I’ve been trying to figure it out for about a week now but I keep getting ‘Data cardinality is ambiguous’. I’m creating a sequential model for each multivariate sequence, then concating the .output from each of those models as the input to a Keras model. I’m also feeding the inputs in as a list of each .input from each model.
Even when I make the last layer of each sequence’s model a dense layer with the same amount of units, the cardinality error still complain’s about concating different sequence lengths.
Any ideas or working code appreciated
