the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > according to the error information you provide, looks like running hog_gui. Py KeyError appeared. Specifically, when executing the STRATEGIES[name] line, an error occurred where the name key could not be found. The value of name is 'Pick a strategy', which is not a valid policy name.
Therefore, you need to check your GUI code to see if you have correctly set up the various available strategies and their corresponding names in the "Pick a strategy" drop-down box. If not, you need to make sure you set the policy and name correctly before running hog_gui.py. If you have the policy and name set correctly, you need to further examine your code to see if any other errors are causing the problem.
