What does 'INFO:tensorflow:Oracle triggered exit' mean with keras tuner?
I had the same question and didn't find what I was looking for.
If the tuner have finished at trial, that is lower then your max_trial parameter, the most probable reason is that the tuner have already tried all the combinations possible for the field of hyperparameters that you set before.
Example: I have 2 parameters for tuner to try, fist can optain 8 values, second 18. If you multiply these two it gives you 144 combinations and that is exactly the number of trials that the tuner stopped at.
When I run Keras Tuner search, the code runs for some epochs and then says:
'INFO:tensorflow:Oracle triggered exit'.
What does this mean? I am still able to extract best hyperparameters. Is it due to early stopping? I have tried both randomsearch and hyperband.
