[英]Observation with different boundaries. The observation returned by the `reset()` method does not match the given observation space
我是强化学习的初学者,所以不要苛刻地评判我。
error: AssertionError: reset()
方法返回的观察与给定的观察空间不匹配
观察空间:
self.observation_space = gym.spaces.Tuple((
gym.spaces.Box(low=-float('inf'), high=self.fp.HEIGHT, shape=(1,), dtype=np.float64), # player y
gym.spaces.Box(low=0, high=self.fp.WIDTH + self.fp.MIN_PIPE_GAP + self.fp.PIPE_WIDTH, shape=(2,), dtype=np.float64), # pipes x
gym.spaces.Box(low=-float('inf'), high=float('inf'), shape=(1,), dtype=np.float64), # gravity
gym.spaces.Box(low=-(self.fp.HEIGHT / 4 * 3 + self.fp.MIN_PIPE_GAP + 100), high=self.fp.HEIGHT / 4 * 3 + self.fp.MIN_PIPE_GAP + 100, shape=(4,), dtype=np.float64), # pipes y
gym.spaces.Box(low=self.fp.PX, high=self.fp.PX, shape=(1,), dtype=np.float64) # player x
))
返回观察:
return (
np.array([float(self.py)]), # py
np.array([float(self.pipes[ind]['x']), float(self.pipes[ind + 1]['x'])]), # x1 x2
np.array([float(self.gravity)]), # gravity
np.array([float(self.pipes[ind]['y1']), float(self.pipes[ind]['y2']), float(self.pipes[ind + 1]['y1']), float(self.pipes[ind + 1]['y2'])]), # y1 y2 y3 y4
np.array([float(self.PX)]) # px
)
我试图将所有内容都放在一个数组中(它起作用了),但这是错误的,因为不同的数据组需要不同的边界。 最有可能的是,错误的格式不对,如果根据您的说法,一切都是正确的,那么我会尝试在边框中找到错误
结果证明错误在边界内。 但最后,checker建议使用Dict,所以我就这样重写了代码:
观察空间:
self.observation_space = gym.spaces.Dict({
"player_y": gym.spaces.Box(low=-float('inf'), high=self.fp.HEIGHT, shape=(1,), dtype=np.float64), # player y
"pipes_x": gym.spaces.Box(low=0, high=self.fp.WIDTH * 3, shape=(2,), dtype=np.float64), # pipes x
"gravity": gym.spaces.Box(low=-float('inf'), high=float('inf'), shape=(1,), dtype=np.float64), # gravity
"pipes_y": gym.spaces.Box(low=-(self.fp.HEIGHT / 4 * 3 + self.fp.MIN_PIPE_GAP + 100), high=self.fp.HEIGHT / 4 * 3 + self.fp.MIN_PIPE_GAP + 100, shape=(4,), dtype=np.float64), # pipes y
"player_x": gym.spaces.Box(low=self.fp.PX, high=self.fp.PX, shape=(1,), dtype=np.float64) # player x
})
返回:
return {
"player_y": np.array([float(self.py)]), # py
"pipes_x": np.array([float(self.pipes[ind]['x']), float(self.pipes[ind + 1]['x'])]), # x1 x2
"gravity": np.array([float(self.gravity)]), # gravity
"pipes_y": np.array([float(self.pipes[ind]['y1']), float(self.pipes[ind]['y2']), float(self.pipes[ind + 1]['y1']), float(self.pipes[ind + 1]['y2'])]), # y1 y2 y3 y4
"player_x": np.array([float(self.PX)]) # px
}
