Hi again,
Just to say that I have installed the nightly version of julia
(0.4.0-dev+5920 (2015-07-10) and checked out the master branch of PyCall,
by running:
Pkg.rm("PyCall")
Pkg.add("PyCall")
Pkg.checkout("PyCall")
Now my python-igraph library seems to be working perfectly. I could
successfully run this toy example:
```
julia> using PyCall
julia> @pyimport igraph
julia> gg = igraph.Graph()
julia> g = gg[:Barabasi](5)
julia> g[:degree]()
5-element Array{Any,1}:
3
1
1
2
1
```
I will start working with python-igraph, but I will also take a look at
Cxx.jl to see if I can use it as an alternative. Thanks a lot for your help
and your advice!
Best,
Charles
