支持增量导出有问题

/tmp/x-deeplearning/xdl/ps-plus/ps-plus/main/main.cc:117] ERROR ON Server Init: ErrorCode [3]: StreamingModelManager [hdfs] Not found

我看里面的代码
virtual Status WriteDenseModel(const std::vector& val, const std::string& stream_version) = 0;
virtual Status WriteSparseModel(const std::vector& val, const std::string& stream_version, const int& server_id) = 0;
virtual Status WriteHashModel(const std::vector& val, const std::string& stream_version, const int& server_id) = 0;
这三个函数都没有实现哦。是纯虚的。是不是缺少文件。。

Start at main/main.cc:117 and trace the Server Init failure for StreamingModelManager [hdfs] Not found. Then inspect the WriteDenseModel, WriteSparseModel, and WriteHashModel pure virtual declarations to determine where their implementations are expected. Done means identifying and resolving the missing incremental-export path, with a reproducible initialization check.
