I have encountered an issue with installing the pi-top SDK on Raspberry Pi OS. well it installs perfectly fine but the pt-sys-oled service has an issue starting.

Looking at the daemon.log it shows this

Jun  4 19:46:57 pitopIOT pt-sys-oled[16807]: Traceback (most recent call last):

Any ideas on how to fix it?

Ok i figured out the issue. @duwudi @pi-topMIKE you may want to add the following to the SDK dependencies, as after running that command it worked perfectly

sudo python3.7 -m pip install opencv-python

just for a note, i installed the SDK from the info here

I have captured this bug here: https://github.com/pi-top/pi-top-Python-SDK/issues/363

i installed the SDK on a headless install and found that i had to install more than just openCV

sudo python3 -m pip install opencv-python
sudo apt install -y libopenjp2-7 libilmbase-dev libopenexr-dev libgstreamer1.0-dev libavcodec-dev libavformat-dev libswscale-dev

i added this info to the GitHub issue

The right solution here I think is sudo apt install -y python3-opencv, which should handle the other dependencies that it needs for you.

I did install opencv before installing the SDK and had to install these too

#7

Right, but you installed a different version of OpenCV by virtue of pip installing it. I don’t think that these extra packages are necessary unless you’re specifically intending to use that version of OpenCV.

#8

looks like that’s what it was
