• Due to the pixel-wise filling and drawing, segmentation models are relatively slow

Tips.

• If you need extra space delete the opencv and the opencv_contrib folder from the SD card. They are no longer needed since all libraries are stored in the /usr/ directory.
• Use a tool like GParted sudo apt-get install gparted to expand the image to larger SD cards. We recommend a minimum of 64 GB. Deep learning requires a lot of space.

Thanks.

A more than special thanks to Stuart Naylor, who, ever so kindly, provided us with the Rock Pi 5 for free.
And Joshua Riek for all the hard work on the Ubuntu OS.
