错误：无法在boost中调用impl_pointer的成员函数impl（）

Question

我正在尝试为对象检测构建一个名为SSD的Caffe版本

我检查了代码，我得到错误cannot call member function ‘boost::multi_index::detail::sequenced_index_node<Super>::impl_pointer boost::multi_index::detail::sequenced_index_node<Super>::impl()似乎与boost库有关，我已经安装了boost作为依赖：

                   ~~~~^~

有什么想法如何纠正？

Answer 1

显然不是最好的解决方案，但我通过在Makefile.config中启用CPU_ONLY模式解决了这个问题
