no member named ‘getUnconnectedOutLayersNames’

main.cpp，make时报错：
main.cpp:232:36: error: ‘class cv::dnn::experimental_dnn_34_v7::Net’ has no member named ‘getUnconnectedOutLayersNames’; did you mean ‘getUnconnectedOutLayers’?
this->net.forward(outs, this->net.getUnconnectedOutLayersNames());
我用的opencv3.4，请问是opencv版本的问题吗？

opencv版本升级到最新的4.5

已放弃 (核心已转储)
必须使用4.5以上的版本吗？这个core是因为版本不对造成的吗
