Thank you @Giangblackk. The variable x you created could not be visualized as it is empty. Its first dimension is 0, it has no element. With x =np.zeros((1, 10, 20)) it works fine.
@ccordoba12 should we add a check to not support the empty arrays?

[ccordoba12]

@Prikers, we do support empty arrays, so we should catch this error and show an empty array editor instance.
