I was running out of date code.

Hi @schmmd. Could you please help me? I cannot train the model too. I have the latest version of the code, but I am using the pretrained model which is available on this site:

ner-model-2018.12.18.tar.gz

I get the same error: Traceback (most recent call last): File ".../Research.py", line 372, in validation_iterator=None) File "...\venv\lib\site-packages\allennlp\training\trainer.py", line 687, in from_params optimizer = Optimizer.from_params(parameters, params.pop("optimizer")) File "...\venv\lib\site-packages\allennlp\common\params.py", line 248, in pop raise ConfigurationError("key \"{}\" is required at location \"{}\"".format(key, self.history)) allennlp.common.checks.ConfigurationError: 'key "optimizer" is required at location ""'

I used the config which is in the ner-model-2018.12.18.tar.gz archive.

Also I used the config which is available here: https://github.com/allenai/allennlp/blob/master/training_config/ner.jsonnet

But I still get the error. Could you please tell me how have you fixed the problem? I can't train the model

@lyriccoder can you open a new issue with a full reproduction? It would be good to know the exact command you are running to retrain a model, as well as the version of AllenNLP you are using. If you're getting an error, please include the full stacktrace.
