Pytorch, Pandas, Numpy different result on Windows and Linux
We are working on an AI project which amongst others calculates the position of a human body lying in a bed. External supporters provided us a code package which does this job and calculates the deviation between the real position of the body (detected by a camera) and the predicted position.
That code package has been developed on Windows and now needs to be ported to Ubuntu 20.04. Until now, in the code package for Ubuntu, we just changed some path names (backslash to slash) to make it work.
If we now run – the exactly same - code with the exactly same training and test data under Windows 10 and Ubuntu we observe the following strange behaviour:
The deviation between real body positions and predicted body positions is 25mm (average value) in Windows, which is a good result for our purposes and excepted as a match. In Ubuntu the deviation is 150mm (average value), which is a not usable result.
We also ran the Windows code package in a Windows 10 VM (Virtualbox) on the respective Ubuntu machine. The result is close to the result we get when running the code under ‘plain‘ Ubuntu (not usable).
When running under Ubuntu, there is no difference whether we utilize CPU or GPU.
The code is written in Python 3 and executed under Python 3.7.12 in an Anaconda 3 virtual environment.
We assume that Linux/Ubuntu does not fully support a certain CPU instruction set. but at the end we do not have an explanation for this behaviour. Does anybody have an idea?
