PyTorchText Bucket Iterator Dataloader. Here is where the magic happens! We pass in the train_dataset and valid_dataset PyTorch Dataset splits into BucketIterator to create the actual batches.. It's very nice that PyTorchText can handle splits! No need to write same line of code again for train and validation split.
