AttributeError: module 'pycolmap' has no attribute 'patch_match_stereo' #2457

I tried to run the example code in this link https://github.com/colmap/pycolmap?tab=readme-ov-file , but I got the following error:

output_path: pathlib.Path
image_dir: pathlib.Path

output_path.mkdir()
mvs_path = output_path / "mvs"
database_path = output_path / "database.db"

pycolmap.extract_features(database_path, image_dir)
pycolmap.match_exhaustive(database_path)
maps = pycolmap.incremental_mapping(database_path, image_dir, output_path)
maps[0].write(output_path)
# dense reconstruction
pycolmap.undistort_images(mvs_path, output_path, image_dir)
pycolmap.patch_match_stereo(mvs_path)  # requires compilation with CUDA
pycolmap.stereo_fusion(mvs_path / "dense.ply", mvs_path)

AttributeError: module 'pycolmap' has no attribute 'patch_match_stereo'

How can I fix it?

According to the comment on the relevant line you need to compile with CUDA:

pycolmap.patch_match_stereo(mvs_path) # requires compilation with CUDA

Hello there, I've been trying to solve this issue for a while now, but even though I'm pretty sure im building colmap from source with CUDA, this function still doesn't work. Is there anything that can tell me exactly when pycolmap is aware that it's using a certain COLMAP install?

The comment by Linusnie on this thread helped me out. https://github.com/colmap/colmap/issues/2481# I forgot that you also have to setup pycolmap through the version found inside the colmap folder (can't use pycolmap installed separately, at least I couldn't get that to work).
