    Hi Mathieu,
    
    Could it be that you have different python versions on your
    machine?  I noticed your script using "python3" from your path, but
    your venv was created running "python".
    
    What is the output from the following commands:
    
      python3 --version
        /usr/bin/env python3 --version
        python --version
    
    FWIW, I just tested your script above on fresh Alma9 install (in a
    container) using the system package HTCondor v 23.0.10 fetched from
    get.htcondor.org stable channel  and it worked fine for me. 
    Here is what I did:
    
    $ docker run -it --rm almalinux/9-base bash
      [root@f5b1fcb6c6ce /]# curl -fsSL https://get.htcondor.org |
      /bin/bash -s -- --no-dry-run --channel stable
      [root@f5b1fcb6c6ce /]# condor_version
      $CondorVersion: 23.0.10 2024-05-09 BuildID: 731952 PackageID:
      23.0.10-1 $
      $CondorPlatform: x86_64_AlmaLinux9 $
      [root@f5b1fcb6c6ce /]# python3
      Python 3.9.18 (main, Jan  4 2024, 00:00:00)
      [GCC 11.4.1 20230605 (Red Hat 11.4.1-2)] on linux
      Type "help", "copyright", "credits" or "license" for more

      >>> import socket
      >>> import htcondor
      >>> import classad
      >>> host=socket.gethostname()
      >>> coll = htcondor.Collector()
      >>> scheddAd = coll.locate(htcondor.DaemonTypes.Schedd,
      host)
      >>> schedd = htcondor.Schedd(scheddAd)
      
    Hope the above helps,
    Todd
