Help with using S3DIS

❓ Questions & Help

Hi, I am trying to use S3DIS dataset from torch geometric. So far, I downloaded the data by dataset = S3DIS(root = '../tmp/s3dis') and I checked that dataset[0] gives me 4096 sampled points. However, I don’t quite understand all the files.

Why did you separate into ‘raw’ and ‘processed’ file?
How and where can I access to test area file?

Thank you and sorry if this was a stupid question

Yes, I think so, but I’m not 100% certain anymore. Might be good to double check.

We follow torchvision here and separate the raw data and the processed data for faster loading. The processed files contain the raw files converted into the torch_geometric.data.Data format.
You can set S3DIS(..., train=False) for accessing the test data.
