Python的錯誤：數據意外結束而讀.tar文件

Question

我試圖運行TensorFlow的translate.py文件，但已經幾秒鐘後，我不斷收到此錯誤：

tarfile.ReadError: unexpected end of data 

我沒有想法爲什麼發生這種情況，我嘗試了幾件事，包括自己下載所需的數據，並在下載代碼中註釋該行，但沒有任何工作。

這裏是我按照網站： https://www.tensorflow.org/tutorials/seq2seq

以防萬一你需要的一切，這裏是從命令到錯誤的線：

有誰知道發生了什麼這裏？

如果您的機器運行在代理服務器後面，則可能下載的tar文件可能被代理服務器剝離/阻塞，導致下載文件損壞。
