报错点:D:\anaconda\lib\site-packages\stable_baselines3\common\base_class.py:687
断点调试发现 observation_space were not given。这是什么意思，萌新菜鸟求教。

可参考 #linyiLYi/street-fighter-ai#16

keys = ['high', 'low', 'bounded_above', 'bounded_below']
setattr(env.observation_space, '_shape', (3,84,84))
for k in keys:
    new_attr = getattr(env.observation_space, k).reshape(3,84,84)
    setattr(env.observation_space, k, new_attr)

# Load the trained model
model = MaskablePPO.load(MODEL_PATH,env=env,custom_objects={'observation_space': env.observation_space, 'action_space': env.action_space})

知道怎么改board大小吗，12*12感觉有点小，改成24，就报错了，也是这个ValueError: Error: Unexpected observation shape (72, 72, 3) for Box environment, please use (3, 84, 84) or (n_env, 3, 84, 84) for the observation shape.

如果改了 board 大小，模型输入部分也要改一下，在 snake_game_custom_wrapper 里面
