Hi @FViloria ,
Please note that we have a Sequential Model example and a Functional API example. In both cases, the way to pass from one layer to another is a bit different. Please make sure not to use a syntax from one to another.
Keep learning!

Did you post the entire error message? It seems there should be more information there.
A screen capture image is preferred.

In your “Z1 = …” code:

  • “filters” should be an integer. Yours is a tuple, that’s why the error message about “tuple and int”.
    The kernel size can be either a tuple or a list.

  • Also check whether you have the correct filters and kernel size values.

Thank you Tom, corrected, but the output is wrong

The values I’ve flagged here are incorrect:

Check the parameters you are passing to those layers.

Thank you Tom, i fixed it, all test passed
