Import error #112

Closed Krasner closed 1 year ago

Here's the error message:

from pixsfm.refine_hloc import PixSfM
Traceback (most recent call last):

I built COLMAP from source because I need CUDA support. I was able to build and use hloc and pycolmap with no problems. I built and installed ceres-2.1.0 from source, and was able to build pyceres using pip install -e . Finally, I installed pixel-perfect-sfm with pip install -e . which took a while but succeeded.

However, when trying to import pixsfm I get this error above.

Here is the ldd print out because this looks like a linker error

I figured it out. COLMAP, pyceres, pixsfm all have to be built against the ceres-solver-2.1.0. On my machine colmap was built against ceres 1.14 which did not cause an issue for pycolmap or hloc, but did cause an issue for pixsfm
