ValueError: setting an array element with a sequence.

I would very appreciate it if you can help me run code

trunk_pcd_path, branch_pcd_path = downloader.download_semantic_tree_dataset()

pcd_trunk = o3d.io.read_point_cloud(trunk_pcd_path)
pcd_branch = o3d.io.read_point_cloud(branch_pcd_path)
pcd = pcd_trunk + pcd_branch
#  
lbc = LBC(point_cloud=pcd,
          down_sample=0.008)
lbc.extract_skeleton()
lbc.extract_topology()
lbc.visualize()
lbc.show_graph(lbc.skeleton_graph)
lbc.show_graph(lbc.topology_graph)
lbc.save('./output')
lbc.animate(init_rot=np.asarray([[1, 0, 0], [0, 0, 1], [0, 1, 0]]),
            steps=300,
            output='./output')

The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (17,) + inhomogeneous part.
