Python '；utf-8'；tensorflow教程中的解码错误

我遇到了一个奇怪的问题当我跑步的时候

  from tensorflow.examples.tutorials.mnist import input_data

  mnist = input_data.read_data_sets('/home/fqiao/development/MNIST_data/', one_hot=True)

我得到：

  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/dist-packages/tensorflow/examples/tutorials/mnist/input_data.py", line 199, in read_data_sets
    train_images = extract_images(local_file)
  File "/usr/local/lib/python3.5/dist-packages/tensorflow/examples/tutorials/mnist/input_data.py", line 58, in extract_images
    magic = _read32(bytestream)
  File "/usr/local/lib/python3.5/dist-packages/tensorflow/examples/tutorials/mnist/input_data.py", line 51, in _read32
    return numpy.frombuffer(bytestream.read(4), dtype=dt)[0]
  File "/usr/lib/python3.5/gzip.py", line 274, in read
    return self._buffer.read(size)
  File "/usr/lib/python3.5/_compression.py", line 68, in readinto
    data = self.read(len(byte_view))
  File "/usr/lib/python3.5/gzip.py", line 461, in read
    if not self._read_gzip_header():
  File "/usr/lib/python3.5/gzip.py", line 404, in _read_gzip_header
    magic = self._fp.read(2)
  File "/usr/lib/python3.5/gzip.py", line 91, in read
    self.file.read(size-self._length+read)
  File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/platform/default/_gfile.py", line 45, in sync
    return fn(self, *args, **kwargs)
  File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/platform/default/_gfile.py", line 199, in read
    return self._fp.read(n)
  File "/usr/lib/python3.5/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte

有人知道发生了什么吗

我的系统：Ubuntu15.10 x64 python 3.5.0。

最近的一项更改解决了这个错误。MNIST文件需要以二进制“rb”模式打开，而不仅仅是文本“r”。

在我的例子中，问题在于数据文件的编码

使用

vim

打开文件并执行：

:set fileencoding=utf-8

这解决了我的问题。

似乎存在文本编码问题，请检查文件的文本编码

:set fileencoding=utf-8
