tensorflow TypeError: cannot unpack non-iterable float object

Question

I am using tensorflow V2.2 and run into TyepError when I do model.evaluate. Can someone advise what the issues may be? A screenshot of the execution and error message is shown below.

Answer 1

you need to define a metric when you compile the model model.compile('adam', 'binary_crossentropy', metrics='accuracy')

in this way during evaluation, loss and accuracy are returned
