Python Error: Unexpected end of data while reading a .tar file

I'm trying to run TensorFlow's translate.py file, but after a few seconds already I keep getting this error:

tarfile.ReadError: unexpected end of data

I have no idea why this happens and I've tried several things, including downloading the needed data myself and comment the line in the code that do the downloading, but nothing worked.

Here is the site that I follow: https://www.tensorflow.org/tutorials/seq2seq

And just in case you need everything, here are the lines from the command to the error:

C:\Users\Mueller>python translate.py

 line 243, in copyfileobj
    raise exception("unexpected end of data")
tarfile.ReadError: unexpected end of data

Does anybody know what is happening here?

If your machine is running behind a proxy server, its possible that the downloaded tar file maybe getting stripped/blocked by proxy server, resulting in corrupted downloaded file.
