[TVM Discuss] [Questions] Traversing Relay Graph order (source to sink, sink to source)


@comaniac - are you assuming that user needs to extend from the ExprMutator class? 

I have been mostly user of TVM, and now, I'd like to spend some time to understand relay. 

How does this method differs from the post_order_visit function provided by TVM? 
 
[quote="comaniac, post:3, topic:6720"]
```
def visit(self, node):
   super().visit(node)
   // do something
```

Preorder. In this case the first node that processes “do something” would be the last node in a DAG.

```
def visit(self, node):
   // do something
   super().visit(node)
```
