Overhauled the tracker system ( #172 )
...
* Overhauled the tracker system
Separated the logging and saving capabilities
Changed creation to be consistent and initializing behavior to be defined by a class initializer instead of in the training script
Added class separation between different types of loaders and savers to make the system more verbose
* Changed the saver system to only save the checkpoint once
* Added better error handling for saving checkpoints
* Fixed an error where wandb would error when passed arbitrary kwargs
* Fixed variable naming issues for improved saver
Added more logging during long pauses
* Fixed which methods need to be dummy to immediatly return
Added the ability to set whether you find unused parameters
* Added more logging for when a wandb loader fails

* Converted decoder trainer to use accelerate
* Fixed issue where metric evaluation would hang on distributed mode
* Implemented functional saving
Loading still fails due to some issue with the optimizer
* Fixed issue with loading decoders
* Fixed issue with tracker config
* Fixed issue with amp
Updated logging to be more logical
* Saving checkpoint now saves position in training as well
Fixed an issue with running out of gpu space due to loading weights into the gpu twice
* Fixed ema for distributed training
* Fixed isue where get_pkg_version was reintroduced
* Changed decoder trainer to upload config as a file
Fixed issue where loading best would error
