我使用Python 3.5.2在Windows上安装了Tensorflow;当我尝试运行board.py文件时，我收到超时错误。我在试图运行的一些tensorflow脚本上遇到此错误。是什么导致了这个错误，我该如何解决？

在http://yann.lecun.com/exdb/mnist/托管的MNIST数据集目前似乎处于离线状态。不幸的是，该URL似乎在各种示例文件中都是硬编码的，但您可以尝试将其更改为此pull request中列出的其中一个镜像：

请注意，您可以手动将文件下载到input_data.read_data_sets()调用中指定的临时目录（在您的情况下，这似乎是/tmp/data/）。如果阅读器代码在该位置找到文件，则不会尝试联系服务器。
