Thank you very much for the helpful instructions. It worked on my raspberry pi with buster. Do you have any idea about this: "UserWarning: NumPy 1.16.5 or above is required for this version of SciPy (detected version 1.16.2)"? I unistalled the one that was installed and I installed a new one with "apt install python3-numpy" but I get this warning
