Tensorflow C 内存泄漏 - valgrind

Tensorflow c++ memory leak - Valgrind

本文关键字：valgrind 泄漏 内存 Tensorflow      更新时间：2023-10-16

我正在执行简单的TensorFlow代码以创建图形def，如图所示

tensorflow::NewSession (options, &session)
ReadBinaryProto (tensorflow::Env::Default(), "/home/ashok/eclipseWorkspace/faceRecognition-x86_64/Data/models/optimized_facenet.pb", &graph_def));
session->Create (graph_def);

但是，当我运行valgrind时，如下所示

valgrind --leak-check=full --show-leak-kinds=all --vex-guest-max-insns=25 ./faceRecognition-x86_64 -r -i

我低于错误

当我做 session-> run（）

时，也会生成这些类型的错误

由于上述问题，运行程序所需的内存会随着时间的流逝而不断增加，并且由于在某个时间点之后内存不足而导致的应用程序崩溃

您是否关闭了会话？您还需要删除会话指针。

session->Close();
delete session;
