QUESTION

OptKeras (Keras Optuna Wrapper) - use optkeras inside my own class, AttributeError: type object 'FrozenTrial' has no attribute '_field_types'

Asked 2020-Jul-06 at 23:29

I wrote a simple Keras code, in which I use CNN for fashion mnist dataset. Everything works great. I implemented my own class and classification is OK.

However, I wanted to use Optuna, as OptKeras (Optuna wrapper for Keras), you can see an example here: https://medium.com/@Minyus86/optkeras-112bcc34ec73.

However, something is wrong with my code. When I try to use optKeras inside my own class. Here's the code: (ordinary run method works, but optuna_run gives an error: AttributeError: type object 'FrozenTrial' has no attribute '_field_types'.

It seems that optkeras (version I got was 0.0.7) being not quite up-to-date with optuna library is the reason for the issue. I was able to make it work with optuna 1.5.0 by doing the following changes:

First, you'll need to monkey-patch get_default_trial like this before running your code:
