Trying to get demo running

[jake3991]

Hello!

This is some pretty amazing work, I'm hoping to use it as a basis for some robotics research I'm doing myself. I am however, having some issues getting the demo to run take a look at my error trace below. I followed your instructions as per the repo and installed your other repo, arrangement. Looks like there is an skimage warning and then an actual error to do with networkx, any ideas?

Hi @jake3991 , Thank you for your interest in this work and raising the issue.

Please accept my apologies for a very late response, I have been very overwhelmed recently and can't find the time to investigate this issue. I will try to find some time this weekend and fix the issue.

Sorry again for the tardiness.

I will have to try it myself, but I have a hunch it has something to do with the changed interface of the networkx from version 1 to 2. Have you tried enforcing the old version of the networkx in the requirement.txt?

PS: networkx >= 1.10 -> networkx == 1.10

Hello again @jake3991

There has been another issue rising in the other repo (arrangement, which this repo depends on).

As I guessed, that one (and most probably this one) is due to changed API of networkx. The short term solution is forcing the pip to install older networkx.

Short term solution, unfortunately not sure when, will require adaptation of the code to the networkx version bump.
