Description:
 def is_scalar(value):
 """Test if the given value is a scalar. This function also works with memory mapped array values, in contrast to the numpy is_scalar method. Args: value: the value to test for being a scalar value Returns: boolean: if the given value is a scalar or not """

    return np.isscalar(value) or (isinstance(value, np.ndarray) and (len(np.squeeze(value).shape) == 0))
