Getting and Issue with installing TEASER++

[Manohar-Manthri]

I built TEASER++ and the Python bindings . The shared object (.so) file is accessible, and I can import the module and see available classes.

Steps I followed:

Built TEASER++ normally.

In build/python, ran:

pip install .

→ Got error:

ERROR: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.

So instead, I exported the .so path to my bashrc:

export PYTHONPATH=$PYTHONPATH:/home/manu/TEASER-plusplus/build/python/teaserpp_python

Verified import works:

import _teaserpp as teaser
print(dir(teaser))

This showed classes like RobustRegistrationSolver, etc.

Problem:
When I try to access ROTATION_ESTIMATION_ALGORITHM (which is required in my project), I get the following error:

teaserpp_python.RobustRegistrationSolver.ROTATION_ESTIMATION_ALGORITHM.GNC_TLS

→ AttributeError: type object 'teaserpp_python._teaserpp.RobustRegistrationSolver' has no attribute 'ROTATION_ESTIMATION_ALGORITHM'

Expected behavior:
The Python bindings should expose ROTATION_ESTIMATION_ALGORITHM (e.g., GNC_TLS) under RobustRegistrationSolver.

System details:

OS: Ubuntu 18.04

Python: 3.6

Steps Followed to install Tesear++

git clone https://github.com/MIT-SPARK/TEASER-plusplus.git

cd TEASER-plusplus

mkdir build && cd build

CC=gcc-9 CXX=g++-9 cmake
-DTEASERPP_PYTHON_VERSION=3.6
-DBUILD_PYTHON_BINDINGS=ON
-Dpybind11_DIR=$(python3 -m pybind11 --cmakedir)
..

make teaserpp_python

In the same build

cd python
pip install .

Question:

Am I installing it right? ( I tried all methods, even using Anaconda and without Anaconda as well and followed the exact steps in the Main Git repo and the Installation guide but even those gave me the same installation results)

Is ROTATION_ESTIMATION_ALGORITHM missing in the current Python bindings, or am I accessing it incorrectly?

If it’s deprecated, what’s the correct way to set the rotation estimation algorithm in Python?

I would be very grateful for any help received

Thank You.

I encountered the same problem as you. I followed the suggestion in this link [https://github.com//issues/202#issuecomment-2943239526] to switch the branch to develop, and it solved the issue. Hope this helps you.
