Type Error with reconstruction object

[bdxuyidong]

Hi. Thanks for your work. I met some problems running the Demo at:
refined, sfm_outputs = sfm.reconstruction(ref_dir, images, sfm_pairs, features, matches, image_list=references)
The output is:
File /pixel-perfect-sfm/pixsfm/bundle_adjustment/main.py:133, in FeatureReferenceBundleAdjuster.refine(self, reconstruction, feature_set, problem_setup)
131 print(reconstruction)
132 #
--> 133 feature_view = features.FeatureView(
134 feature_set,
135 reconstruction
136 )
138 # Schedule reference computation (label for each point3D)
139 problem_labels = find_problem_labels(reconstruction,
140 self.conf.max_tracks_per_problem)

TypeError: FeatureView(): incompatible function arguments. The following argument types are supported:
1. (feature_set: pixsfm._pixsfm._features.FeatureSet_f16, reconstruction: colmap::Reconstruction) -> pixsfm._pixsfm._features.FeatureView_f16

12. (feature_set: pixsfm._pixsfm._features.FeatureSet_f32, graph: pixsfm._pixsfm._base.Graph) -> pixsfm._pixsfm._features.FeatureView_f32

15. (feature_set: pixsfm._pixsfm._features.FeatureSet_f32, reconstruction: colmap::Reconstruction, point3D_ids: Set[int]) -> pixsfm._pixsfm._features.FeatureView_f32

Invoked with: ,

It seems that the object 'reconstruction' is the wrong type before enter into features.FeatureView(), I also output feature_set
and reconstruction, they are:
<pixsfm._pixsfm._features.FeatureSet_f16 object at 0x7f876e078870>
<Reconstruction 'num_reg_images=10, num_cameras=10, num_points3D=1852, num_observations=8071'>

By the way, I can run the raw reconstruction without refinement. Please help me with the problem, thank you.

Hi again :) This seems to be a linking error between pycolmap and pixsfm. Did you check that also pycolmap is installed from source?

Got it also

Is there corresponding solution towards this problem?

Hello, the issue is caused by version mismatch. Hierarchical-Localization should be version 1.4, and pycolmap should be version 0.4.0. You should install the corresponding versions from the source instead of directly cloning the repository, as the cloned version of hloc is not 1.4.
