python3.7 doesn't seem to be able to find dependencies

[zergaloid]

I am trying to use the python3.7 runtime and it errors out on

ModuleNotFoundError: No module named 'requests'

requests is a dependency of a module I am including in the function.
What could be the cause of this and why does it successfully include the module itself, then fails on it's dependency?

Everything is installed and works fine without fun.
