'pycolmap._core.Image' object has no attribute 'id'

Hi！

Thanks for your work！

When I test VGGT-X model in our dataset, some errors happens. May I ask what is the correct pycolmap version?

This error is very common. It is a problem with the pycolmap version. It seems that you can change it to image_id, or you can view the naming rule of the Image object for id based on your pycolmap version.

so i would like to ask what version of colmap are you using

Sorry, I haven't run VGGT-X yet, but I often use pycolmaps and encounter the same problem elsewhere. I think you can check your version of pycolmap and modify the VGGT-X code to be compatible with your existing pycolmaps. The latest pycolmap seems to have replaced "id" with "image_id"

Thanks a lot!

I didn't modify the code. Simply changing the pycolmap version to 3.10.0 (matching vggt requirements) made it work properly.

It has to be said that this vggt_x is much better than vggt in the field of NVS, and it has significantly accelerated the computing speed and reduced the memory usage.What's more. Great work!
