This happens very frequently, especially with the EnergyObserver.

I'm not able to replicate this, it works for me.

Also, this error message

Could not start EnergyQualityObserver

Comes from the rosgraph_monitor/scripts/monitor#L60 I'll take a look at it, and maybe @ipa-hsd can help us find out why the exception is raised

I'm not able to replicate this, it works for me.

Maybe it is a race condition / timing issue, and in my slow computer it happens sometime. I will move it to wont fix now for the moment.

I pulled the latest observers branch and unable to replicate this. I am able to load and unload the observer.

I think there is some race condition that happens for my slow machine. I leave it open but with wontfix

Thanks @ipa-hsd !! 🎉
