🐛 Bug

Describe the bug

requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-2-v1.zip
This exception is thrown by iter of HTTPReaderIterDataPipe(skip_on_error=False, source_datapipe=OnDiskCacheHolderIterDataPipe, timeout=None)

To Reproduce Steps to reproduce the behavior:

from torchtext.datasets import WikiText2
from torchtext.data.utils import get_tokenizer
from torchtext.vocab import build_vocab_from_iterator
from torch.utils.data import DataLoader, Dataset

tokenizer = get_tokenizer("basic_english")

train_iter = WikiText2(split='train')
valid_iter = WikiText2(split='valid')

def yield_tokens(data_iter):
for item in data_iter:
yield tokenizer(item)

vocab = build_vocab_from_iterator(yield_tokens(train_iter),
specials=["", "", ""])
vocab.set_default_index(vocab[""])

Expected behavior A clear and concise description of what you expected to happen.

Is there an alternate link we can get? The documentation here says:

import os
from functools import partial
from typing import Union, Tuple

from torchtext._internal.module_utils import is_module_available
from torchtext.data.datasets_utils import (
    _wrap_split_argument,
    _create_dataset_directory,
)

URL = "https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-2-v1.zip"

MD5 = "542ccefacc6c27f945fb54453812b3cd"

... can we just find an alternate URL and change the function?

Hi team, about this error, is there any solution now? We also encountered the same error.

[WangX0111]

how can we change the URL

[ihainan]

I uploaded the wikitext-2-v1.zip file to my server and changed the source code lines in the lib/python3.10/site-packages/torchtext/datasets/wikitext2.py file from:

URL = "https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-2-v1.zip"
MD5 = "542ccefacc6c27f945fb54453812b3cd"

to

URL = "http://la.ihainan.me/wikitext-2-v1.zip"
MD5 = "f6e734fc17885b364243f67b30385a3d"

to temporarily solve this issue.
