hey, having the same problem:

with open(os.path.join(self.root, fn), 'rb') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'datasets/ModelNet40\\cone/train/cone_0073.ply'

All the files from ModelNet40 is .off files.

Edit: It seems that we have to figure out how to preprocess the .off files into .ply.

hello,then I just use the bash download.sh.it all finish.first, i set my code in Windows,it doesn't work. so i change the OS into Ubuntu,it really works. wish it be helpful.

I guess that the download.sh only is the source of segmentation dataset instead of modelnet40. Do you use the segmentation dataset?

download.sh contains information about shapenet dataset only. From where will we get modelnet40 dataset. I have tried manually downloading modelnet40, but when run the command got errors.

python3 train_classification.py --dataset /.../ModelNet40 --nepoch=10 --dataset_type modelnet40
Namespace(batchSize=32, num_points=2500, workers=4, nepoch=10, outf='cls', model='', dataset='home/.../ModelNet40', dataset_type='modelnet40', feature_transform=False)

apparently the dataset is offline and the manually downloaded one doesn't have the same directory buildup as the one in the repository sadly
