An Error ---- 8481 chair thrown when running python sunrgbd_data.py --gen_v1_data

When I run python sunrgbd_data.py --gen_v1_data to process 10335 data, there is an image that triggers this exception Error ---- 8481 chair from

if save_votes:
            N = pc_upright_depth_subsampled.shape[0]
            point_votes = np.zeros((N,10)) # 3 votes and 1 vote mask 
            point_vote_idx = np.zeros((N)).astype(np.int32) # in the range of [0,2]
            indices = np.arange(N)

                except:
                    print('ERROR ----',  data_idx, obj.classname)   

All the other images were handled well, do you know what's wrong with it?

I have the same problem as you, not only in 8481 chair but also in 7334 desk.
