Python的错误：数据意外结束而读.tar文件

Question

我试图运行TensorFlow的translate.py文件，但已经几秒钟后，我不断收到此错误：

tarfile.ReadError: unexpected end of data 

我没有想法为什么发生这种情况，我尝试了几件事，包括自己下载所需的数据，并在下载代码中注释该行，但没有任何工作。

这里是我按照网站： https://www.tensorflow.org/tutorials/seq2seq

以防万一你需要的一切，这里是从命令到错误的线：

有谁知道发生了什么这里？

如果您的机器运行在代理服务器后面，则可能下载的tar文件可能被代理服务器剥离/阻塞，导致下载文件损坏。
