Hi All

I am not able to use jinja2 in my python code getting below error:

Executing the Python script failed: Traceback (most recent call last):
File “”, line 3, in
ModuleNotFoundError: No module named ‘jinja2’

I have already installed this and below is the version not sure why I am still getting this error, any suggestion would be really helpful for me

(base) C:\Users\a-mmj>pip show jinja2

Name: Jinja2

Version: 3.1.2

Summary: A very fast and expressive template engine.

Hi @madhumita3,

you are saying that you have jinja2 installed via pip already.
According to this line

(base) C:\Users\a-mmj>pip show jinja2

you have installed it in the base environment.
Please check which environment you use for your Python Script node (in the KNIME Analytics Platform via Preferences -> KNIME -> Python). If the radio button is set to bundled, you need to create a new environment like this in your terminal:

conda create --name my_python_env -c knime -c conda-forge knime-python-scripting=5.2 python=3.11

Then you can

conda activate my_python_env

and

pip install jinja2

Then in the preferences, select that environment.

That way, you

1. ensure that you have a Python environment, which has the packages necessary for KNIME (knime-python-scripting) and your pip packages (jinja2) and
2. ensure that the Python Script nodes use exactly that environment

Does that help?

Thank you Steffen for your solution and it worked for me.
