Implemented 99% my model and data processing. Now I fail since months by implementing a custom ConvRNN2D layer.

Since months I want to implement a VERY basic RNN layer for a project. Its kinda frustrating because 99% of the rest of the project is done. Its only the RNN layer and its a major point of the project.

So I beg you to just have a quick look to my stackoverflow post: https://stackoverflow.com/questions/71308645/warning-variables-were-used-in-a-lambda-layers-call-results-in-not-trainable

I would be VERY thankful if someone can give me the right hint to overcome this last obstacle! Thanks!
