描述

from torchtext import data
from torchtext import datasets

TEXT = data.Field(lower=True, batch_first=True)

train, valid, test = datasets.WikiText2.splits(TEXT)

print('len(train)', len(train))

This returns a length of one. It should print the length of the whole dataset. I have tried both with version 0.2.3 and 0.3 and none of them worked.

研究方向
Investigate the implementation of the `splits` method or the WikiText2 dataset class in the torchtext library. The bug likely resides in how the dataset is loaded or split, causing only one sample to be returned. Examine the source code in the `torchtext/datasets/` directory and check for any version specific issues between 0.2.3 and 0.3. Also review any related issues or documentation to understand expected behavior.
