Prerequisites

Before running the code, you need to install the requirements, download the data, preprocess them and create the .env file.

The code uses ashleve's pytorch lightning hydra template https://github.com/ashleve/lightning-hydra-template. It is worth reading the template's README before trying to run the code.

Install requirements

Install the requirements in requirements.txt.

Download the data

Download the SeasFire dataset from zenodo. Note it is 44GB.

Unzip the dataset to a folder of your choice. We will refer to the unzipped zarr as DATASET_PATH in the rest of the README.

Create the coarsened dataset

See this notebook on how to create the coarsened dataset. This is necessary for the TeleViT experiments.

We will refer to the coarsened dataset as DATASET_PATH_GLOBAL in the rest of the README.

Create a .env file

Needs wandb account. If you don't want to use wandb, you need to dig into the code remove callbacks to wandblogger and use a different logger.

Create a .env file with the following variables:

WANDB_NAME_PREFIX="prefix_for_wandb_run_name"
WANDB_ENTITY="entity_for_wandb"
WANDB_PROJECT="project_for_wandb"
DATASET_PATH="`DATASET_PATH`"
DATASET_PATH_GLOBAL="`DATASET_PATH_GLOBAL`"

Running the experiments

To run the U-Net baseline:

bash scripts/unet_experiments.sh

To run the TeleViT experiments:

bash scripts/televit_experiments.sh

Notes on Resources needed

• RAM memory: The code uses about 100GB of RAM to load the dataset into memory. This makes the process slow to start (waiting to preprocess the dataset and load it). However, it allows for the flexibility to change the ML dataset between runs, apply any kind of preprocessing, forecasting in different time horizons, adding/removing variables.

• GPU memory: The code has been tested with NVIDIA GPUs with at least 24GB RAM. For smaller GPUs, you might need to play with the datamodule.batch_size
