Dbow2函数调用问题

[wenbin-hhhhh]

error: ‘openvslam::data::bow_vocabulary {aka class DBoW2::TemplatedVocabulary<cv::Mat, DBoW2::FORB>}’ has no member named ‘loadFromBinaryFile’
bow_vocab_->loadFromBinaryFile(vocab_file_path);
调用DBoW2库时报错，请问这是版本问题还是？

You need different DBoW2 version: https://github.com/shinsumicco/DBoW2
