Application quit abnormally! ImportError: Unable to import required dependencies: numpy

[Jean-Sebastien Provost]

Dear Experts,

I was able to build my app successfully through Xcode, but unfortunately, it crashed immediately reporting the error (see below).

Interestingly, I'm supposedly running a virtual environment with Python 3.7.3 with numpy 1.19. I'm not sure why the log is mentioning Python 3.8. In a previous step, I did build python3 using the following command:

> sudo toolchain build python3 openssl kivy

Is that why it fails to display the app via the Simulator? Any ideas on how to solve this issue?

Thanks,
