构造data_layer的代码如下：

X = paddle.layer.data(name="X", type=paddle.data_type.dense_vector_sequence(12))

生成数据的代码如下：

data = np.array([[0.] * 12] * 46)
yield data

然而实际执行的时候报错：Check failed: height_ == label.getSize() && width_ == 1 && height_ == output.height_ Matrix dimensions are not equal 堆栈信息上看似乎是bp的时候出错的。 堆栈信息如下：

* Check failure stack trace: *

麻烦大神帮忙看一下，谢谢。
