The version of stochastic_optimization.ipynb available in course colabs has stopped installing for me, failing with the error:

Could this be resolved?

looks like it reproduces for other notebooks too
(have tried policy_gradient.ipynb)

RussTedrake commented

This is due to google colab updating (without warning) from python3.6 to python3.7
I have updated the installation script in intro.ipynb and the early chapters (if you grab the first cell from that notebook, then these notebooks should work, too). I'll update the rest very soon!

oops. it's the intro.ipynb from my underactuated notes that I've updated. i'll fix this one now, too.

RussTedrake commented

These notebooks (and most notebooks) should work again now, albeit with a few warnings on installation that will take some more cleanup. Do let me know if you find any other problems.
