LSTM with variable sequences & return full sequences

How can I set up a keras model such that the final LSTM layer outputs a prediction for each time step while having variable sequence lengths as input?

I'd then like to provide labels for each of the timesteps after a dense layer with linear activation.

When I try to add a reshape or a dense layer to the LSTM model that is returning the full sequence and has a masking layer to take care of variable sequence lengths, it says:

The reshape and the dense layers do not support masking.

Would this be possible to do?

You can use the TimeDistributed layer wrapper for this. This applies the layer you want to each timestep. In your case, you could also just use TimeDistributedDense.
