Using diffent python version in external lookup

Marvin_Janzen — Wed, 02 Jul 2025 11:59:54 GMT

Hello,

I am trying to use a different python version for my external lookup. The global version is 3.7 and my custom one is 3.10

my /opt/splunk/bin contains both 3.7 and 3.10

In my transforms.conf i changed the python version:

[externallookup]

python.version = python3.10

However I am getting the following error:

When I use

[externallookup]

python.version = python3.7

, it does not give the error. Also I am able to use the new python version, when I change the symlink from 3.7 to my 3.10 (for debugging)

But why doesnt it work when I set the python.version to pyhon.3.10?

Thanks in advance!

python.version = python3.10 is not a valid setting. Allowed values are default, python3, python3.7, or python3.9. I don't know how you were able to add Python 3.10 to Splunk, but doing so does not change the validation of python.version settings. I strongly recommend using only the versions of Python that ship with Splunk (3.7 or 3.9).
