Import errors and solutions for running TreeXAlgorithm

[hagreven]

Thank you for the great work! I’ve been testing the improved TreeXAlgorithm, but ran into a few issues when installing the required packages using:

pip install pointtree circle_detection

This led to the following import errors:

cannot import name 'TreeXAlgorithm' from 'pointtree.instance_segmentation'

cannot import name 'MEstimator' from 'circle_detection'

It seems that the versions currently available on PyPI are not up-to-date and missing recent changes. To resolve this, I cloned the latest versions of both repositories and installed them as editable modules:

git clone https://github.com/ai4trees/pointtree.git
pip install -e pointtree

git clone https://github.com/josafatburmeister/circle_detection.git
pip install -e circle_detection

This resolved the initial import errors. However, I then encountered another:

cannot import name 'TreeXPresetTLS' from 'pointtree.instance_segmentation'

This is caused by a missing import in pointtree/instance_segmentation/__init__.py.
Adding the following line resolves it:

from .tree_x_presets import *

With that everything else ran smoothly.

Thanks for your feedback and the fix! I’ve now released a new version of pointtree that resolves these installation and import issues.

You can install it using:

python -m pip install torch==2.10.0
python -m pip install torch-scatter torch-cluster -f https://data.pyg.org/whl/torch-2.10.0+cpu.html
python -m pip install pointtree
