bug描述 Describe the Bug

shape1 = paddle.randn((2, 8, 32, 34, 3)).unfold(3, 3, 1).shape
print(shape1)
shape2 = paddle.randn((2, 8, 32, 34, 3, 3)).unfold(3, 3, 1).shape
print(shape2)
shape3 = paddle.randn((2, 8, 32, 34, 3)).unfold(3, 3, 1).unfold(3, 3, 1).shape

报错如下：

对比了一下pytorch中的Tensor.unfold，并没有不能连续处理的问题，如下图：
