Did you do a "pip install pigpio" first, as instructed?

Yes i have one installed. The car wheels work with the calibration steering left to right and back to forth but for whatever reason when I run the python manage.py command as you saw I got these issues

I think that the problem is that picamera does not work on the Bullseye 64-bit OS and manage.py is trying to use picamera instead of picamera2 for some reason.
There is no need to activate a camera on the BullsEye OS as it is done automatically (picamera2) during the Bullseye OS install unless a legacy camera is in use and is selected in the raspi-config app.

I have a picam v2 working just fine with the Bullseye 64-bit OS running DC 5.0.dev3.

I ran this . it seems the camera is working.
(myenv) sherif@raspberrypi:~/mycar $ vcgencmd get_camera
supported=1 detected=1, libcamera interfaces=0

@sherifayantayo,

As I posted above, manage.py is trying to use picamera and not picamera2 for some reason.

You might have to uninstall DC, disable the legacy camera, reboot and reinstall DC so that python uses picamera2 and not picamera.

Did you install DC using these instructions: Installation for Donkey Car main (>= 5.0) using Raspberry Pi OS Bullseye

If you installed DC correctly you should see this when running manage.py drive:

INFO:picamera2.picamera2:Configuration successful!
INFO:picamera2.picamera2:Camera started
INFO:donkeycar.parts.camera:PiCamera opened...
INFO:donkeycar.parts.camera:...warming camera
INFO:donkeycar.parts.camera:PiCamera ready.
INFO:donkeycar.vehicle:Adding part PiCamera.

@sherifayantayo,

Did you select enable the legacy camera in the raspi-config app before installing DC?

So I didn’t enable legacy camera before i installed donkey car .
since you just recently installed donkey car , did you have issues with the adafruit pca9685 module when you ran donkey calibrate ?

@TCIII,

No, as I am using an RC HAT.

However, I have not had any issues using the RPi with the PCA9685 module.

Suggestion: I think that you need to take this issue to the DC software forum which will give you much more exposure and a faster solution for your problem.

@sherifayantayo - there should be no picamera in your venv's site-packages path, as @TCIII and @zlite already mentioned. We are now using picamera2. For me, picamera2 is already part of the system python install (living in /usr/lib/python3/site-packages). So even installing it with pip in our virtual env, doesn't do anything for me. What does ls /usr/lib/python3/dist-packages/picamera2 return for you? If it doesn't return anything then I recommend you do:

sudo apt-get update
sudo apt-get upgrade

See if this does the picamera2 install in the system python. If not, you can install it manually by

sudo apt install -y python3-picamera2

Remove your current virtual env (just delete it) and re-create it, following the donkey docs. Even if you don't have pycamera2 in your system python, the donkey install would install it there as it is part of the dependencies. Make sure you don't enable the legacy cam in raspi-config. So long story short, picamera2 should be either in your system python or your venv but picamera should not be in any of those. This will likely get the camera to work.

@sherifayantayo I have a hunch that legacy camera was chosen at some point and now you have picamera instead of pycamera2. I suggest you reinstall from scratch, again using the 64bit OS, but make sure NOT to enable legacy camera at any point. After installing the OS just go on with the install as documented and everything should work.
