Let’s try installing from source to see what errors we get that way, run this:
cd ~/
git clone https://github.com/pi-top/pi-top-Python-Common-Library
cd pi-top-Python-Common-Library
pip3 install -e .
cd ~/
git clone https://github.com/pi-top/pi-top-Python-SDK.git
cd pi-top-Python-SDK
pip3 install -e .
I’m not familiar with that OS or if this will work, but it’s worth a shot!
Also, if you get another cython error try running pip3 install cython
Hi Duwudi,
thanks for Your suggestions. I did that (pip3 install cython and then the first pip3 install -e . and the clone of the pi-top-Python-SDK) It worked without errors. When I try the second pip3 install -e . (the one about the pi-top-Python-SDK) I get something I can not post here because as a new user I am only allowed to post 2 links, and the forum finds many of them, so I put the log here:
http://www.l4a.org/compilingerrors.pi-top-SDK.txt
it seems there are several libraries missing for the compilation, but I can’t identfy or find out where to get them.
Cheers&Thanks
Peter
Has anybody a suggestion about another try to compile PythonSDK? See the errors in compilingerrors.pi-top-SDK.txt in the previous post.
Cheers Peter
Hello duwudi,
thanks for the response. I have come quite far now with the following recipe, most of it being Your ideas:
sudo apt install gfortran libv4l-dev liblapack-dev
pip3 install cython
pip3 install scipy
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
python3 -m pip install zmq
cd ~/
git clone https://github.com/pi-top/pi-top-Python-Common-Library
cd pi-top-Python-Common-Library
pip3 install -e .
cd ~/
git clone https://github.com/pi-top/pi-top-Python-SDK.git
cd pi-top-Python-SDK
pip3 install -e .
This ends up with a PythonSDK without any more errors.
When I type “pi-top devices hub”, though, or “pi-top battery” I get the error that there is no response from pt-device-manager. Of course that package is not installed because of the arm64 architecture, which was the beginning of all and the reason trying to install the pi-top PythonSDK from source.
So I am stucked again … do You have any suggestions?
Cheers
Peter
@DEACTIVATED69352686 yeah we don’t have pt-device-manager available to install except via apt and there’s no 64-bit version - this will be supported in the future but it’s not a priority for now. Are you looking to just get the battery readings or something more?
I feel like I could have saved everyone a lot of time by mentioning this earlier 
If this is the only thing blocking you, then perhaps I can attempt to bring forward an experimental 64-bit build of the device manager. No promises, though!
Hello all,
thanks for Your remaks and offers.
I really do need battery check only (and perhaps a shutdown including power off - but that would be purely luxurious).
But if I type “pi-top battery” I am told “Error on pitop-battery.run: Resource temporarily unavailable”. If I type “pi-top devices” I get “Unable to get device type from pt-device-manager: Resource temporarily unavailable”. This happens both as root or unpriviledged user.
As I can’t find any file on the system named pitop-battery.run I do not know what to do.
An experimental package pt-device-manager for arm64 would probably not help, because there are many dependencies - and Devuan uses sysv as an init system and has no systemd (which pt-device-manager uses). But a 64bit pt-device-manager would perhapsly help with Pi OS - I could experiment with that as well because I have it on another sdcard.
Actually the pt-device-manager seems to be a pure Python script - I do not quite understand why the architecture is armhf at all - I would have named it as an “all” package instead of “armhf” - and the several dependencies look the same, as far as I have managed to look after them.
Cheers
Peter
This is happening simply because you do not have the device manager installed.
You’re right that the package currently specifically handles systemd only. However, if you know how to also include support for sysv in the same package, I would be happy to accept that into the source!
For your purposes, you could simply set up the entrypoint to run on boot, and you have successfully replaced the systemd part of the package. Everything else should run, and you should get battery information!
It seems that you are absolutely right about the fact that the architecture of the package could be defined as all! I guess there was some confusion on our end when we were labelling these packages!
We have already adopted this on our SDK (PR here), and I should be able to do something similar to the device manager shortly!
This is a huge improvement for us, so I really appreciate your input!
Here is the latest ‘all’ build of the device manager: https://transfer.sh/Q4ijQ/pt-device-manager_4.1.1-5.gbp0267c7_all.deb
This will likely be going into our apt repository soon, but thought you might want it sooner.
Let me know how you get on 
Hello pi-topMike,
I managed to install the pt-device-manager
with
dpkg --force-depends -i pt-device-manager_4.1.1-5.gbp0267c7_all.deb.
I received the following remarks about missing packages:
pt-device-manager hängt ab von python3-pitopcommon; aber:
When I start pt-device-manager with
/usr/lib/pt-device-manager/pt-device-manager &
I get the following:
raceback (most recent call last):
When I try to install other packages, apt tells me to do an apt --fix-broken install, and it always ends up in the removal of pt-device-manager.
So at the moment I have no more ideas.
Cheers&Thanks
Peter
python3-pitopcommon needed to be switched to all as well: https://transfer.sh/701kp/python3-pitopcommon_0.8.1-8.gbp3531e2_all.deb
With both debs in the same location, and no other debs, you can run:
sudo apt install ./*.deb
This should resolve dependencies automatically for you!
Helle Mike,
that nearly worked. I could solve some dependencies including the raspi-config package I managed to get from https://archive.raspberrypi.org/debian/pool/main/r/raspi-config/raspi-config_20200601_all.deb. Still missing is the python3-spidev package, which is not in debian … Of course it is in https://files.pythonhosted.org/packages/62/56/de649e7d95f9fcfaf965a6eb937b4a46bc77ef21487c99cde1a7a0546040/spidev-3.5.tar.gz, but it is no package and will not resolve the dependency.
Cheers
Peter
Any suggestions about the python3-spidev package?
Cheers
Peter
So when we needed a Debian package from a Python module, we have traditionally used py2deb.
However, I would probably recommend fpm now, as it seems much simpler. Check out its GitHub Wiki pages for examples on how it works, and see how you get on!
Let me know if you need more help!
OK. I am not a Debian package builder and will not become one.
So I will live with a Pi-Top without battery status control.
Thanks for bothering.
Peter
My Pi-Top battery has died some days ago. So I am no longer a Pi-Top user and quit the forum now.
Cheers
Peter
@DEACTIVATED69352686 Hi Peter, I’ve messaged you privately about getting a replacement battery to you for free. We value the time you’ve spent in the forum and would hate to see you go!
Hope to hear from you
