PR Major change:
Introduce
SubgraphSelectorV2that acceptsBiDirectedNodeinstead ofnnvm::Nodeto get full context of visited node.BiDirectedNodeis double linked version ofnnvm::Node, which can list the output consumer of node. This is very useful to help make selection which has output requirement. Wrapper classSubgraphSelectorV2Bridgeis added to convertSubgraphSelectortoSubgraphSelectorV2, which allows developer to continue using oldSubgraphSelector. So this feature is fully back-compatible.Introduce
kAdjustmode forSubgraphPropertyto allow adjusting network parameters instead of create new node. New APIAdjustSubgraphNode()is added toSubgraphPropertyfor this, which can adjust selected nodes attributes. This is useful when we don't want to create new subgraph node, but to do some modification on selected nodes. Quantized scale alignment optimization is pending on this feature.Change the behavior of PartitionGraph to create single subgraph node for nodes isolating with each other. https://cwiki.apache.org/confluence/display/MXNET/Enable+Operator+Level+Parallelism+under+Subgraph is depending on this change.
Add new subgraph pass "quantized scale alignment optimization" as an example for new subgraph API.
