**Python version:**python3.6
Code to reproduce the issue
here is my train function:

Here is my model:

thanks a lot~

when I drop arguments:callbacks in model.fit(),it raises another error:

it really makes me confused...

Hi @johnwang416 , sorry for really late response.

Just want to check if this still bugs you before picking up this again.
