TypeError: 'ListWrapper' object is not iterable

I met:

  File "/mnt/sharedata/hdd/zhouxn/ICLCP/group_distance_k.py", line 33, in group_with_distance
    retriever = TopkRetriever(data, ice_num=3, batch_size=args.batch_size, index_split='train', test_split='test')
  File "/mnt/sharedata/hdd/zhouxn/ICLCP/openicl/icl_retriever/icl_topk_retriever.py", line 78, in __init__
    self.index = self.create_index()
  File "/mnt/sharedata/hdd/zhouxn/ICLCP/openicl/icl_retriever/icl_topk_retriever.py", line 86, in create_index
    res_list = self.forward(dataloader, process_bar=True, information="Creating index for index set...")
  File "/mnt/sharedata/hdd/zhouxn/ICLCP/openicl/icl_retriever/icl_topk_retriever.py", line 114, in forward
    res_list.extend([{"embed": r, "metadata": m} for r, m in zip(res, metadata)])
TypeError: 'ListWrapper' object is not iterable

I wonder what will cause this error?
