Example: ```Py a = sc.array(dims=['x'], values=[1, 2, 3, 4, 5], unit=None) a.mean() ``` raises `UnitError: Cannot multiply with operand of unit 'None'.`. I expected to get `sc.scalar(3., unit=None)`.
Example:
raises
UnitError: Cannot multiply with operand of unit 'None'..I expected to get
sc.scalar(3., unit=None).
