Keras Bidirectional “RuntimeError: You must compile your model before using it.” after compilation completed

Question

I\'m trying to create a small Bidirectional recurrent NN. The model itself compiles without error, but when trying to fit the model I get the error stating I should compile

Answer 1

Found it,
When using Bidirectional, it should be treated as a layer, shifting the input_shape to be contained in Bidirectional() instead of in the GRU() object solved the problem

so

bidirectional_recurrent.add(Bidirectional(GRU(32, input_shape=(int(lookback/steps),
                            data_scaled.shape[-1]))))

becomes

bidirectional_recurrent.add(Bidirectional(GRU(32), input_shape=(int(lookback/steps),
                            data_scaled.shape[-1])))
