Not sure about Accelerate, but if there is a wandb process running on your machine you can probably still just call wandb.run.name, without having to use the Accelerate experiment tracker object
@morgan@muellerzr to give you an idea of my usecase, being able to change the run name helps me when running multiple experiments. Basically, I read in several config json files and I associate those files with the run name. That way when I launch wandb I can track the config file and respective experiment.
