Our BaseDataset
class inherits from torch-geometric and rules how raw and preprocessed data are organized.
The behavior of the datasets (and the answer to your question) is explained in the datasets documention. Please have a look.
Also, when instantiating a dataset, the logs explicitly tell you where the preprocessed data is stored.
PS: One important novelty of our BaseDataset
class compared to torch-geometric is that we compute a hash to characterize the pre_transform
(ie all the preprocessing steps) of a dataset. We use this hash to uniquely identify the preprocessing recipe you have used when first instantiating a dataset, which prevents recomputing / overwriting yoir preprocessed files when instantiating your dataset with a slightly different preprocessing reciper later on.
Hello, I have recently been studying your method. Since I haven't touched Pytorch_lighting very much before, can you tell me where is the data preprocessing department in your program?
