Review comment:
> It looks like you're unconditionally removing and re-adding the node?
yep. That may be a small performance issue since it removes and re-add the
node even if the resources are not changed. However, the code of checking the
changes gets more complicated after the type is changed from `float64` to
`[]float64`. I prefer to update node unconditionally to keep code simpler.
