Storing additional list values in trial.json?

[Anselmoo]

Is it possible to store a list during the run? oracle.update_trial unfortunately only supports float or str.

   self.oracle.update_trial(
            trial.trial_id,
            {
                "objective_1":  float or str,
                "objective_2":  float or str
                "objective_3":  float or str      
            },

preferred:

   self.oracle.update_trial(
            trial.trial_id,
            {
                "objective_1":  [float, float, str]
            },

Would it be very difficult to extend keras_tuner by a new function, self.oracle.update_meta, due to the message protocol?

thx

I've added this.

It is only meant to work with new Keras though (and run multibackend wo crashing hopefully.), no backwards compatibility.

There are "example outputs" that you can check the format of. https://github.com/ghsanti/keras-tuner

(PS: The general idea is: save all the details to trial.json, but provide use with optional summaries etc.)
