python – notMNIST不能在TensorFlow Udacity课程中下载

我正在做Udacity TensorFlow课程,第一次练习：https://github.com/tensorflow/tensorflow/blob/master/tensorflow/examples/udacity/1_notmnist.ipynb

OSX 10.11(El Capitan)
Python 2.7
virtualenv安装TF

我收到一个错误：

“例外：verifynotMNIST_large.tar.gz失败.你能用浏览器搞定吗？”

它找到了“小”文件,但不是“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

解决方法:

也面临同样的情况.

处理它并继续这是一件简单的事情.

There’s a size mismatch.

Just re-run the code with force=True, and
it works right Now!

如果您尝试手动下载它也将是好的.
