How to ask for help

I am trying to run the workbooks from …fastai/fastbook/clean on a server at Datacrunch.io using the fastai environment.
The Python code always returns errors of various elements not found; her is an example from the first entry:

---- Start of example -----
fastai 2.3.0 requires fastcore<1.4,>=1.3.8, but you’ll have fastcore 1.0.13 which is incompatible.

Has anybody tried that before?
