shapenet dataset error

[ssoiy]

hi, when i train this code, i got this error "ValueError : string is not a file: /path/ShapeNetCore.v2/04379243/models/model_normalized.obj" at "cubes3d.py : 131" trimesh.load function

should i change some format of shapenet?

and Do I need to create a train_labels.txt to train the shapenetcore.v2 dataset? there's no train_labels.txt in shapenet dataset

thank you

Hi @ssoiy, I fixed the harded file path in our code. Now you can put the ShapeNetCore.v2 folder (or symlink) in the local data folder, as described in the README.md now here.

There are instructions for how to download the shapenet dataset, which you can use the command wget https://shapenet.cs.stanford.edu/shapenet/obj-zip/ShapeNetCore.v2.zip --no-check-certificate for. Feel free to reopen this issue if your problems persist. Thanks!

Sorry, I still can not solve this problem, can you give some advices?

File "/home/nerfbusters/nerfbusters/data_modules/datamodule.py", line 47, in setup self.train_dataset = Cubes3D( File "/home/nerfbusters/nerfbusters/data_modules/cubes3d.py", line 79, in init with open(os.path.join(path, "train_labels.txt"), "r") as f:

FileNotFoundError: [Errno 2] No such file or directory: 'data/ShapeNetCore.v2/train_labels.txt'

Hm, so what is inside your folder data/ShapeNetCore.v2? Maybe you need to symlink it to where you installed ShapeNet?

[Harr7y]

Thanks for your reply. The data/ShapeNetCore.v2 is the dataset downloaded following the link provided in the nerfbusters. (https://shapenet.cs.stanford.edu/shapenet/obj-zip/ShapeNetCore.v2.zip)

According to the code, I think maybe the "train_labels.txt" is missed.

Hey, hm, I'm not too sure why it's not there. Here I've uploaded a copy of that file for you. Maybe that will help you?

train_labels.txt
