Despite correct answer, i am unable to submit the answer

Topic is Numpy - Broadcasting in NumPy Arrays.

Code is as below:
import numpy as np
X_board = np.ones((3,3))
print(X_board)

Y_board = np.arange(3)
print(Y_board)

Z_board = X_board + Y_board
print(Z_board)

when i submit, i get the below error:
" X_broad should be a Numpy array"

Hi,

Try Restarting the Kernel and run your code again.

Thanks!
