TranslationDataset is now deprecated in torchtext

[imkzh]

Since TranslationDataset is deprecated (see Issue 985), could you please kindly update the relevant code to work with newer version of torchtext?

> python preprocess.py -lang_src de -lang_trg en -share_vocab -save_data m30k_deen_shr.pkl

Traceback (most recent call last):
    File "preprocess.py", line 15, in <module>
    from torchtext.datasets import TranslationDataset
ImportError: cannot import name 'TranslationDataset' from 'torchtext.datasets' 

The current version number of torchtext is 0.12.0.

Also: what version of torchtext may current code in this repository work with?

[yijin-yf]

Up to now, the latest version of torchtext is 0.11.2, which discarded the TranslationDataset. If you want to use TranslationDataset, please install torchtext==0.3.1.

[R-N]

You can use 0.6.0, but the hardcoded dataset link in 0.3.1 - 0.6.0 is dead.
I patched it up a bit here https://github.com/R-N/torchtext/tree/0.6.1
