The only time I’ve had version issues running python code is that someone prior was referencing a deprecated library API or using an obscure package that shouldn’t see the light of day in a long lived project. If you stick to the tried and true libs and change your function kwargs or method names when getting warnings, then I’ve had pretty rock steady reproducibility using even an un-versioned “python -m pip install -r requirements.txt” experience I could also be a slob or just not working at the bleeding edge of python lib deployment tho so take it with a grain of salt.
