I’m getting this error.

TypeError: call() got an unexpected keyword argument ‘outputs’

I guess that error is in calling:

               inference_model =  model(inputs=[x, a, c], outputs=output)

The HINT says: Hint : the inputs to the model are the initial inputs and states.

But I don’t understand what are the correct initial inputs.

Can you help me ?

Hello @Dalton_Lintz,

I think the error is due to typo. We use tf.keras.models.Model (or in short Model as defined in the assignment) to build a model object, but you used model (defined earlier in the globa scope) which is itself a model object to do the building work, so it failed.

Cheers,
Raymond
PS: I also spotted another thing in that line.

You are correct Raymond, it’s a typo. What I’m trying is

model(inputs=[x, a, c], outputs=out)

But the error message is the same.

I get it !!! It’s working now . Thank you Raymond

That’s great, @Dalton_Lintz!
