Parameters
----------
params : ``Params``
A parameter object specifying an AllenNLP Experiment.
serialization_dir : ``str``
The directory in which to save results and logs.

List of debate turns (e.g. aa, ar, rr, Ar) => capitalization implies search agent
file_friendly_logging : ``bool``, optional (default=False)
If ``True``, we add newlines to tqdm output, even on an interactive terminal, and we slow

recover : ``bool``, optional (default=False)
If ``True``, we will try to recover a training run from an existing serialization

force : ``bool``, optional (default=False)
If ``True``, we will overwrite the serialization directory if it already exists.
judge_filename : ``str``, optional (default=None)
Path to judge config or pre-trained judge model. If config, judge trained during debate. Necessary parameter
if running in debate mode.
update_judge : ``bool``, optional (default=False)
Boolean whether or not to update Judge model during debate training.
eval_mode : ``bool``, optional (default=False)
Boolean whether or not to run in eval-only mode, on test data. Does not update/train any of the models.
reward_method : ``str``, optional (default=False)
Choice of reward function (RL) or loss function (Supervised Learning) for training debate agents
detach_value_head : ``bool``, optional (default=False)
Boolean whether or not to detatch value function gradient updates from the policy network. This prevents
value function gradients from affecting policy network parameters.
breakpoint_level : ``int`` optional (default=0)
Debugging option to set breakpoint sensitivity (0 - no breakpoints).
id_to_search_filename : ``str`` optional (default=None)
Path to file with search predictions for each agent - necessary for supervised training
accumulation_steps : ``int`` (default=1)
Number of gradient steps to accumulate over before performing an update. Poor-man's batching for instances where
number of examples per batch is small (limited GPU memory)
multi_gpu : ``bool`` (default=False)
Boolean whether or not to run models/training in model parallel mode. Requires specifying GPU allocations for
trainer, judge, and debaters in the training config file (see training_config/bidaf.race.size=0.5.gpu=2.jsonnet
for example usage).
