Dependencies

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Getting Started:

Test model predictions on the evaluation set with Jupyter Notebook provided in elects.ipynb

Run Training Loop

Monitor training visally (optional)

start visdom server for visual training progress

❯ visdom
Checking for scripts.
It's Alive!
INFO:root:Application Started
You can navigate to http://localhost:8097

and navigate to http://localhost:8097/ in the browser of your choice.

Start training loop

To start the training loop run

❯ python train.py
Setting up a new session...
epoch 100: trainloss 1.70, testloss 1.97, accuracy 0.87, earliness 0.48. classification loss 7.43, earliness reward 3.48: 100%|███| 100/100 [06:34<00:00,  3.95s/it]

The BavarianCrops dataset is automatically downloaded. Additional options (e.g., --alpha, --epsilon, --batchsize) are available with python train.py --help.

Docker

It is also possible to install dependencies in a docker environment

docker build -t elects .

and run the training script

docker run elects python train.py

python train.py --dataroot /data/sustainbench --dataset ghana python train.py --dataroot /data/sustainbench --dataset southsudan

--dataroot /data/sustainbench --dataset southsudan --epochs 500
