"""
Script to train the DTLN model in default settings. The folders for noisy and
clean files are expected to have the same number of files and the files to 
have the same name. The training procedure always saves the best weights of 
the model into the folder "./models_'runName'/". Also a log file of the 
training progress is written there. To change any parameters go to the 
"DTLN_model.py" file or use "modelTrainer.parameter = XY" in this file.
It is recommended to run the training on a GPU. The setup is optimized for the
DNS-Challenge data set. If you use a custom data set, just play around with
the parameters.

Please change the folder names before starting the training. 

Example call:
    $python run_training.py
