Error when running translate.py

Support
1

Hello,

I am getting an error when running the translate script on a trained model.

I run the following command:
python OpenNMT-py/translate.py -model opennmt_models/brnn_acc_40.74_ppl_37.57_e3.pt -src gu_codebase/data/src-val.txt -output opennmt_models/pred.txt -replace_unk -verbose

and receive the error message:
> xxx$ python OpenNMT-py/translate.py -model opennmt_models/brnn_acc_40.74_ppl_37.57_e3.pt -src gu_codebase/data/src-val.txt -output opennmt_models/pred.txt -replace_unk -verbose

  File "xxx/anaconda/lib/python3.5/site-packages/torch/serialization.py", line 469, in _load
    result = unpickler.load()
ImportError: No module named 'onmt.utils'

Any advice would be greatly appreciated.

Thanks,
Justin

You seem not to be on master.
can you try to update and run again ?

Hi Vince,

Thanks for your suggestion. I have updated and now get a new error:

Apologies, this seems to have been a silly error by me.

I had not run the requirements installs in the current environment and was using torchtext 0.2.3 instead of 0.3.0.

Thanks for your swift response though!
