I didn't know it was a 'general programing question', I thought it was unique to depthai. I had never seen it before and it was in the API a bunch of times. Sorry, I am struggling a bit trying to figure out how to program in python, how to deal with environments, how to get SBCs running depthai, how to manage cameras and sensors, how to annotate and setup datasets, how to train models, and how to run inference -- with starting from zero and having to one to help me. I have managed so far to get a model trained from my own data with depthai running on a rasbpi zero doing inference properly and getting good detections and not I am stuck on figuring out pipelines. I apologize if I wasted you time with a 'general' questions but at this point I still don't know what I don't know.
