I’m using the Keras Trainer pattern as illustrated [here](https://keras.io/examples/keras_recipes/trainer_pattern/). The issue when using this pattern is that when you use Tensorboard only the top level weights are being recorded.

The reason for this is that `Tensorboard` is recording the weights for the all the layers in `self.model.layers`. But this equal to `[<Sequential name=sequential, built=True>]` and the weghts for that Sequential object is

I tried several things:

1. Passing a CallBackList to the Tensorflow Trainer when calling fit passing model\_a instead of trainer\_a, but this fails because model\_a has no optimizer
2. I tried to overwrite the `layers` method in thr Trainer object to have `recursive=True` but the weights were still not showing in TensorBoard suggesting that something else is going on

I’m open to any suggestions here. I also opened an issue on the keras repo: [Tensorboard not working with Trainer Pattern · Issue #20809 · keras-team/keras · GitHub](https://github.com/keras-team/keras/issues/20809)
