 It is also recommended to set up a persistent disk from which to load checkpoints.
 Follow [this guide](https://cloud.google.com/tpu/docs/setup-persistent-disk#setting_up_a_tpu_vm_and_a_persistent_disk) to do so.

 * For the finetuning scripts, you can trim the length of the samples in your dataset.
   All the finetuning scripts expose a `--data.max_seq_length=...` argument. This might also be useful in cases where

-  shorter samples. For example, the median length of the samples in Alpaca is 110 tokens. Truncating the Alpaca dataset to 256 max tokens reduces the memory requirements of a Falcon 7B model from 23.52 GB to 15.73 GB. For more information about the dataset truncation, please see the *Truncating datasets* section in the [prepare_datasets.md](prepare_datasets.md) tutorial.

 Keep in mind that reducing the context length will affect the modelling performance on text sequences longer than the limit.
