Re: [HTCondor-users] How to get htcondor2 bindings using pip install?

[Jeff Templon <templon@xxxxxxxxx>]

Hi All,

I realised later why I couldnât get the rrdtool bindings to work under uv.  I repaired that (yum install rrdtool-devel) and then running under a uv-managed script yields joy.  Thanks for all your help.

$ head gv-dbupdate

#!/usr/bin/env -S uv run --script

#

# /// script

# requires-python = ">=3.14"

# dependencies = [

#     "htcondor",

#     "rrdtool",

# ]

# ///

For PyPI, we build for the oldest version available in the manylinux platform. So, htcondor2 is available for Python 3.8 and newer from PyPI.

So, on Rocky 8 you can either install a newer version of Python (AppStream has python38, python39, python3.11, and python 3.12) or you can use the Python bindings in python3-condor-25.2.1

So yes, old htcondor.  Any idea why it canât find the newer ones?  Is there some python version requirement on newer releases?   Iâm on rocky 8 so the python release is pretty old - 3.6.8

that, I could say âimport htcondor2â and it worked.  NOW, using just pip, and pip install htcondor, I can only do âimport htcondorâ - âimport htcondor2â DOES NOT WORK so neither would import htcondor2 as htcondor.

That strongly implies that you're installing a rather old version of the htcondor package --
