No module named 'timeout_decorator' in drake vibrating_pendulum

Question

I tried to run from underactuated.exercises.pend.test_vibrating_pendulum import TestVibratingPendulum in vibrating_pendulum.ipynb and I got:

ModuleNotFoundError: No module named 'timeout_decorator'

Answer 1

My guess is that you're running the underactuated notebooks on your local machine and did not install the underactuated requirements?

pip3 install -r underactuated/requirements.txt

will install the timeout-decorator package, and any others you're missing.
