to fully set up the python extension: https://www.knime.com/blog/setting-up-the-knime-python-extension-revisited-for-python-30-and-20 best, Gabriel

The solution should be to stick to a compatible version of Python.

Hi Enigma2018,

@Enigma2018

I installed the latest version of python and also of anaconda but in anaconda i can’t install packages because of the firewall.

Maybe setting up a proxy could help. See, e.g., here or here.

I solved this problem by pip installing the dependencies.

thanks @mlauber71 and @MarcelW
