Any plans to support keras3? #1119

Open Krovatkin opened 4 months ago

Krovatkin commented 4 months ago

System information

Motivation Keras3 is the latest version and it supports multiple backends including Pytorch.

Describe the feature

Supporting keras3 when using different tfmot features including quanitization. Are there any plans to provide support for keras3? and what needs to be done to support it?

Currently running 

import keras
import tensorflow_model_optimization as tfmot

fails with

Hello @Krovatkin, thanks for the issue. Could you provide specific version of Keras 3?

Krovatkin commented 3 months ago

@tucan9389 yes, I'm so terribly sorry for missing yr reply!

We are on 

keras=3.0.1
tensorflow=2.12.0

and python=3.10

tucan9389 commented 3 months ago

@Krovatkin

Thanks for the information.

Unfortunately, we don't have a plan to support this library for Keras3 at the moment.

However we're welcome to the contribution. Please contribute if you could fix this error!
