Modes

Grid currently has two modes.

--tree -- experimental

Tree is the federated learning mode. The long term goal is to have node workers store data locally, and train public models to make them better.

--compute

Compute mode lets users offer compute to train models. Data scientists can easily publish models from a jupyter notebook and train them remotely. Grid also offers easy utilities to try n number of configurations concurrently.

Launching a Worker

Start the IPFS Peer-to-Peer Filesystem

Grid worker daemon requires an IPFS daemon to be running with pubsub support turned on.

./bin/start_ipfs

Make sure you have installed all dependencies

pip3 install -r requirements.txt

python3 setup.py install

You can then run the worker daemon. If you want to run in compute mode run

./bin/start_worker --compute

and if you want to run in tree mode, run

./bin/start_worker --tree

Finally, to run the notebooks - in a different tab start Jupyter by running:

jupyter notebook

navigate to notebooks/pubsub/ and open Keras Grid Client and Worker.ipynb and follow along in that notebook.

Troubleshooting

Connect Error

If you see this connect error ERROR: could not connect to IPFS. Is your daemon running with pubsub support at 127.0.0.1 on port 5001 make sure you run the following command:

ipfs daemon --enable-pubsub-experiment

Trouble Running Experiment

If you have any troubles running an experiment such as the other peers not learning about your jobs make sure you're connected to the peer. You can check if you're connected to the peer by running:

ipfs pubsub peers | grep <ipfs address>

And then to connect to the peer if you're not connected:

ipfs swarm connect <ipfs_address>
