    This script trains a LAFTR model. For the full evaluation used in the paper (first train LAFTR then evaluate on naive classifier) see `src/run_laftr.py`.

    Instructions: 
    1) Run from repo root
    2) First arg is base config file
    3) Optionally override individual params with -o then comma-separated (no spaces) list of args, e.g., -o exp_name=foo,data.seed=0,model.fair_coeff=2.0 
       (the overrides must come before the named templates in steps 4--5)
    4) Set templates by name, e.g., --data adult 
    5) Required templates are --data and --dirs
    
    e.g.,
    >>> python src/laftr.py conf/laftr/config.json -o train.n_epochs=10,model.fair_coeff=2. --data adult --dirs local

    This command trains LAFTR on the Adult dataset for ten epochs with batch size 32.
    Model and optimization parameters are specified by the config file conf/classification/config.json
    Dataset specifications are read from conf/templates/data/adult.json
    Directory specifications are read from conf/templates/dirs/local.json
    Finally, two hyperparameters are overridden by the last command.
    By using the -o flag we train for 10 epochs with fairness regulariztion coeff 2. instead of the default values from the config.json.
