lamar.tasks.pose_estimation | RecursionError: maximum recursion depth exceeded while calling a Python object

[mihaidusmanu]

Hello. This is related to some strange pybind behavior related to the PyCOLMAP bindings. Increasing the recursion length does not fix it. Are you using the pip PyCOLMAP package or are you compiling from sources?

I would suggest compiling the latest version of PyCOLMAP from sources.

Hello. Thank you for your reply.
I used pip PyCOLMAP, but I fixed it after compiling from sources.

I leave the code for setting up the dependencies.

hloc

git clone --recursive https://github.com/cvg/Hierarchical-Localization/
cd Hierarchical-Localization
python -m pip install -e .

COMAP

git clone https://github.com/colmap/colmap.git
cd colmap
git checkout dev
mkdir build
cd build
cmake ..
make -j
sudo make install

PyCOLMAP

git clone --recursive https://github.com/colmap/pycolmap.git
cd pycolmap
python -m pip install -e .

Ceres

• http://ceres-solver.org/installation.html#linux
• Use Ceres Solver 2.1.
• Because Ceres Solver 2.2 requires a fully C++17-compliant compiler, whereas PyColmap requires c++14.
