Summary: Fix a bug from topology sort of Graph
Key: SINGA-28
URL: https://issues.apache.org/jira/browse/SINGA-28
Project: Singa
Issue Type: Bug
Reporter: wangwei
Assignee: wangwei
The is a bug in the Sort function of graph.cc, which would push one node into
the 'tmp' queue for multiple times if this node has multiple source nodes.
Solution, check for every node if it is already in the queue before pushing it.
When it is not in the queue, then push it. Otherwise do nothing.
