Why does `examples/translation/t5` test on newstest2013 rather than newstest2014?
# Details
<!-- Description of your issue -->
The example in examples/translation/t5 uses `newstest2013`, but authors report against `newstest2014` (presumably newstest2014.full):
> Since this is our final set of experiments, we report results on the test set rather than
the validation set. For CNN/Daily Mail, we use the standard test set distributed with the dataset.
For the WMT tasks, this corresponds to using newstest2014 for English-German

Is this intentional?
Hey @tholiao,

Thanks for the catch! You're right it should be the newstest2014! Do you want to open a PR to change it? Or I can do it as well<|||||>No worries, I'll submit a PR.<|||||>@patrickvonplaten, would you mind running evaluate_wmt.py on this branch and computing sacreBLEU via command line? (`cat newstest2014_de_translations.txt | sacrebleu -t wmt14 -l en-de --tokenize intl`)<|||||>Thanks a lot for the PR! I will running the script once the PR is merged :-)
