Week 3- Cannot convert 0.5 to EagerTensor of dtype int64

I am receiving this error while every function and inputs seems right to me!

The error message indicates that your box_classes_scores is int64, which is not correct.
I’m afraid that you mixed up box_classes and box_class_scores. Please revisit your code to calculate “box_class_scores”. “class” can be “int”, but “class_scores” should be “float”.
