Chapter 7 Example 5 doesn't compile

[ghost]

The example 5 about constructing an ego graph of a repository and its stargazers doesn't work. I don't know how to fix it.

Oops, didn't see that I have to fill in access key. Did that, I don't see any output when I evaluate the cell with a Shift + Enter. What am I missing here? Thanks!

Which example? And which GitHub account/repo are you running against so I can be sure I am experiencing the same issue? I'll try to take a look and provide some help later today.

@ptwobrussell Chapter 7 Example 5 about constructing an ego graph of a repository and its stargazers. I put in my access key and left the default username (yours) and repo (this repo).

Example 7-5 constructs the graph. You have to then run Example 7-6 to display some stats about it. Are you also running example 7-6? If so, you are getting some kind of output. Can you share it?

I am not able to see any graph output from 7-5. Running example 7-6 though I receive a long output, first few lines here...

Name: 
Type: DiGraph
Number of nodes: 961
Number of edges: 960
Average in degree:   0.9990
Average out degree:   0.9990

{'lang': u'JavaScript', 'owner': u'ptwobrussell', 'type': 'repo'}
{'type': 'user'}

{'type': 'gazes'}

{u'Mining-the-Social-Web(repo)': {'type': 'gazes'}}
{}

[]
[('ptwobrussell(user)', u'Mining-the-Social-Web(repo)')]

[ptwobrussell]

Slight both examples are working as expected then. Did you have any additional questions?

What do you mean by "slight"? I am new to this and my question is, should example 7-5 be generating a graph? (a picture of a graph, something visual I mean)

[ptwobrussell]

Sorry, typo. Slight -> "sounds like"

Example 7-5 just constructs a data structure called a graph (which can later be rendered visually with a layout algorithm and visualization toolkit). Later examples display it's properties an manipulate it.

Are you following along with the book? Would be very helpful context if you are new to this.

Oh I see, thank you that makes sense. I haven't followed the book from the start but will do so, thank you. Closing this issue.

[ptwobrussell]

Sounds good. This particular chapter is written as an almost standalone primer on graph analysis, so if you follow along carefully, I think it will be very helpful to you.

If anything else comes up, please don't hesitate to reach back out
