Running the Federation

On the Aggregator

  1. To start the aggregator, run the following script from the bin directory. Note that we will need to pass in the shared single collaborator cert common name in order to specify that we are running in single cert test mode (this mode should only be used for testing purposes).

$ ../venv/bin/python3 ./run_aggregator_from_flplan.py -p keras_cnn_mnist_2.yaml -scn test --c cols_2.yaml

At this point, the aggregator is running and waiting for the collaborators to connect. When all of the collaborators connect, the aggregator starts training. When the last round of training is complete, the aggregator stores the final weights in the protobuf file that was specified in the YAML file (in this case keras_cnn_mnist_latest.pbuf).

On each Collaborator [col_number = ‘0’ and ‘1’]:

  1. From the bin directory, run the collaborator using the following script, passing in the shared single collaborator cert common name in order to specify that we are running in single cert test mode (this mode should only be used for testing purposes).

$ ../venv/bin/python3 ./run_collaborator_from_flplan.py -p keras_cnn_mnist_2.yaml -col col_<col_number> -scn test
