I am running a pyenv with 3.10.5 for a RPi 4 b. RPi OS version if important:
pi@raspberrypi:~ $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
...
The pyenv was simply the solution I could find for running python3.10 with a bit of ease on RPi.
I have a personal script camera_profiles.py that depends on Picamera2, and when I call it:
File "/home/pi/MYPATH/camera_profiles.py", line 8, in <module>
from picamera2 import Picamera2
File "/home/pi/.pyenv/versions/3.10.5/lib/python3.10/site-packages/picamera2/__init__.py", line 1, in <module>
from .picamera2 import Picamera2, Preview
File "/home/pi/.pyenv/versions/3.10.5/lib/python3.10/site-packages/picamera2/picamera2.py", line 10, in <module>
import libcamera
ModuleNotFoundError: No module named 'libcamera'
So I need libcamera as a dependency for picamera2, however pip install libcamera finds nothing.
The following link shows how to build libcamera, but I am unsure how this relates to usage as a module within pyenv. I'm also fairly certain my libcamera is preinstalled and works because of the following command working:
pi@raspberrypi:~ $ libcamera-hello -t 1 --nopreview

.. So I don't imagine installing from source will help me with this issue, but then how do I actually give picamera2 its libcamera dependency?
pip installmost packages while in pyenv3.10.5 it takes a long time to complete, perhaps that's because the prebuilts do not exist for 3.10.5 and it instead fetches the source, and then builds? I also had to build Scipy and seemingly Pillows from source. I don't think building libcamera automatically makes a wrapper module for python, though, looking a the few resources there are about the topic on the net.
