STensor::AutodiffRenewReturn syten::STensorImpl::STensor::get_and_renew_autodiff

(

)

Returns a struct AutodiffRenewReturn as if by executing.

auto [old_id, old_node] = get_autodiff();
auto old_number = old_node->get_output_number(old_id);
auto new_id = new_autodiff_id();
AutodiffRenewReturn r;
r.old_id = old_id;
r.old_node = old_node;
r.old_number = old_number;
r.new_id = new_id;
