Hello author, I set up the same environment as in the article, but I get the following error, can you please help me?

Traceback (most recent call last): File "preprocess_ogbn_mag.py", line 18, in dataset = PygNodePropPredDataset(name='ogbn-mag') File "/root/miniconda3/envs/myconda/lib/python3.7/site-packages/ogb/nodeproppred/dataset_pyg.py", line 46, in init super(PygNodePropPredDataset, self).init(self.root, transform) File "/root/miniconda3/envs/myconda/lib/python3.7/site-packages/torch_geometric/data/in_memory_dataset.py", line 52, in init pre_filter) File "/root/miniconda3/envs/myconda/lib/python3.7/site-packages/torch_geometric/data/dataset.py", line 104, in init self._process() File "/root/miniconda3/envs/myconda/lib/python3.7/site-packages/torch_geometric/data/dataset.py", line 148, in _process self.process() File "/root/miniconda3/envs/myconda/lib/python3.7/site-packages/ogb/nodeproppred/dataset_pyg.py", line 153, in process torch.save(self.collate([data]), self.processed_paths[0]) File "/root/miniconda3/envs/myconda/lib/python3.7/site-packages/torch_geometric/data/in_memory_dataset.py", line 137, in collate raise ValueError('Unsupported attribute type') ValueError: Unsupported attribute type
