When I run python car_example.py, I get the traceback below. I understand that the issue may raise from different SciPy version. Any Idea how to solve it? An addition of the requirements.txt for stating which version of Scipy to use this with would be good, if a solution is not available. According to LAPACK documentation, the third argument is for precision so I first thought it was a SciPy bug but the function works as intended when used separately.
