networkx ImportError: cannot import name _distributor_init

Question

I was trying to use networkx library in my program. It ran well with no complaints at all. But now it suddently starts to complain though I didn't make any change to the program. Very weird. I have tried to reinstall networkx and numpy, but the system just says they are satisfied.

Traceback (most recent call last):
  File "degree_discount.py", line 4, in <module>
    import networkx as nx 
  File "/home/jessy/venv/local/lib/python2.7/site-packages/networkx/__init__.py", line 98, in <module>

    from . import _distributor_init
ImportError: cannot import name _distributor_init

Answer 1

I figured this out. I created a python file called 'random.py'. And I had "import random" in my degree_discount.py, so I guess python was confused.
