Error at main.py

Traceback (most recent call last): File "\DQN-Flappy-Bird-master\DQN-Flappy-Bird-master\src\main.py", line 66, in main() File "\DQN-Flappy-Bird-master\DQN-Flappy-Bird-master\src\main.py", line 61, in main trainer.train() File "\DQN-Flappy-Bird-master\DQN-Flappy-Bird-master\src\train.py", line 113, in train agent.save(episode, logs_path) File "\DQN-Flappy-Bird-master\DQN-Flappy-Bird-master\src\agent.py", line 134, in save min_step = min([int(li.split('/')[-1][6:-4]) for li in model_list]) File "\DQN-Flappy-Bird-master\DQN-Flappy-Bird-master\src\agent.py", line 134, in min_step = min([int(li.split('/')[-1][6:-4]) for li in model_list]) ValueError: invalid literal for int() with base 10: 'odel-1000'

This is the error I got when I ran main.py
