I’m not sure I could follow your question completely. Regarding imports in Python, I wrote quite a detailed guide, which you can read to see if it allows you to solve the problem.
With the little information I have, I would say you are probably either running the program from the wrong folder, or you don’t have the same folder structure than the book suggests. What you can do, is put all the Python files in the same folder, and update the import statements. So, for example instead of doing:
from ...Controller import SimpleDaq
you can simply do
from simple_daq import SimpleDaq.
I am not sure where the
Controller are coming from in this context…
