# RotoBART

## Running the script

### Script arguemnts

Available model config arguments from script:
```
encoder_layers
encoder_ffn_dim
decoder_layers
decoder_ffn_dim
d_model
vocab_size
max_position_embeddings
encoder_layerdrop
decoder_layerdrop
```

Training Arguments:

`testing` : only uses 1 batch, for testing the script

`adafactor`: will enable adafactor, removing the command will revert to Adam

`grad_accum`: what value for gradient accumulation to use, default is 4

`use_bf16`: convert the model to bf16

`colab_tpu`: if running on a colab TPU

`use_wandb`: log using Weights & Biases (via Tensorboard)

`save_strategy`: whether or not to save model checkpoints based on steps or epoch
