在Google Colab中导入猫-vs-狗数据集时出错
提问于 2022-05-11 10:33:12
在尝试使用Cats_vs_Dogs模块下载“TensorFlow”数据集时，我得到以下错误
DownloadError Traceback (most recent call last)
<ipython-input-2-244305a07c33> in <module>()
7 split=['train[:80%]', 'train[80%:90%]', 'train[90%:]'],

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,
)它昨天起作用了，但今天突然出错了.

可以在加载之前添加此内容以设置新的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")Stack Overflow用户

这里有一个对我有用的临时解决方案，在下面用url添加
#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,
