 * 4-D with shape [batch, in_height, in_width, in_channels] or [batch, in_channels, in_height, in_width].
 * @li out_backprop: A Tensor. Must have the same type as x. 4-D with shape [batch, out_height, out_width, out_channels]
 * or [batch, out_channels, out_height, out_width]. Gradients with respect to the output of the convolution.
*@par Attributes:
 * Four attributes:
 * @li filter_sizes: A Tensor of type integers. An integer vector representing the tensor shape of filter,
 * where filter is a 4-D tensor [filter_height, filter_width, in_channels, out_channels]
 * or [out_channels, filter_height, filter_width, in_channels] or [out_channels, in_channel, filter_height, filter_width].
 * @li strides: A tuple/list of 2 integers. The stride of the sliding window for H/W dimension.
 * @li pads: A tuple/list of 4 integers, [top, bottom, left, right] pads on feature map
 * @li dilations: A tuple/list of 4 integers, The dilation factor for each dimension of input, now only support [1,1,1,1].
*@par Outputs:
 * y: A Tensor. Has the same type as x
