3 months ago Hi @YangZiz.
There might be two reasons:
- LMDB files are corrupted, you may need to re-download it.
- The version of msgpack version is not correct, see OcCo_Torch/Requirements_Torch.txt
Hi@hansen7 : When I run on my own dataset, the following errors occur. What should I do
Traceback (most recent call last): File "./OcCo_Torch/train_completion.py", line 253, in <module> main(args) File "./OcCo_Torch/train_completion.py", line 71, in main lmdb_train, args.batch_size, args.input_pts, args.gt_pts, is_training=True) File "/workspace/OcCo_Torch/OcCo_Torch/LMDB_DataFlow.py", line 77, in lmdb_dataflow df = dataflow.LMDBSerializer.load(lmdb_path, shuffle=False) File "/opt/conda/lib/python3.6/site-packages/tensorpack/dataflow/serialize.py", line 106, in load df = LMDBData(path, shuffle=shuffle) File "/opt/conda/lib/python3.6/site-packages/tensorpack/dataflow/format.py", line 91, in __init__ self._set_keys(keys) File "/opt/conda/lib/python3.6/site-packages/tensorpack/dataflow/format.py", line 111, in _set_keys self.keys = loads(self.keys) File "/opt/conda/lib/python3.6/site-packages/tensorpack/utils/serialize.py", line 43, in loads_msgpack max_str_len=MAX_MSGPACK_LEN) File "/opt/conda/lib/python3.6/site-packages/msgpack_numpy.py", line 287, in unpackb return _unpackb(packed, **kwargs) File "msgpack/_unpacker.pyx", line 201, in msgpack._cmsgpack.unpackb msgpack.exceptions.ExtraData: unpack(b) received extra data.
