Working Scikeras Classifer model now broken with scikeras 0.13. AttributeError: 'Sequential' object has no attribute 'compiled'.

[CAW9]

Hello. I have used scikeras in my project for a while now. I was interested in upgrading to python 3.12 and scikeras 0.13, but it appears that using scikeras 0.13 breaks my project with the following error:

estimator.fit(X_train, y_train, **fit_params)
File "scikeras/wrappers.py", line 1501, in fit
super().fit(X=X, y=y, sample_weight=sample_weight, **kwargs)
File "scikeras/wrappers.py", line 770, in fit
self._fit(
File "scikeras/wrappers.py", line 928, in _fit
self._ensure_compiled_model()
File "scikeras/wrappers.py", line 439, in ensure_compiled_model
if not self.model.compiled:
^^^^^^^^^^^^^^^^^^^^
AttributeError: 'Sequential' object has no attribute 'compiled'

Thank you for any help you can provide. I did check doumentation to see if there were any changes I need to make to my code to keep up to date with 0.13, but it does not appear that any have been documented.

Would you mind providing a self contained reproducible example? Thanks!

Absolutely, I will work that up for you.

It looks like scikeras 0.13 is not compatible with keras 2, and scikeras 0.12 is not compatible with keras 3. Is this the case?

[adriangb]

Yes. I can’t maintain compatibility with two major versions unfortunately.

Thank you!

No further question.

I'm glad we figured it out and I'm sorry about not being able to support older major versions :(
