Unable to load vocab objects - _default_unk_index issue

See original GitHub issue

Exception: Error while loading vocabularies: Can't get attribute '_default_unk_index' on <module 'torchtext.vocab' from 'home/user/project/env37/lib/python3.7/site-packages/torchtext/vocab.py'>

I have trained an encoder-decoder model for translation. For the model I have pickled the vocabularies. Now, every time I launch the program, this problem occurs. So I have to reload and process the files, then recreate the objects, in order to use my model to translate from terminal or from a file.

To pickle the vocab objects I use the dill module. I load the vocabularies for the source and target language as follows: SRC_vocab = torch.load(os.path.join(path_to_exp, "src.pkl")), TRG_vocab = torch.load(os.path.join(path_to_exp, "trg.pkl"))

The problem occurs with python3.7, while with python3.6 it works fine.

Attached the dependencies file (python3.7: req_37.txt, python3.6: req_36.txt). req_36.txt req_37.txt
