dependency packages error?

[SurferZergy]

Hi, I was running through you example QAOA.ipynb, and ran into error:
module 'pyquil.api' has no attribute 'QVMConnection'
so I downgraded pyquil to 2.1.1 as you mentioned. And then got the stack trace below.
Was wondering if there is a specific python version and forest SDK version i need to run?
(I also had issues getting forest to install, so i just ran the docker (https://docs.rigetti.com/qcs/getting-started/forest-docker-image))
using this command: docker run --rm -it rigetti/forest
