Higher values may yield stronger language models at the cost of slower and more memory-intensive training
In addition, if memory usage is an issue, especially when training on a single GPU, reducing `--train_batch_size` from
the default 32 to a lower number (4-16) can be helpful.
the default 32 to a lower number (4-16) can be helpful. There is also a `--reduce_memory` option for both the
`pregenerate_training_data.py` and `finetune_on_pregenerated.py` scripts that spills data to disc in shelf objects
or numpy memmaps rather than retaining it in memory, which hugely reduces memory usage with little performance impact.
