LightningDataModule 上述Dataset是应对数据集已经划分好,到batchsize阶段的数据处理了,所以前期还需要划分数据集,Lighning框架使用pl.LightningDataModule来划分数据集,Nuplan使用的主要函数包括setup,teardown,train_dataloader,val_dataloader,test_dataloader,前两个函数在数据集开始准备和完成准备时调用,必须重载,后三个函...

Note that the standardPyTorch DataLoaderdoes not support this stateful interface. This feature only works on loaders that implement these two methods. A dataloader that supports full fault-tolerance will be included in our upcoming release of Lightning Data - a library to optimize data preprocessing ...
