--------------------------
Assignee: wangwei
> Fix a bug of net.py backward function for layers with multiple inputs
> ---------------------------------------------------------------------
>
> Key: SINGA-283
> URL: https://issues.apache.org/jira/browse/SINGA-283
> Project: Singa
> Issue Type: Bug
> Reporter: wangwei
> Assignee: wangwei
>
> For layers with multiple inputs, their source layers are visited in the
> reversed order, e.g., s1, s2, s3 -> o (forward), => o, s3, s2, s1
> (backward). Consequently, we need to reverse the order of the output
> gradients of o.
> There is a bug of the reverse operation.
> It could be fixed by: reverse(list) --> list[::-1], the first one returns a
> reverselistiterator instead of a list.
