AttributeError: 模块“networkx”没有属性“Graph”

Question

I installed networkx by downloading the distribution file and running:

python setup.py install

It appears to have been successful, I got this message after installing

Installed c:\python\python36-32\lib\site-packages\decorator-4.0.11-py3.6.egg
Finished processing dependencies for networkx==1.11

But when I run a really simple test code, I get errors

import networkx as nx

G=nx.Graph()

print(G.nodes())
print(G.edges())

print(type(G.nodes()))
print(type(G.edges()))

> Traceback (most recent call last):   File "netExample.py", line 3, in
> <module>
>     G=nx.Graph() 

> AttributeError: module 'networkx' has no attribute 'Graph'

Running print(dr(nx)) gives the following attributes:

Answer 1

Following the below steps, it worked for me in python 3.5 version.

1. Downloaded networkx-1.11.zip
2. Extracted the zip file
3. open the cmd and cd to extracted directory
4. run python setup.py install
5. verified the installation using pip freeze
6. saved the test code in netExample.py file.
7. In CMD, cd to the folder, which contains netExample.py
8. run python netExample.py

Following is output that I got:

D:\Naveen\so>python netExample.py
[]
[]
<class 'list'>
<class 'list'>

Please check the following:

1. Verify whether you are downloading from the official website.
2. Check if any other file named networkx.py is present in Windows Path before the actual networkx module is present in
