Raspberry Pi Forums

I developed a program on a Raspberry Pi 3 board using Python 3, PYQT5. I also used rip.gpio and smbus to talk to the hardware with the 7" LCD touch screen. Now I'm trying to fit the application in the memory of the Compute Module with Jessie Lite. I'm not sure what additional modules I need to install. Does anybody have any ideas?

I tried going the other way and using my working install and removing things I don't think I need until I get to the point where it doesn't work any more, but this is a long and tedious process.

Start with Raspbian Jessie Lite then install the GUI on top of that. You'll save masses of eMMC space that way.

sudo apt-get install -y raspberrypi-ui-mods gets the GUI installed on top of Jessie Lite.
