糟心的caffe+ matlab编译路程

时间：2019-06-12 21:22:31   收藏：0   阅读：134

配置：Ubuntu16.04+MatlabR2016b+cuda8.0+cudnn5.1+caffe

配置caffe真的不是很容易，特别是对初次接触Linux的同学，各种报错(ノ_；＼( ｀ロ′)，搞了好几天才解决

caffe安装可能出现的问题

可能会出现的问题

问题1."libcudart.so.8.0 cannot open shared object file: No such file or directory"
解决方法：
解决办法是将一些文件复制到/usr/local/lib文件夹下：
注意自己CUDA的版本号！

sudo cp /usr/local/cuda-8.0/lib64/libcudart.so.8.0 /usr/local/lib/libcudart.so.8.0 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcublas.so.8.0 /usr/local/lib/libcublas.so.8.0 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcurand.so.8.0 /usr/local/lib/libcurand.so.8.0 && sudo ldconfig

问题2."libcudnn.so.5 cannot open shared object file: No such file or directory"
解决方法：
解决办法是将一些文件复制到/usr/local/lib文件夹下
注意自己CUDA的版本号！

sudo cp /usr/local/cuda-8.0/lib64/libcudnn.so /usr/local/lib/libcudnn.so && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcudnn.so.5 /usr/local/lib/libcudnn.so.5 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcudnn.so.5.1.5 /usr/local/lib/libcudnn.so.5.1.5 && sudo ldconfig

问题3."OSError: libcudnn.so.7.0: cannot open shared object file: No such file or directory错误"
解决方法：

#因为cuda的路径可能设置错了

sudo ldconfig /usr/local/cuda/lib64

问题4.linux下Matcaffe调用及库链接问题的解决（mattest不通过）
解决方法：

编译make matcaffe后，执行make mattest后，往往出现“Invalid MEX-file"问题，其原因是MATLAB和linux的库冲突，解决的方法是用linux的库（在编译caffe之前大家的opencv等库肯定也早已装好了）

大部分的解决方法是通过export LD_LIBRARY_PATH和 LD_PRELOAD来链接，但是效果不好。最后发现，只有直接去MATLAB下面删除库并重新链接到x86_64-linux-gnu的方法是最好的。具体方法如下：

1.不需要降级gcc和g++，就用linux的自带版本，否则caffe编译不一定通过。我的是14.04的5.4（千万不要先用5去编译caffe再降级用4.4编译matcaffe）

2.不要去用改LIBRARY_PATH的方法，因为很可能不成功，尤其是有倒霉催的anaconda的情况下。

3.找到你的linux库的位置（一般是/usr/lib/x86_64-linux-gnu/)以及MATLAB库的位置（默认是/usr/local/MATLAB/R2014a/sys/os/glnxa64/）。然后写个sh执行下列操作


rm -rf /usr/local/MATLAB/R2014a/sys/os/glnxa64/libstdc++.so.6
ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 /usr/local/MATLAB/R2014a/sys/os/glnxa64/libstdc++.so.6
rm -rf /usr/local/MATLAB/R2014a/bin/glnxa64/libopencv_core.so.2.4
ln -s /usr/lib/x86_64-linux-gnu/libopencv_core.so.2.4.9  /usr/local/MATLAB/R2014a/bin/glnxa64/libopencv_core.so.2.4
rm -rf /usr/local/MATLAB/R2014a/bin/glnxa64/libopencv_imgproc.so.2.4
sudo ln -s /usr/lib/x86_64-linux-gnu/libopencv_imgproc.so.2.4.9  /usr/local/MATLAB/R2017a/bin/glnxa64/libopencv_imgproc.so.2.4
rm -rf /usr/local/MATLAB/R2014a/bin/glnxa64/libopencv_highgui.so.2.4
sudo ln -s /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.9  /usr/local/MATLAB/R2017a/bin/glnxa64/libopencv_highgui.so.2.4
rm -rf /usr/local/MATLAB/R2014a/bin/glnxa64/libfreetype.so.6
sudo ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so.6  /usr/local/MATLAB/R2017a/bin/glnxa64/libfreetype.so.6
