我正在尝试在 Linux 上运行本教程。我安装了gcc, cython, numpy, six.

我可以导入数据，但解包似乎存在某种问题。

任何人都可以帮忙吗？

Python 2.7.3 (default, Jun 22 2015, 19:43:34)
[GCC 4.6.3] on linux2

>>> import g3doc.tutorials.mnist.input_data as input_data
>>> mnist = input_data.read_data_sets("MNIST_data/", one_hot=True)

这似乎是最新版本的 Numpy 的问题。最近的一项更改使得将单元素数组视为标量以进行索引是错误的。

我已对上游 TensorFlow 代码进行了相关更改，但同时您可以将(L45) 中的这一行input_data.py[0]编辑为以下内容（在行尾添加）：

return numpy.frombuffer(bytestream.read(4), dtype=dt)[0]
