Add data flexibility to decoder trainer ( #165 )
...
* Added the ability to train decoder with text embeddings
* Added the ability to train using on the fly generated embeddings with clip
* Clip now generates embeddings for whatever is not precomputed

Distributed Training of the Decoder ( #121 )
...
* 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
