Sweep

Utilites for hyperparameter sweeps, using Weights and Biases. These instructions are a minimial subset of these docs.

To begin a sweep follow these steps:

1. Make sure wandb is installed:

   pip install wandb

2. Login to wandb:

   wandb login

3. Initialize wandb (optional)

   wandb init

4. When asked to choose a project make sure you select covasim. If you don't see a project with this name, instead select Create New and name your project covasim.

5. From the root of this repo, initialize a sweep.

   # Choose the yaml file that corresponds to the search strategy.
   wandb sweep sweep/sweep-random.yaml

   This command will print out a sweep ID. Copy that to use in the next step!

6. Launch agent(s)

   wandb agent your-sweep-id

   From the docs:

   You can run wandb agent on multiple machines or in multiple processes on the same machine, and each agent will poll the central W&B Sweep server for the next set of hyperparameters to run.
