This page explains how to resolve unresponsive processes that occur when you start a process with Hydra alongside W&B. If your process stops responding when you start it with Hydra, the likely cause is a multiprocessing conflict between Hydra and W&B. To fix this, change W&B’s multiprocessing protocol to "thread". This avoids the conflict so your process can start cleanly. You can do this in one of two ways:

Pass a settings parameter to wandb.init

Set a global environment variable
