可以多加两个例子
- 只输入 1 个 tensor
- shape 中有 0 的情况；

这里是测试case中静态图的时候发现如果输入的 x 中有 zero-size tensor，静态图最终会返回 None，然后排查了一下应该是 reshape op 在静态图下输入是 zero-size tensor 的话会返回 None。（如果输入的 x 中有 zero-size tensor，静态图下 coordinates = paddle.stack(paddle.meshgrid(x), axis=-1) 这一步有返回结果，且coordinates也会是 zero-size tensor，最后一步 reshape 返回了 None）
如果注释掉 kernel 这里的直接 return，静态图就返回的是 []，动态图没有影响，不知道这样改对不对。
