LineGraph not working

[HDubois-fr]

Hi,
I'm using pygsp v0.5.1 installed through conda, and when running the LineGraph example

graph = graphs.Sensor(5)
line_graph = graphs.LineGraph(graph)

I get the following error:

AttributeError: module 'pygsp.graphs' has no attribute 'LineGraph'

Also, if i add the k=2 parameter to the graph = graphs.Sensor(5), i get the following:

TypeError: __init__() got an unexpected keyword argument 'k'

That's because you are using the stable version of the PyGSP (installed by conda and pip) while you are looking at the development version of the documentation (corresponding to the github master branch). You can either install the development version with pip install git+https://github.com/epfl-lts2/pygsp or look at the stable documentation at https://pygsp.readthedocs.io.
