源码教程 sum along column of matrix: paddle.sum api 无法使用

自己的环境下还是在aistudio下都无法使用。     1）PaddlePaddle版本：1.7    2）CPU/GPU：cpu/gpu都不行    3）系统环境：Mac OS 10.14    4）Python： 3.7

Traceback (most recent call last): File "train_vae_linear.py", line 124, in train(model) File "train_vae_linear.py", line 63, in train loss = loss_function(recon_batch, img, mu, logvar) File "train_vae_linear.py", line 26, in loss_function BCE = paddle.sum(BCE, dim=1) AttributeError: module 'paddle' has no attribute 'sum'

doc中没有相关例子 然而在源码里面有个教程： 但是一下例子无法使用 ''' Examples: .. code-block:: python

        import paddle
        import paddle.fluid as fluid
        # x is a Tensor variable with following elements:
        #    [[0.2, 0.3, 0.5, 0.9]
        #     [0.1, 0.2, 0.6, 0.7]]
        # Each example is followed by the corresponding output tensor.
        x = fluid.data(name='x', shape=[2, 4], dtype='float32')
        out1 = paddle.sum(x)  # [3.5]
        out2 = paddle.sum(x, dim=0)  # [0.3, 0.5, 1.1, 1.6]
        out3 = paddle.sum(x, dim=-1)  # [1.9, 1.6]
        out4 = paddle.sum(x, dim=1, keep_dim=True)  # [[1.9], [1.6]]

        # y is a Tensor variable with shape [2, 2, 2] and elements as below:
        #      [[[1, 2], [3, 4]],
        #      [[5, 6], [7, 8]]]
        # Each example is followed by the corresponding output tensor.
        y = fluid.data(name='y', shape=[2, 2, 2], dtype='float32')
        out5 = paddle.sum(y, dim=[1, 2]) # [10, 26]
        out6 = paddle.sum(y, dim=[0, 1]) # [16, 20]
