>             Project: Singa
>          Issue Type: New Feature

> This type of convolution is used in [Xception 
> model|https://arxiv.org/pdf/1610.02357.pdf] and is supported by [other 
> libraries|[https://github.com/pytorch/pytorch/issues/1708].]
>  
> To implement it in Singa, we create a new operation (separable_conv_2d) by 
> calling a depthwise_conv_2d (normal convolution with number of output 
> channels=1, and number of groups = number of input channels); and then 
> calling normal convolution with number of groups=1, and kernel size=1, i.e. 
> pointwise convolution.
