It runs fine in python3.6, but runs in python3.12 with the following error:

The reason is that the string conversion mechanism of the enum has been adjusted

The proposed modifications are as follows:

diff --git a/resources/__init__.py b/resources/__init__.py
index 336c41c..ff0ba9e 100644

I hope the author can incorporate it and update it.
