ImportError with "scenarios.py"

Question

Thank you for your help in advance!

I had the following error, for example, when running the first cell in pose.ipynb. I have tried reinstalling drake and manipulation on my local machine with the newest version, but I still have the same problem. Can you please help me out with it?

Answer 1

LoadModelDirectivesFromString was added to Drake only in the last few days. You just need to update your installation of Drake.
