Sorry, your submission was incorrect. Please try again. type numpy.ndarray doesn't define __round__ method

what does error suppose to mean? I have submitted the assignment nearly about 10 times if I returned a float value the grader says

Your result did not return as np.ndarray

Hi @husseinmleng,
I cannot tell for sure without seeing your code, but it seems like your code doesn’t give back an array, as it should be.

Here is my code

The model is expecting a float as input but you passed a list.

when I passed a float value this error arises

AttributeError: 'float' object has no attribute 'shape'

Check what the
you wrote at the end of your function returns (that seems to be the problem) and then modify it.
