When installing SlicerRT it says

except Exception, e:

Thanks for the report! We are in transition to Python3, which is not a trivial task, so it might take a while until everything is functional again.

I’ll fix this asap though. And please keep reporting anything new that comes up!

@Alex_Vergara SlicerRT works in the latest nightly. There is one more error coming from Slicer core when you load an RTImage, but otherwise it seems to works well. I’ll still do some tests to make sure, but I think the main functions should be fine now. Thanks for the report!
