I have a problem with the subscription of the week’s assignment number 2. I always get this error while before i did not
Cell #16. Can’t compile the student’s code. Error: ValueError(‘Please provide to Input either a shape or a tensor argument. Note that shape does not include the batch dimension.’)

Which week and assignment are you referring to?

the problem has actually vanished. thank you
But still i receive an error due to the accuracy function that i do not understand:

and in the grading window: Unexpected error occurred during variable check. We expected variable metrics to be of type <class ‘str’>. Please check that this variable is initialized and is of the right type.
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.
This dependency may be the cause of the errors.

I think that i have used the right one but the corrector cannot identify it
Could you please help me?

How did you assign the metrics variable?
“accuracy” is not a function. It’s just a text string inside square brackets.

I used the kera function

That’s the problem. It isn’t a layer.
It’s just a text string inside square brackets.

ok thank you but still, I don’t get how to fix it. Do I need to assign the string outside the layer? Thank you in advance

I’ve already said how to fix it twice. Read my posts again.
