gradient_accumulation_batch_size missing in trainer

[carbonz0]

I found
gradient_accumulation_batch_size exists in several scibert conf, such as
https://github.com/allenai/scibert/blob/8562a120e6788dcbadbe05ef7fd4463dee17ee59/allennlp_config/ner.json
but allennlp trainer doesn't have this param,
https://github.com/allenai/allennlp/blob/master/allennlp/training/trainer.py

Yes, AllenNLP doesn't support gradient accumulation. We have it implemented in our fork of allennlp (check requirements: https://github.com/allenai/scibert/blob/master/requirements.txt)

Hi, The installation command in the readme returned the following "allennlp version not found error". Can I ask what is the right way to install the tool and reproduce the results?

Thank you very much!
