super(_open_file, self).init(open(name, mode)) PermissionError: [Errno 13] Permission denied: 'model/topo_based'

This error occurs when the program is trying to open a file or directory with insufficient permissions. The file or directory in question, 'model/topo_based', may not have read, write, or execute permissions for the user running the program.

To fix this error, ensure that the program has the necessary permissions to access the file or directory. You can check the permissions using the 'ls -l' command in the terminal. If the permissions are insufficient, you can change them using the 'chmod' command.

For example, to give the program read and write permissions for the 'model/topo_based' directory, you can run the following command:

chmod +rw model/topo_based

Note that you should only give permissions to the program that needs them, and not to everyone. Use the 'chown' command to change the owner of the file or directory if necessary.
