zsh: bus error cfclient when Estimate Geometry with Lighthouse

[r-bt]

I have setup two v2 Lighthouse base stations and was going through the Estimate Geometry flow. However upon pressing the Estimate Geometry button at the end (shown in fig):

The cfclient immediately crashed and in the console I get the error:

zsh: bus error  cfclient

I managed to run the calibration on M1 with brew installed Python 3.12 with latest client and lib installed through pip.

Can you share some more information like what OS you are running, and Python, cfclient and cflib version?

[r-bt]

I am using

• macOS 14.4
• Python 3.11.7 (I tried using 3.12.0 but I couldn't see any USB devices in cfclient)
• Cfclient 2024.3
• Cflib 0.1.25.1

Hi!

We need some more information aobut:

The cfclients's debug tab (found under 'Help'>'about') has more information your development environment and your connected Crazyflie, so could you copy past that here?

@r-bt @dizzy-s Thanks for the system information, I managed to reproduce the problem on an M1 mac with Python 3.11. I will investigate the problem and attempt to solve it.

I created an issue in the client repos, I cannot see a quick easy fix for it so for now using another computer would be the best bet unfortunatly. Maybe installing brew/python for x86 using rosetta might help, but I have not had time to test yet.
