UAVCAN GUI Tool Installation Errors

[Jonathan Wittmer]

Hello Everyone,

I am trying to install the UAVCAN GUI Tool on the Raspberry Pi 3. As far as I know, no one has successfully done this yet. When I first tried to install it, there were complaints that I did not have/could not get pyqt5 and thus the front end would not work. I have since downloaded that library and that error is gone. However, When I run [CODE]sudo pip3 install git+https://github.com/UAVCAN/gui_tool@master[/CODE], the installation errors out at [CODE]Collecting pyyaml>3.10[/CODE] with an HTTP error 404. 

Is this occurring because I am trying to install it on the Raspberry Pi or is there something else I am doing wrong here?

Thanks,

Jon

Sorry for the poor formatting above.

 Update: I manually installed the pyyaml package and the installation proceeded smoother, but I am still receiving errors. This time the errors are

http.client.RemoteDisconnected.

I tried running the installation several times and each time I get this error at a different spot. Also, there does not seem to be any pattern to when I get this error as sometimes it will happen earlier in the process than others. I assume that this is due to an issue with my internet connection. 

If this is indeed the case, is there a way to manually download and install the GUI tool? I tried downloading the git directory and running

sudo python3 setup.py

 but I got a fatal error of

Not a git repository (or any of the parent directories)

Thanks,

Jon

Hi Jonathan,

In order to fix the last error, clone the whole git repository and then initialize the submodules. Plain zip archives won't work.

git clone --recursive https://github.com/UAVCAN/gui_tool

Hope this helps.

Pavel.

Hi Pavel,

I did as you suggested and that solved the errors I was getting. However, it seems that the GUI tool is not being installed. I checked /usr/local/bin for the program and I cannot find it. I ran setup.py from the main directory of the download after unzipping the folder. Is there another script that I am supposed to run to install the tool? Or maybe it got installed in a different directory?

Thanks,

Jon

Can't reproduce; running "sudo pip3 install ." should be sufficient. On my machine it is installed as /usr/local/bin/uavcan_gui_tool:

pavel@pavel-workstation $ which uavcan_gui_tool 
/usr/local/bin/uavcan_gui_tool

Try searching your drive for uavcan_gui_tool; if that didn't help, try reinstalling it from scratch and inspect the pip output for errors.

Pavel.

Ahh that is what I was missing. I was not using the "pip3 install" command. After running that, I was able to install the tool on my raspberry pi. I will be testing it out later today.




Thanks for the help.
