Issue with VecFrameStack

[hibergman]

Hi Nick,

Excellent project and video!

I'm just getting stuck with the hyperparameter tuning section (Approx 2 hours into tutorial)

I'm getting an issue with VecFrameStack when I try to run the study.optimise function
(AssertionError: VecFrameStack only works with gym.spaces.Box and gym.spaces.Dict observation spaces)

As far as I can tell, the observation space IS in a gym.spaces Box

Any idea what is going on here or how to remedy? - Would love to get to the end of the tutorial!

Many thanks,

Henry

Did you ever figure this out?
I am running through the tutorial and am having this issue.
