当我尝试通过打印对象的下一个迭代来查看批次时BucketIterator，AttributeError会抛出 。

tv_datafields=[("Tweet",TEXT), ("Anger",LABEL), ("Fear",LABEL), ("Joy",LABEL), ("Sadness",LABEL)]
train, vld = data.TabularDataset.splits(path="./data/", train="train.csv",validation="test.csv",format="csv", fields=tv_datafields)

train_iter, val_iter = BucketIterator.splits(
(train, vld),
batch_sizes=(64, 64),
device=-1,
sort_key=lambda x: len(x.Tweet),
sort_within_batch=False,
repeat=False
)
print(next(iter(train_dl)))
