Closed this issue · 1 comments
hello, author. When i tried to python runner.py, there were several files in the dataset that couldn't be opened. I have the following code:

Do you happen to know why? please give me some pointers, thanks!
Please double-check the path to the dataset files.
Specifically, please make sure that /home/FaceSegmentation/GRNet/datasets/ShapeNet/ShapeNetCompletion/train/complete/04256520/48228cf2207c7af5892eaa162d1e35d.pcd is on your file system.
