Not able to run discrete or continous file

[SExpert12]

Hi,
When I run the continous file I got this error:

##################################################################################################
python continuous_driver.py --exp-name ppo --town Town07
##################################################################################################
Couldn't import Carla egg properly
pygame 2.1.2 (SDL 2.0.16, Python 3.8.10)
Hello from the pygame community. https://www.pygame.org/contribute.html
ERROR:root:Connection has been refused by the server.

Exit

env = CarlaEnvironment(client, world,town)
UnboundLocalError: local variable 'client' referenced before assignment

As I am getting error related to egg file. I also add these lines in the continous flie:
try:
import pygame
except ImportError:
raise RuntimeError('cannot import pygame, make sure pygame package is installed')

try:
import numpy as np
except ImportError:
raise RuntimeError('cannot import numpy, make sure numpy package is installed')
except ImportError:
raise RuntimeError('cannot import pygame, make sure pygame package is installed')

Calra module

try:
sys.path.append(glob.glob('../carla/dist/carla-*%d.%d-%s.egg' % (
sys.version_info.major,
sys.version_info.minor,
'win-amd64' if os.name == 'nt' else 'linux-x86_64'))[0])
except IndexError:
pass

But still I am getting the error related to the egg flie. My other files are working perfectly in CARLA.

When I run the file for discrete file. I got this error.

python3 discrete_driver.py
Couldn't import Carla egg properly
pygame 2.1.2 (SDL 2.0.16, Python 3.8.10)
Hello from the pygame community. https://www.pygame.org/contribute.html
Traceback (most recent call last):
File "discrete_driver.py", line 16, in

ImportError: cannot import name 'TOWN7' from 'parameters' (/home/ryzen/Autonomous-Driving-in-Carla-using-Deep-Reinforcement-Learning-main/parameters.py)

So I add this line in parameters.py file
TOWN7 = "Town07"

And then I got this error:

python3 discrete_driver.py
Couldn't import Carla egg properly
pygame 2.1.2 (SDL 2.0.16, Python 3.8.10)

How to resolve both these errors?
