Why does replacing the dataset with ShapeNetPart report an error as follows.

Why does replacing the dataset in command
‘python main.py
--dataset ModelNet40
--data_path /your/path/to/dataset/
--transfer_attack_method ifgm_ours
--surrogate_model pointnet_cls
--target_model pointnet_cls
--step_size 0.007
--max_steps 50
--eps 0.16’
with ShapeNetPart report an error as follows：
‘UnboundLocalError: local variable 'batch_id' referenced before assignment’？Looking forward to your response, thanks!

Could you please provide the whole log that reports this error?

I guess it is because your data loader is an empty iterator, thus please check whether the ShapeNetPart dataset is successfully downloaded and loaded.

Thank you very much for your reply, I tried to download the dataset from somewhere else and solved the problem, but when I run srs defense command
’python main.py --dataset ModelNet40 --data_path /data/YwData/PC_work/data/modelnet40_normal_resampled/ --transfer_attack_method ifgm_ours --surrogate_model pointnet_cls --target_model pointnet_cls --defense_method srs --step_size 0.007 --max_steps 50 --eps 0.16‘
, I get the following error,
’AttributeError: 'NoneType' object has no attribute 'data'‘
but SOR as well as DUP-Net is normal, what is wrong with mine?

May I ask from which place you downloaded the ShapeNetPart dataset, I also encountered the same problem as you. The direct download with the command wget https://shapenet.cs.stanford.edu/ericyi/shapenetcore_partanno_segmentation_benchmark_v0.zip --no-check-certificate is not correct either. Thanks!
