Create a Trainer based on the given parameters

Specified by:

create in interface TrainerContext

Parameters:

threadId - the thread id to use for this worker

model - the model to start the trainer with

rootDevice - the root device id

useMDS - whether to use MultiDataSet or DataSet or not

wrapper - the wrapper instance to use with this trainer (this reference is needed for coordination with the ParallelWrapper 's TrainingListener

Returns:

the created training instance
