How to use trained model form checkpoints?

[proevgenii]

How can I make predictions with your model from checkpoints/USPTO50K_typed_checkpoint.pt ?
I've made all the steps before bash train.sh
P.S
I try to use them with script translate.sh from /OpenNMT-py/script/USPTO50K-aug-typed/translate.sh
By changing the path to weights, but it gives me an error:
Traceback (most recent call last): File "../../onmt/bin/translate.py", line 52, in <module> main() File "../../onmt/bin/translate.py", line 48, in main translate(opt) File "../../onmt/bin/translate.py", line 18, in translate translator = build_translator(opt, report_score=True) File "/raid/eprosvirin/anaconda3/envs/retroxpert/lib/python3.6/site-packages/onmt/translate/translator.py", line 28, in build_translator fields, model, model_opt = load_test_model(opt) File "/raid/eprosvirin/anaconda3/envs/retroxpert/lib/python3.6/site-packages/onmt/model_builder.py", line 97, in load_test_model model_opt = ArgumentParser.ckpt_model_opts(checkpoint['opt']) KeyError: 'opt'
