extractPointCloud() Method doesnt Work

[alre5639]

After building the Octomap the extractPointCloud() method always results in the following error:

occupied, empty = octree.extractPointCloud()
  File "octomap/octomap.pyx", line 505, in octomap.OcTree.extractPointCloud
  File "octomap/octomap.pyx", line 257, in __iter__
AttributeError: 'octomap.leaf_iterator' object has no attribute '_leaf_iterator__is_end'

Im thinking this is a decency issue given I cant run the setup script, any advice would be appreciated

I also encountered the same problem, have you solved it?

I was able to fix with older version of the dependencies

trimesh==3.8.11
cython==0.29.25

It's some mismatched APIs in the octomap-phthon packages. Installing this one solved my issue. pip install octomap-python==1.8.0.post11

I had the same error. I was able to fix it using:

pip install octomap-python==1.8.0.post11
pip install trimesh==3.8.11
pip install cython==0.29.25

I created a new conda environment with Python 3.8 for this and it worked.

hello devs. I have the same issue and I installed all the packages with the versions given above. still I'm getting the same error occupied, empty = octree.extractPointCloud() File "octomap/octomap.pyx", line 505, in octomap.OcTree.extractPointCloud File "octomap/octomap.pyx", line 257, in __iter__ AttributeError: 'octomap.leaf_iterator' object has no attribute '_leaf_iterator__is_end' . The list of packages in my environment is pinned below. I'm working on gym-pybullet-drones hence I had to use conda. Kindly share how to solve this pkg_list_octomap.txt
