Getting different model metrics when loading the same model

[stefisha]

As part of section 1, by the end when evaluating the best mode we decide to save model_2 with model_2.save("model_name.h5"). However when loading the same model, in this case model_name.h5, i get different (worse) results when checking the mean absolute error on the very same data. Is this normal behaviour, because in the course Daniel gets the same metrics with the same data?
I apoligize if someone already answered this question, because I did not find it. In case there is, just link it to me. Thanks
