Why the answer is incorrect even if i am using correct answer in the quiz course 4 week 3?

@DHANOLA, it’s sort of hard to tell, but in that note showing how to use shape, there’s a space between the comma and dim

Same question. I also did use space and still was flagged wrong. See below:

tf.keras.backend.random_normal(shape = (batch, dim))

Hi @eatsMelon,
The quiz is being very specific about what it expects for an answer. It’s expecting you to use shape=(batch, dim) exactly like it is in the note: with no spaces before or after the =, and with a space after the ,

It would be good if the quiz were more lenient about spaces. I’ll put in a request to the course staff.
