then i followed theinstruction to setup sumo as mentioned in sumo-rl document . set up paths and tried running basic code, showne below and that is whaen I get this error , please help/provide directions. Thanks

import gymnasium as gym
import sumo_rl
env = gym.make('sumo-rl-v0',
                net_file='path_to_your_network.net.xml',
                route_file='path_to_your_routefile.rou.xml',
                out_csv_name='path_to_output.csv',
                use_gui=True,
                num_seconds=100000)
obs, info = env.reset()
done = False
while not done:
    next_obs, reward, terminated, truncated, info = env.step(env.action_space.sample())
    done = terminated or truncated

You have to replace the string "path_to_your_network.net.xml" with a string containing an actual network file. See the examples https://github.com/LucasAlegre/sumo-rl/tree/main/experiments

You have to adjust the path to the network file.
