Check whether 'optimal_lgbm_param_values.txt' exists in the cloud #44
Description
If a text file with optimized hyperparameter values (these will come from the grid search) is present, we want to use those values. Otherwise, we want to use the default hyperparameter values as they are specified in the script.
Currently, only when running locally I have managed to check the existence of 'optimal_lgbm_param_values.txt'. This should also be implemented for running the code in the cloud.
