在尝试使用tfds模块下载“Cats_vs_Dogs”TensorFlow数据集时，我收到以下错误消息：

DownloadError                             Traceback (most recent call last)
<ipython-input-2-244305a07c33> in <module>()
      7     split=['train[:80%]', 'train[80%:90%]', 'train[90%:]'],
      8     with_info=True,
----> 9     as_supervised=True,
     10 )

21 frames
/usr/local/lib/python3.7/dist-packages/tensorflow_datasets/core/download/downloader.py in _assert_status(response)
    257   if response.status_code != 200:
    258     raise DownloadError('Failed to get url {}. HTTP code: {}.'.format(
--> 259         response.url, response.status_code))

DownloadError: Failed to get url https://download.microsoft.com/download/3/E/1/3E1C3F21-ECDB-4869-8368-6DEBA77B919F/kagglecatsanddogs_3367a.zip. HTTP code: 404.

我使用的代码是

import tensorflow_datasets as tfds
tfds.disable_progress_bar()

# split the data manually into 80% training, 10% testing, 10% validation
(raw_train, raw_validation, raw_test), metadata = tfds.load(
    'cats_vs_dogs',
    split=['train[:80%]', 'train[80%:90%]', 'train[90%:]'],
    with_info=True,
    as_supervised=True,
)

昨天还能用，今天突然出错了.......

您可以在加载之前添加此内容以设置新URL：

setattr(tfds.image_classification.cats_vs_dogs, '_URL',"https://download.microsoft.com/download/3/E/1/3E1C3F21-ECDB-4869-8368-6DEBA77B919F/kagglecatsanddogs_5340.zip")

这里是一个临时的解决方案，为我工作，下面添加一行网址

#Added code
    
        setattr(tfds.image_classification.cats_vs_dogs, '_URL',"https://download.microsoft.com/download/3/E/1/3E1C3F21-ECDB-4869-8368-6DEBA77B919F/kagglecatsanddogs_5340.zip")
        
   
#Initial code that failed with the error
        
        (train_examples, validation_examples), info = tfds.load(
            'cats_vs_dogs',
            split=['train[:80%]', 'train[80%:]'],
            with_info=True,
            as_supervised=True,
        )

#Complete code together

setattr(tfds.image_classification.cats_vs_dogs, '_URL',"https://download.microsoft.com/download/3/E/1/3E1C3F21-ECDB-4869-8368-6DEBA77B919F/kagglecatsanddogs_5340.zip")
(train_examples, validation_examples), info = tfds.load(
    'cats_vs_dogs',
    split=['train[:80%]', 'train[80%:]'],
    with_info=True,
    as_supervised=True,
)

从昨天开始就不行了

看起来他们改变了URL，忘记了tensorflow数据集：-（

只需更新已安装的tensorflow_datasets软件包。

显示为“DownloadError”。这可能是关于你的互联网连接或你已经达到了谷歌可乐一天的下载限制。
