Error Running Notebooks NetworkXError: random_state_index is incorrect

[kevthehermit]

This applies to several notebooks but using randomnetwork.ipynb as the example

Running the first two cells results in a couple of errors.

Cell contents

traffic = g.generate_random_traffic_network(
    seed=1, n_clients=50, 
    n_servers={
                "SMB": 15,
                "HTTP": 15,
                "RDP": 15,
            },
    alpha=np.array([(1, 1), (0.2, 0.5)], dtype=float),
    beta=np.array([(1000, 10), (10, 100)], dtype=float),
)

I ran into the same issue with several of the examples too and I think I may have found the problem. By default using the init.sh script provided, the version of the decorator package installed is 5.0.6 - This version seeks to fix a number of issues introduced in 5.0.* versions up to 5.0.5 which started breaking things in Networkx (See Networkx Issue #4718) I don't think it has been properly integrated into Networkx and they have pinned decorator at decorator>=4.4,<5 in the default requirements.txt. Something seems to be overwriting it!

The solution is to manually downgrade the decorator version to 4.3.0

Command:

pip install decorator==4.3

Doing this managed to fix the problems and allowed me to run all of the jupyter notebook examples! Hopefully works for you to @kevthehermit.

Thanks, @br0kej confirming that fixed the issue for me. Will leave this open until it gets fixed upstream.

@br0kej @kevthehermit Thank you both for reporting the issue and suggesting the fix. I see there is already a PR with a fix, I'll get it merged soon!

[Mona-byte]

Thanks for the suggestion. I used conda install -c anaconda decorator==4.3
