Hi!

I have installed plotjuggler using apt with

$ sudo apt install ros-melodic-plotjuggler

Running the application with

$ plotjuggler

shows the 'loading meme' very briefly, but then quits and shows the following error:

The application worked earlier today but stopped working after an attempt to install some dependencies for keras/tensorflow. The error message I get doesn't really help me which is why I am posting here.

I am using Ubuntu 18.04. I already tried reinstalling and rebooting multiple times.

If you need any other information I'll be happy to provide it.

Thanks!

Hello,

Same distro and same issue! Recently updated plotjuggler to the newest version!

[SDBonhof]

I have found the same error at #346. Seems like something might have gone wrong with a recent update.

[facontidavide]

Can you please compile the matest vesion in branch main and tell me if the problem persists?

[flaavour]

Seems the latest main fixes the issue.

[facontidavide]

great. Enjoy plotJuggler 3.

The Debian package will take a couple of weeks to be released by OpenRobotics, in the midtime, the README has instruction to compile it yourself.
