      Arguments
      ---------
      hparam_file : path
          Path of the yaml file containing the hyperparameters.

          Path of the script file (.py) containing the training recipe.

      -------

          This function returns False if some mismatch is detected and True otherwise.
          An error is raised to inform about which variable has been declared but
