THE Structure #25

Open Bigbigyaoyao opened 1 month ago

Bigbigyaoyao commented 1 month ago

Hello, I'm new in the field of analysis of Point Cloud.

And,I wonder how I should organize the structure of data after downloading the zip file you have provided.

When I only unzip ShapeNet55 and put it in ./data/ShapeNet55-34 and then start to pretrain the Point-S ,it show the error that"FileNotFoundError: ShapeNet: [Errno 2] No such file or directory: 'data/ShapeNet55-34/ShapeNet-55/train.txt'". And I wonder whether I need to create new test and train folders or not, and I want to know how the files should be arranged.

And Here's the structure of my file │ShapeNet55-34/ ├──shapenet_pc/ │ ├── 02691156-1a04e3eab45ca15dd86060f189eb133.npy │ ├── 02691156-1a6ad7a24bb89733f412783097373bdc.npy │ ├── ....... ├──ShapeNet-55/ │ ├── │ └──

Wish for response!
