Raspberry Pi Powered live Train station monitor

Product support

Hi I posted a comment on the blog post about the live train station monitor as I’m having issues pushing the file to balena. Chris suggested posting a topic here to work out what is going wrong.

This is the full build log:

Gregor, for this one, I’ll attempt to duplicate this, but as a quick test, in the Dockerfile, try replacing %%BALENA_MACHINE_NAME%% with ‘raspberrypi3’ (without the quotations). I suspect this is an issue with using a 64-bit container.

Hi,

I tried changing this but I got the same error code.

Thanks,
Gregor

Thanks Gregor, we had a look at this, and indeed something about the pip installation process changed, that we were unaware of. We’ve pushed an update that solves the issue, and, if you re-download the application (or delete it and git clone it once again), you should be able to build it successfully now. Thanks for brining it to our attention!

Brilliant, I’ll try it justnow!

That seems to have solved it! Thanks for the help!

Great, thanks for letting us know this broke!

:slight_smile:

This issue still seems to reside. Building for a raspberry pi 4, but using a raspberrypi3 image. I still get:

[jupyter]  Step 4/12 : RUN pip install numpy pandas matplotlib -i https://www.piwheels.org/simple && pip install jupyter jupyterlab

Hi Nathan ,
when you are saying ‘using a raspberrypi3 image’ do you mean you have modified the FROM line in dockerfile.template from %%BALENA_MACHINE_NAME%% to ‘raspberrypi3’ as indicate earlier in this thread ?

15

Yea, I changed it to use balenalib/raspberrypi3-debian-python. Not using any templating.

Hi Nathan, can you please try pulling the latest source code for the project, and try again? There was a fix for it that removes piwheels, which should fix the issue. The error you are seeing doesn’t seem related to the OS image.
