这是重现我的问题的示例：
a = np.array([[1,2], [3,4], [6,7]])
b = np.array([[1,2], [3,4], [6,7,8]])
c = np.array([[1,2], [3,4], [6]])
print(a.flatten())
print(b.flatten())
print(c.flatten())
当其中一个数组的项目少或多时，就会出现问题。
Output:
[1 2 3 4 6 7]
[list([1, 2]) list([3, 4]) list([6, 7, 8])] # Won't work
[list([1, 2]) list([3, 4]) list([6])] # Also won't work
How I want it:
[1 2 3 4 6 7]
[1 2 3 4 6 7 8]
[1 2 3 4 6]
有谁知道如何正确展平列表，例如 b 和 c？
