Tools like Keras Tuner or Hyperas require to modify the code. For large applications, this can be quite cumbersome, especially w.r.t. parameters that are not part of the model itself (e.g. settings for data preprocessing). Moreover, it complicates maintenance of the code base (development vs. production). For this reason, I’m looking for a minimally invasive hyperparameter tuner that works at the level of executables / scripts and passes parameters via command line arguments. Any hints or ideas? Thanks a lot!
