How do I run this network to solve AttributeError: 'NoneType' object has no attribute 'items'

[mostafa501]

Hi @yuxumin, thank you for publishing this excellent work, I tried to use this model to complete my partial collected own dara.
I installed all the required libraries and solved the faced problems with previous issues. Simply i tried to inference the demo data using ("python tools/inference.py cfgs/PCN_models/AdaPoinTr.yaml ckpts/AdaPoinTr_PCN.pth --pc_root demo/ --save_vis_img --out_pc_root inference_result/") as illustrated.
However, I got this error:

Please help me to solve it, so I can test my own data after that.
Waiting your reply.
