Question

您好，我在安装Caffe时遇到问题。我按照说明https://github.com/BVLC/caffe/wiki/Ubuntu-16.04-Installation-Guide（针对CPU版本）进行了所有操作在命令中输入以下内容：

CXX src/caffe/util/io.cpp

输出中也有很多文本，但是由于字符数限制，我无法上传

Makefile:591: recipe for target '.build_release/src/caffe/util/io.o' failed
make: *** [.build_release/src/caffe/util/io.o] Error 1

有人可以帮助我解决这个问题吗？

OS：Ubuntu 16.04 cmake版本3.5.1 CUDA版本：10.0.130

Answer 1

问题出在OpenCV的第4版中。 Caffe无法使用它。当我安装第三个版本时，一切正常。

Caffe构建失败：Makefile：591：目标'.build_release / src / caffe / util / io.o'的配方失败
