Federated Learning Miscellaneous

• Scripts required for setting up the system
• other miscellaneous directories used during developement

Setup the FL workspace

1. Install go and python

2. Install gRPC for go and python

3. Set directory strucuture in your $GOPATH/src as

   src/
   	fedota/
   		fl-misc
   

4. Setup

   cd fl-misc
   chmod +x fl_setup.sh
   ./fl_setup.sh
   

   Directory structure should then look like

   src/
   	fedota/
   		fedota-infra
   		fl-client
   		fl-coordinator
   		fl-misc
   		fl-proto
   		fl-selector
   		fl-webserver
   

5. [Optional] If you require proto definitions to be compiled

   cd fl-misc
   chmod +x fl_proto.sh
   ./fl_proto.sh
   

6. Create a common directory for fl-coordinator and fl-selector which stores the initial files (like checkpoint, model) and intermediate files for federated averaging. Make sure to change the config.yaml files in fl-coordinator and fl-selector accordingly.
   For example, the directory structure could be

   data/
   	initFiles/
   		fl_checkpoint
   		model.h5
   
   

   where data is the common directory which contains checkpoint(fl_checkpoint) and model(model.h5) files inside initFiles subfolder.

7. On the client side (or to simulate client locally), create a directory structure as mentioned in the problem description and place the dataset, config file and any other files in the specified locations.
   For example, a sample directory structure could be

   device1/
   	data/
   		train/
   		test/
   	config/
   		config.yaml
   

   where device1 is the root folder containing all the client data required for federated learning; data subfolder contains the dataset split into train and test; and config/config.yaml is the configuration file. Refer fl-client README to run fl-client.

Using pre-commit-hooks

• Install pre-commit using:

pip install pre-commit

• Install missing tools:

go get -u golang.org/x/tools/cmd/goimports
go get -u golang.org/x/tools/cmd/gorename
go get -u github.com/sqs/goreturns
go get -u github.com/mdempsky/gocode

• Run pre-commit hooks manually on all files:

pre-commit run --all-files

This will use the .pre-commit-config.yaml configuration

• Additionally if you want to run the hooks before every commit, use:

pre-commit install

This will add the required git hooks to be executed
