is it possible that I implement this method using Keras?

[Cocoalate]

I cannot use pytorch to do my research for some reason., so I'm trying to "translate" the code to keras form. Now I've completed the dataloader (data generator in Keras) part, but I'm stuck with putting both balance sample data and reverse sample data in the backbone model to get 2 features. How can I use Keras "fit" or "compile" to process both forms of data? Or is it possible to use the method using Keras?

same issue, have you solved the problem?
