Description

When I executed /examples/src/main/python/pagerank.py 

The result is shown as follows

 

1 has rank: 0.5821576292853757.

2 has rank: 0.3361551945789305.

3 has rank: 0.3361551945789305.

4 has rank: 0.3361551945789305.

 

However, the same graph executed in networkx-pagerank. The result 

shown as follows

{1: 0.4797305739863632, 2: 0.1734231420045456, 3: 0.1734231420045456, 4: 0.1734231420045456}
