Issue: Dataset download error
Hi @XuhuiZhou, thanks for reporting this issue. 

Indeed, the old links are no longer valid (404 Not Found error), and the script must be updated with the new links to Google Drive.
The download link in `iwslt2017.py` file does not seem to work anymore.

For example, `FileNotFoundError: Couldn't find file at https://wit3.fbk.eu/archive/2017-01-trnted/texts/zh/en/zh-en.tgz`

Would be nice if we could modify it script and use the new downloadable link?
