IndexError: index out of range

Hello, I am currently using meshcnn to do some training, using my own data set, but the initial data set is not an obj file but a stl file, I transcode the stl file and put it into the model for inference , the following error occurred at the mesh_pool layer

Traceback (most recent call last): File "/home/lyle/anaconda3/envs/fastapi/lib/python3.8/concurrent/futures/thread.py", line 57, in run result = self.fn(*self.args, **self.kwargs) File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/views/data_views.py", line 311, in data_to_milvus model_tags, model_ids, file_embs, mesh_embs = get_bin_embs(uvnet_model, save_loader, File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/views/data_views.py", line 164, in get_bin_embs mesh_embs = meshcnn_model.get_emb() File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/MeshCNN_Collection/models/mesh_classifier.py", line 56, in get_emb _, emb = self.net(self.edge_features, self.mesh) File "/home/lyle/anaconda3/envs/fastapi/lib/python3.8/site-packages/torch/nn/modules/module.py", line 1130, in _call_impl return forward_call(*input, **kwargs) File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/MeshCNN_Collection/models/networks.py", line 142, in forward x = getattr(self, 'pool{}'.format(i))(x, mesh) File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/MeshCNN_Collection/models/layers/mesh_pool.py", line 23, in __call__ return self.forward(fe, meshes) File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/MeshCNN_Collection/models/layers/mesh_pool.py", line 36, in forward self.__pool_main(mesh_index) File "/home/lyle/桌面/FDU/UVNET_FastServer_previous/app/../app/MeshCNN_Collection/models/layers/mesh_pool.py", line 52, in __pool_main value, edge_id = heappop(queue) IndexError: index out of range

After my observation, it seems that the edge_count failed to -1 in the __pool_edge method.
def __pool_edge(self, mesh, edge_id, mask, edge_groups): if self.has_boundaries(mesh, edge_id): return False elif self.__clean_side(mesh, edge_id, mask, edge_groups, 0)\ and self.__clean_side(mesh, edge_id, mask, edge_groups, 2) \ and self.__is_one_ring_valid(mesh, edge_id): self.__merge_edges[0] = self.__pool_side(mesh, edge_id, mask, edge_groups, 0) self.__merge_edges[1] = self.__pool_side(mesh, edge_id, mask, edge_groups, 2) mesh.merge_vertices(edge_id) mask[edge_id] = False MeshPool.__remove_group(mesh, edge_groups, edge_id) mesh.edges_count -= 1 return True else: return False # mesh.edges_count -= 1 return True

But almost 80% of my transcoding files have such errors. For these files, the edge_count will not be reduced by 1 at all. How to fix such errors?

The following is an obj sample of an error
