Greetings,
I’m new. I’m a novice, too. Pi5 + picar-x ai cam. I’ve followed the sunfounder tutorials, but have run into serious problems.
So, I’ve already done a new image and reinstall which came back to the same issue. As I’ve gone through the python tutorials, I hit a wall when I run example 7 with the camera. My first install, I actually had my controller app connect and fail to work with the camera. Anyways, I saw this forum thread…
There seems to be typos causing some troubles in the code. I checked my picarx.py file and found the same “_flie” error. Fixing the 3-4 typos in that file didn’t make the core problem go away in itself. I am not sure exactly what the next steps are here.
I need help.
I’m eager to both get the camera working and also see the sunfounder app work properly, so that I can move onto new projects. Any tips?
Here’s the log from running ~/picar-x//example/7.display.py
sudo python3 7.display.py
