Python 错误 : Unexpected end of data while reading a . tar 文件

Question

我正在尝试运行 TensorFlow 的 translate.py 文件，但几秒钟后我一直收到此错误:

tarfile.ReadError: unexpected end of data

我不知道为什么会发生这种情况，我尝试了几种方法，包括自己下载所需的数据并注释掉执行下载的代码行，但没有任何效果。

这是我关注的网站: https://www.tensorflow.org/tutorials/seq2seq

为了以防万一您需要一切，这里是从命令到错误的行:

C:\Users\Mueller>python translate.py

    raise exception("unexpected end of data")
tarfile.ReadError: unexpected end of data

有人知道这里发生了什么吗？

如果您的机器在代理服务器后面运行，则下载的 tar 文件可能会被代理服务器剥离/阻止，从而导致下载文件损坏。
