Describe the problem
In feature extraction, cctag3 has a red light. Attached is the picture below.

Screenshots

Desktop (please complete the following and other pertinent information):

• OS: Ubuntu 24.04
• Python version 3.9.13
• Qt/PySide version 5.15.2
• Meshroom version: 2025.1.0

Did you run the node with cctag only to see if that works?

@natowi
Could you please elaborate a little more?
It's my first time with meshroom, so it's hard

I see the same problem. It fails also with only cctag3 enabled. In the logs it shows this message:

[10:07:20.542326][fatal] Invalid imageDescriber : cctag3

@natowi
As you said, the problem also occurs when only CCTag is set up and executed.
But I run except CCTag and it works fine.

Do you have any other ideas?

@hiaselhans @natowi
Maybe the version distributed in 25 is problematic.
It goes back to the 23rd year version without any problems when running the code.

@natowi could you reproduce the issue?

[natowi]

I´ve tested the cctag extraction and it works (for me, on Windows). I will prepare a pipeline template to share.
Sorry for the late reply, I was busy with my job.

You can download a Photogrammetry CCTAG Template here: https://raw.githubusercontent.com/alicevision/AliceVision/88c2c777e68c0cf2fbefa5c62aac6854d93e7c84/meshroom/photogrammetry-cctag.mg
(You need to adjust the marker values in the CCTAG "SfMTransform CCTAG Sizing" and "SfMTransform from CCTAG" nodes.)

Thank you for your response.
But there's still a problem
I'm working on Ubuntu.
I think this problem only occurs in linux.
Can you implement this issue in ubuntu?
