Just to complete this example, I commented out the statement that was causing the error and everything worked fine.

  [OctreeCreateCpu] create octree structure
  [OctreeCreateCpu] update octree data structure
  [OctreeCreateCpu] fill data
  [OctreeCreateCpu] done
pc - n_pts: 100, feature_size: 3
  [OctreeFromPC] normalize inplace
create octree
  [OctreeFromPC] determine block pts intersections for grid 8,8,8 - 100 pts
  [OctreeCreateCpu] create octree structure
  [OctreeCreateCpu] update octree data structure
  [OctreeCreateCpu] fill data
  [OctreeCreateCpu] done
pc - n_pts: 100, feature_size: 3

There seems to be a problem with some versions of Python/Cython. On my machine dense[np.newaxis,...] produces a contiguous array. However, using Anaconda it gives the error described above. I added a copy to the example to ensure a contiguous array.
