Scenario Runner does not work

[NikolaiHoffmann]

Hi there,

I'm having trouble with the setup of the Scenario Runner.
I have CARLA 0.9.13 and my Python version is 3.7.17.
I installed CARLA as recommended and it is running so far.
I also have downloaded version 0.9.13 of the Scenario Runner and followed the steps on the Getting Started page.
Whenever I try to install the requirements with the following comand pip3 install --user -r requirements.txt, I get the error message:

ERROR: Ignored the following yanked versions: 3.4.11.39
ERROR: Could not find a version that satisfies the requirement opencv-python==4.2.0.32 (from versions: 3.4.0.14, 3.4.10.37, 3.4.11.41, 3.4.11.43, 3.4.11.45, 3.4.13.47, 3.4.15.55, 3.4.16.57, 3.4.16.59, 3.4.17.61, 3.4.17.63, 3.4.18.65, 4.3.0.38, 4.4.0.40, 4.4.0.42, 4.4.0.44, 4.4.0.46, 4.5.1.48, 4.5.3.56, 4.5.4.58, 4.5.4.60, 4.5.5.62, 4.5.5.64, 4.6.0.66, 4.7.0.68, 4.7.0.72, 4.8.0.74, 4.8.0.76, 4.8.1.78, 4.9.0.80)
ERROR: No matching distribution found for opencv-python==4.2.0.32

When I ignore that error and try to run the example scenario using python scenario_runner.py --scenario FollowLeadingVehicle_1 --reloadWorld, I get the following error:

Traceback (most recent call last):
  File "scenario_runner.py", line 35, in <module>
    from srunner.scenarioconfigs.openscenario_configuration import OpenScenarioConfiguration
  File "/home/nik/scenario_runner-0.9.13/srunner/scenarioconfigs/openscenario_configuration.py", line 16, in <module>
    import xmlschema
ModuleNotFoundError: No module named 'xmlschema'

I am not even sure if these errors are even related, but I would assume they are.
I have spent so much time trying to solve it, installing suggested stuff manually and reinstalling CARLA and the Scenario Runner, but nothing helped.
Would really appreciate it, if somebody could help me.
Many thanks in advance!
