Problem in running the a3c folder files

[SExpert12]

Hi,
I run the file named "python3 continuous_A3C_base.py"
and it shows nothing.

Then I run the file "python3 continuous_A3C_tune.py"
I got this error.
"Gymnasium minimally supports python 3.6 as the python foundation not longer supports the version, please update your version to 3.7+"
Traceback (most recent call last):
File "continuous_A3C_tune.py", line 13, in
from rllib.models import register_carla_model
File "/home/ryzen/macad-agents/src/macad_agents/rllib/models.py", line 12, in
from ray.rllib.models.model import Model
ModuleNotFoundError: No module named 'ray.rllib.models.model'
Killing live carla processes set()

There is no Model exists.
So how to change this?

Then I run the file "python3 continuous_A3C.py"
I got this error.

"Gymnasium minimally supports python 3.6 as the python foundation not longer supports the version, please update your version to 3.7+"
Traceback (most recent call last):

self._fixed_delta_seconds = self._env_config["fixed_delta_seconds"]
KeyError: 'fixed_delta_seconds'
Killing live carla processes set()

How to solve this errors?
What is the output of file named ""python3 continuous_A3C_base.py" because it shows nothing.

thanks
