CPU_ONLY构建：编译函数 Forward() 会给出错误"undefined reference..."

CPU_ONLY build: compiling the function Forward() gives error "undefined reference..."

本文关键字：出错错误 undefined reference 构建 ONLY 编译 Forward 函数 CPU 更新时间：2023-10-16

我是Caffe库的初学者。我只是在这个教程示例中编译和测试代码：https://github.com/DeepLearningStudy/caffe/blob/master/examples/ex4_layer/main.cpp。我有一个CPU_ONLY版本，所以编译会给出对"void caffe:：caffe_gpu_dot(int，double const*，double const*，double*)"的错误未定义引用。通过调用函数Forward()发出。为了完成编译，我修改了argmax层代码，并将forward_cpu()作为公共函数成员。

尽管有这样一句话：Caffe：：设置模式(Caffe:：CPU)似乎正向函数调用gpu方法。

这是我的CMakeLists.txt：cmake_minimum_required(VERSION 2.8.8)

有人知道为什么或者有更好的解决方案吗？
问候

在定义行中添加以下内容：

set(Caffe_DEFINITIONS "-DUSE_OPENCV;-DUSE_LMDB;-DUSE_LEVELDB;-DCPU_ONLY=1")

CPU_ONLY=1应正确注释掉所有GPU代码。
