logits (mx.array): The predicted logits.
targets (mx.array): The target values.
axis (int, optional): The axis over which to compute softmax. Defaults to -1.
reduction (str, optional): Specifies the reduction to apply to the output: 'none' | 'mean' | 'sum'.
'none': no reduction will be applied.
'mean': the sum of the output will be divided by the number of elements in the output.
'sum': the output will be summed.
Defaults to 'none'.
