当prob中的元素极限小时，prob.sum()会得到0值，发生除0，请考虑

将
next_point = np.random.choice(allow_list, size=1, p=prob)[0]
代码改为
if prob.sum() != 0:
prob = prob / prob.sum() # 概率归一化
next_point = np.random.choice(allow_list, size=1, p=prob)[0]
else:
next_point = np.random.choice(allow_list, size=1)[0]
或者
2.将
prob = prob / prob.sum()
代码改为
prob = prob / prob.sum() + 1e-10
