On haros framework, the following works :

haros analyse

And I can visualize the results, but it doesn't with the -n option for the graphs. So 

haros analyse -n

spits the following error, related to bonsai-code :

AttributeError: 'float' object has no attribute 'walk_preorder'

I ran the latest haros branch on a ROS2 workspace. Is there a way to fix this ? It would be very helpful to see the generated node-graph models for ROS2. Great features :crossed_fingers:

Hello!

It's likely that you will run into errors on ROS2 code. This was built for ROS1, and there are a few things that will just break.

I am developing a new version of HAROS for ROS2 from scratch, though, but it might be a little while longer until it is ready for the public.
