tensorflow c++进行在线预估卡死hang住
2024-04-23 18:52:13
一、 tensorflow 离线训练导出格式
- Tensorflow 离线训练的结果可以使用某种格式导出，如 SessionBundle、SavedModel、FreezedGraph，本次在使用SavedModel方式保持模型，进行在线预估。
二、在线预估代码
- 模型加载逻辑
bool TensorModel::LoadModel(const std::string& model_path) {tensorflow::SessionOptions session_options;tensorflow::RunOptions run_options;std::unordered_set<std::string> saved_model_tags;saved_model_tags.insert(tensorflow::kSavedModelTagServe);tensorflow::Status status = tensorflow::LoadSavedModel(session_options, run_options, model_path,saved_model_tags, &model_bundle_);if (!status.ok()) { LOG(ERROR) << "LoadSavedModel Failed: " << status.ToString();return false;}return true;
}
- 在线预估逻辑，发现在预估的时候此处出现了hang住的请求，没有反应
tensorflow::Status status = model_bundle_.session->Run(tf_feature.input, {out_tname}, {}, &outputs);
- 具体堆栈

三、问题总结
由于hang住没有任何信息，尝试看堆栈，看源码，打日志都没有办法定位问题，感觉很无助，最开始一直怀疑是input的问题，于是尝试使用tf_serving进行加载模型预估也存在同样的问题。
最终定位还是离线在使用savedmodle模型进行保存模型方式不对，保存的网络图结构不对，没有保存正确的output图节点，导致预估找不到结果。
