ZeroDivisionError: float division by zero

[Boyan]

Hi everyone!
I’ve installed DisplayCal on MacOS Sonoma (using the Pyton 3.x version) and I am trying to calibrate my external monitor by creating a 3D LUT for Davinci Resolve.

At the end of the calibration process (no matter what size testchart I choose) I always get the same error message: “ZeroDivisionError: float division by zero”

When I do the calibration on MacOS Ventura there are no issues and I do not get this message.

Do you have any ideas on what I can do to fix this issue to be able to properly calibrate my external monitor on Sonoma?
I’ve attached the log file if it can be of any help.

Thank you!

Just troubleshooting guess.   I do not have MacOS.     It could be permissions.     Some folders can be accessed by system but not users.    Can you give yourself admin access temporally?    hm   Working directory is in VAR and I only rememeber permission issues way back trying Debain Linux.    I got su to work and could finally access my video and audio devices.     Not sure what to do with display Cal to help.

-if you have the ti3 file and the .cal file (if you add calibration) you can try to create manually the icc profile with ArgyllCMS commandline.
Actually you can try to do the whole process this way if there is no fix: dispcal (.cal with VCGT), dispread (apply .cal, read patches fro profilling in a ti3 file), colprof (to make ICC profile from .ti3 and .cal), collink (for generating LUT3D)

-DisplayCAL-py3 issues need to be reported in Erkan’s Github
https://github.com/eoyilmaz/displaycal-py3/issues
or at least write them in the DisplayCAL-py3 thread. Otherwise Erkan’s won’t notice it.
