Use pipenv to set up your environment.
Write the EMNIST dataset to disk using write_emnist_dataset.py.
Customize NUM_ROUNDS and NUM_CLIENTS in experiment.py and run it.
For executing a single step (i.e. a particular client training on local data and submitting a transaction), run step.py f0000_14 10, where f0000_14 is the client id and 10 corresponds to tangle_data/tangle_10.json.
To view tangles in a web browser, run python -m http.server in the repository root and open http://localhost:8000/viewer/. You may need to slide the slider to the left to see something.
