Liveplotter on OSX - No Anaconda

Support
1

Hi All, I’ve always had trouble running liveplotter on my ODrivetool installation and curious if I could get some feedback. I have the same error as below running the liveplotter command from the command line or in the ODrivetool CLI. This error appears and a python icon opens in my OSX Dock attempting to launch, but not much more than that happens. As title implies this is a straight install from the command line without the use of anaconda. Using ODrive control utility v0.5.1

In [106]: start_liveplotter(lambda: [odrv0.axis0.encoder.pos_estimate])

I am having exactly the same issue.

I haven’t found a solution to this @nomas . We’ve just been using arduino liveplottler instead to reading odrive values over serial. Not ideal, but it works out of the box if you’re using serial communication.

same exact issue :frowning: Hope someone can help out with this

Sorry, Liveplotter doesn’t work on OSX. Try the GUI or write a custom plotter :slight_smile:
