Week 1 grading

my code works, the model is learning, but i get this grading error on submission

Any ideas, why this happens?

Hi @Manuel_Geusen,

You are using keras.src somewhere in the notebook which the autograder has no idea about (it is not part of the autograder environment).

Please make sure to replace keras.src, wherever you are using it in the notebook, with what is required to be used.
