Python 3 Module install folder

Hi everyone

I install python’s module on my Jetson by pip command and I saw 2 folder where module installed:
folder 1: /home/jetson/.local/lib/python3.6/site-packages
folder 2: /usr/local/lib/python3.6/dist-packages
Some module installed into folder 1 and some module installed into folder 2
With the app which has import module installed from folder 2 I can make run at boot by service file in systemd but if the module import from folder 1, when I make run at boot, it has error no module name… (although I can run normally when call from terminal by command: python3
Any body know why exist 2 folder where python’s module installed and how to make app run at boot when module installed to folder 1?
