To use experiment trackers with `accelerate`, simply pass the desired tracker to the `log_with` parameter
when building the `Accelerator` object. Then initialize the tracker(s) by running `Accelerator.init_trackers()`
passing in any configurations they may need. Afterwards call `Accelerator.log` to log a particular value to your tracker.
At the end of training call `accelerator.end_training()` to call any finalization functions a tracking library
may need automatically.
