🐛 Bug

from torchtext.vocab import build_vocab_from_iterator

special_symbols = ['<unk>', '<pad>', '<bos>', '<eos>']

def yield_tokens(data_iter: Iterable) -> List[str]:
    for data_sample in data_iter:
        yield token_transform(data_sample)

train_iter = IWSLT2017(split="train")
build_vocab_from_iterator(yield_tokens(train_iter), min_freq=1, specials=special_symbols, special_first=True)

When I run above code, it shows below error:
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://drive.google.com/uc?id=12ycYSzLIG253AFN35Y6qoyf9wtkOjakp

I think some download link for the data is broken.

I just encountered this error on Google Colab.

!pip install 'portalocker'

import torch
import torch.nn as nn
import numpy as np
import matplotlib.pyplot as plt
from tqdm import tqdm

import torchtext

dataset = torchtext.datasets.IWSLT2017(root='.data', split='train', language_pair=('de', 'en'))

next(iter(dataset))
