python - notMNIST 无法在 TensorFlow Udacity 类(class)中下载

Question

我正在学习 Udacity TensorFlow 类(class)，第一个练习:https://github.com/tensorflow/tensorflow/blob/master/tensorflow/examples/udacity/1_notmnist.ipynb

OSX 10.11(埃尔卡皮坦)Python 2.7TF的virtualenv安装

我收到一个错误:

“异常:无法验证notMNIST_large.tar.gz。你能用浏览器访问它吗？”

它找到“小”文件，但找不到“大”文件。感谢帮助。谢谢。

这是整个代码块:

>>> url = 'http://yaroslavvb.com/upload/notMNIST/'
>>> 
>>> def maybe_download(filename, expected_bytes):
...   """Download a file if not present, and make sure it's the right size."""
...   if not os.path.exists(filename):
...     filename, _ = urlretrieve(url + filename, filename)
...   statinfo = os.stat(filename)
...   if statinfo.st_size == expected_bytes:
...     print('Found and verified', filename)
...   else:
...     raise Exception(
...       'Failed to verify' + filename + '. Can you get to it with a browser?')
...   return filename
... 

这是返回的内容:

 >>> train_filename = maybe_download('notMNIST_large.tar.gz', 247336696)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 10, in maybe_download
Exception: Failed to verifynotMNIST_large.tar.gz. Can you get to it with a browser?
>>> test_filename = maybe_download('notMNIST_small.tar.gz', 8458043)
Found and verified notMNIST_small.tar.gz

同样面临同样的情况。

处理它并继续是一件简单的事情。

There's a size mismatch.

Just re-run the code with force=True, andit works right now!

如果您尝试手动下载它也可以。
