I had build the hybrid CNN and LSTM model using Tensorflow 2.17 version. I want to add the backpropagating tuning to the LSTM to modify the weight of the LSTM layers. I try to find a way to access the weight to do calculation and update the weight during training for the LSTM . I had do some research where they build the LSTM manually instead apply tensorflow API. I just curious if there is a way that I could access the weight , then apply derivative and finally update while training.
