Hi
I have made a python file to run on a raspberry pi using the latest camera module 3. When i set my code to run i receive a message saying:
from picamera2 import Picamera2
ModuleNotFoundError: No module named ‘picamera2’
I’ve been looking around and the official BalenaCam isnt working either.
Below is my project, any help would be much appreciated.
Thanks
Hi,
Something I noticed is that you’re building a Stretch image.
In the Picamera2 repo, they say “Picamera2 is only supported on Raspberry Pi OS Bullseye (or later) images, both 32 and 64-bit.”
Maybe changing your image to target a newer OS will help?
Also out of curiosity: why are you installing the module with python directly, instead of using pip?
Thanks for your reply!
Iam new to balena. Which OS would be suitable?
What I’ve done is copied the example of helloworld.py from balena to attempt to make it easier.

Hi,
It’s okay to be new at stuff 
In your Dockerfile.template, can you try changing
FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-stretch-run
to
FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-bullseye-run
It might also be an idea to first try the version of Picamera2 that’s included in the apt repos, instead of the GitHub version:
Instead of
# Clone and install picamera2 from GitHub
RUN git clone https://github.com/raspberrypi/picamera2.git /usr/src/picamera2 \
&& cd /usr/src/picamera2 \
&& python3 setup.py install
try
# Install picamera2 from apt
RUN install_packages python3-picamera2
Just tried to upload it and it logged:

Not sure what to do 
@Jake1 Looks like there is a package that is not available! do you see more errors on the logs?
Hi,
Just did a quick search for the packages; turns out qt4 is gone.
Bullseye does package libqt5gui5 and libqt5test5.
Edit: also didn’t find libjasper-dev, and I’m not seeing a replacement for it.
It’s just that on the logs
Just revamped the entire code using AI and it works however the camera preview isn’t it just shows the picture icon. Their is no camera issues in the log which i find a bit confusing!
This is the new code: GitHub - ALD-Models/Vista-V2
Thanks for sharing the code @Jake1
Could you please confirm what Raspberry Pi are you using? Let us try to reproduce and see how we can help you more.
Thanks @TJvV for helping here
Iam using a raspberry pi 4 connected to a pi camera module 3.
Also I’m trying to make it live stream but Iam not sure if this is an appropriate method. I have attached the original code below:
https://github.com/ALD-Models/Rail-Vista-Balena
Thank you
@Jake1 not sure if you tried the balenaCam project before! Actually I don’t have the pi camera module 3 but maybe you can give a try as you can do a live stream from it as well!
I’ve tried that but i get this error:

Hi,
your problem here is that you’re still trying to use Stretch.
That release is old enough that it was removed from the Debian and Raspbian main repositories.
If you REALLY want to use Stretch, you can try fixing the repository list by adding archive.debian.org and/or legacy.raspbian.org.
To do this, edit your Dockerfile.template, and add this right after the FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-stretch-run line:
RUN sed -ri 's_http[s]?://(deb|security)\.debian_https://archive\.debian_g' /etc/apt/sources.list
RUN sed -ri 's_http[s]?://(deb|archive|security)\.raspbian_https://legacy\.raspbian_g' /etc/apt/sources.list
I don’t have a camera either, so I can’t help fully debug it; but this should at least help move things forward a bit .
Thanks, I’ve Just tried to add it to the Balena Cam and it is showing this error:

Hello @Jake1 is there any reason why you need to use balenalib/%%BALENA_MACHINE_NAME%%-debian:stretch-20190612 ?
As @TJvV mentioned did you try to use bullseye instead of stretch?
Hi,
It sounds like your output doesn’t quite match your Dockerfile.template ?
I found two little bugs in my last suggestion.
It seems the old apt doesn’t have https transport enabled; changing the new URLs to http should help.
Also stretch-updates was removed / replaced with stretch/updates; disabling that repo seems to work.
With the new modifications, your Dockerfile.template should look like:
FROM balenalib/%%BALENA_MACHINE_NAME%%-debian:stretch-20190612
# Change apt repositories to archive.debian.org and legacy.raspbian.org; disable stretch-updates
RUN sed -ri 's_http[s]?://(deb|security)\.debian_http://archive\.debian_g' /etc/apt/sources.list

With a little bit of luck, I should have some time later this week to see if I can get a bullseye build.

@TJvV I’ll be looking forward to seeing your results with bullseye!
Hi,
I did some testing, using your repo (Rail-Vista-Balena) as a basis.
I ran into some issues with the Bullseye build (something weird with pip), so I went straight on to Bookworm.
The following seems to get to the point where it gives an IndexOutOfBounds when trying to initialize the camera in the application:
FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-bookworm-run
# Install system packages required for compiling native extensions
RUN install_packages \
build-essential \
libjpeg-dev \
git \
libatlas-base-dev \
python3-dev \
python3-pip
# Upgrade pip, setuptools, and wheel to ensure we have the latest versions
RUN python3 -m pip install --upgrade pip setuptools wheel
RUN install_packages python3-libcamera python3-picamera2
# Now proceed to install Python dependencies from requirements.txt
COPY requirements.txt /usr/src/app/
RUN pip install --no-cache-dir -r /usr/src/app/requirements.txt
# Copy the rest of your application
COPY . /usr/src/app/
# Enable udevd so that plugged dynamic hardware devices show up in our container
ENV UDEV=1
# Set the working directory
WORKDIR /usr/src/app
# Expose the port for streaming
EXPOSE 8000
# CMD to run your Python application
CMD ["python3", "-u", "src/app.py"]
I think it’s probably a good idea to start with this setup and see what does and doesn’t work regarding the camera.
Once that’s up and running, you can see which versions of the other python libraries (aiohttp etc) you need for your application.
I have also modified the Dockerfile.template from balena-cam; in that one I tried to move as much as possible to the Debian system packages; but couldn’t find a substitute for one library (aiohttp_basicauth), so ended up creating a virtual environment for pip to use.

I hope this helps a bit
Thanks for your reply. I’ve just attempted to re-upload the code with your suggestion. Unfortunately it failed but it also mentioned in the logs
