GPU: Bundle_Adjuster of Colmap 311

[HungNgoCT]

Hi,

I saw that there is an option: --BundleAdjustment.use_gpu (0/1) for bundle_adjuster. But when I set 1, it seems bundle adjustment does not run on GPU.

I choose correct GPU index, and GPU is used for extract features and matching

I am wondering if Colmap 311 supports BA using GPU or not?

Thank you
