After installing IMX519 drivers I get "ModuleNotFoundError: No module named 'picamera2'" and 'old' camera not recognized

Raspberry Pi Cameras
1

I built a Bullseye 64bit system in a 64GB card some days ago. Using it in a Pi3B+
I tried successfully libcamera-still with a OV5647 and also running a python script with picamera2 module that is already installed from scratch.
Always working from ssh.

To test a new 16MB IMX519 Arducam camera I followed your pdf instructions and installed all stuff needed.

The camera worked perfectly using the command libcamera-still (I didn’t try python script)

Then I replaced this camera by the OV5647.

Running my python script I successfully used before installing those drivers I get

from picamera2 import Picamera2
ModuleNotFoundError: No module named ‘picamera2’

Trying to take a picture from command line the command libcamera-still outputs:

Preview window unavailable.
[0:00:58.588281330] [1509] INFO Camera camera_manager.cpp:293 libcamera v0.0.0+3897-c3c878a9.
ERROR: *** no cameras available ***.

The camera is connected as usual (also tried changing the connection strip)
System updates were also performed.

So there are 2 issues: No ‘old’ camera recognition and no more module picamera2.
That said I can use only the 16MP camera from command line.
Thank you

Hi,
Can you post the content in the /boot/config.txt?

cat /boot/config.txt

3 
dtparam=audio=on
camera_auto_detect=1
display_auto_detect=1
dtoverlay=vc4-kms-v3d
max_framebuffers=2
arm_64bit=1
disable_overscan=1
otg_mode=1
arm_boost=1
gpu_mem=128
dtoverlay=imx519

I’ve read in picamera2 doc that gpu_mem is better not to be set. I was testing other stuff and forgot to comment that line.
Thanks

Any help please? I’m stuck here and I don’t want to mess up changes.

Hi,
Could you post the whole content of config.txt file?
I think you forget to comment the dtoverlat for cameras you used before. :blush:

You can change camera_auto_detect=1 to camera_auto_detect=0
Then reboot your Pi to take effect.

With a OV5647 camera and running a python script.

from picamera2 import Picamera2
ModuleNotFoundError: No module named ‘picamera2’

It seems that you have not installed the picamera2 relevant dependencies.
Please follow the link below to install it:
https://docs.arducam.com/Raspberry-Pi-Camera/Native-camera/PiCamera2-User-Guide/

It is my bad. I should have told you that you need to comment dtoverlay=imx519
and add dtoverlay=ov5647 under [all]. Then you need to reboot your device to take effect.

Hi Dion,

As for picamera2 dependencies I executed

sudo apt install -y python3-kms++
sudo apt install -y python3-pyqt5 python3-prctl libatlas-base-dev ffmpeg python3-pip
sudo pip3 install numpy --upgrade
sudo pip3 install picamera2 --upgrade

Reboot

Then I ran a python script with the module picamera2 and the OV5647 camera and got

During handling of the above exception, another exception occurred:

Legacy camera is already disabled.
Camera connection is okay (replacing Bullseye sd card by a Buster one camera is okay)
Thank you

PS: I get the same errors with 16MP camera attached
