学习：Ubuntu14.04编译caffe问题记录

问题一：libunwind.so.8: undefined reference

//usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_index_end@XZ_5.0' 

//usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_index_size@XZ_5.0' 

//usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_index_buffer_decode@XZ_5.0' 

//usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_stream_footer_decode@XZ_5.0' 

//usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_stream_buffer_decode@XZ_5.0' 

//usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_index_uncompressed_size@XZ_5.0'

解决方法：

1.

ldconfig -p | grep lzma

    liblzma.so.5 (libc6,x86-64) => /lib/x86_64-linux-gnu/liblzma.so.5

    liblzma.so.5 (libc6) => /lib/i386-linux-gnu/liblzma.so.5

    liblzma.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/liblzma.so

2.

export LD_LIBRARY_PATH=/lib/x86_64-linux-gnu/

问题二：

libcudart.so.7.5: cannot open shared object file: No such file or directory

解决方法：

1）管理员直接加入

32-bit：sudo ldconfig /usr/local/cuda/lib

64-bit：sudo ldconfig /usr/local/cuda/lib64

2）服务器加入自己路径下的设置中

首先打开bashrc文件：gedit ~/.bashrc

在文件末尾加入环境变量，如64-bit：export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64"

保存文件退出，在终端保存加载设置：soucre ~/.bashrc 

3）临时性加入，下次登录后需要重新加入

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64"

问题三：

libhdf5_hl.so.10: cannot open shared object file: No such file or directory

我用anaconda2

解决方法：

export LD_LIBRARY_PATH=/path/to/your/anaconda2/lib:$LD_LIBRARY_PATH

我的是

export LD_LIBRARY_PATH=/home/k/anaconda2/lib:$LD_LIBRARY_PATH

问题四:

fatal error: caffe/proto/caffe.pb.h: No such file or directory  #include "caffe/proto/caffe.pb.h"

解决方法:

# In the directory you installed Caffe to

protoc src/caffe/proto/caffe.proto --cpp_out=.

mkdir include/caffe/proto

mv src/caffe/proto/caffe.pb.h include/caffe/proto

问题五:

error while loading shared libraries: libprotoc.so.9: cannot open shared object file: No such file or directory

解决方法:

export LD_LIBRARY_PATH=/usr/local/lib/

问题六:undefined reference to `caffe::db::GetDB(std::string const&)'

解决方法:

export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

问题七:

make pycaffe错误:

CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp

python/caffe/_caffe.cpp:1:52: fatal error: Python.h: No such file or directory

 #include  // NOLINT(build/include_alpha)

                                                    ^

compilation terminated.

make: *** [python/caffe/_caffe.so] Error 1

解决方法：

Makefile.config中anaconda路径不对

问题八:

如果发现编译的时候没有找到cudnn相关的头文件，那么有可能是用了低版本的cudnn，特别是cudnnv4，下载cudnnv5和新版caffe然后把include和lib分别放到cuda响应的include和lib64上然后重新编译。

问题九：

undefined symbol: _ZN5caffe13CuDNNLCNLayerIfED1Ev

找不到libcaffe相关库文件

export LD_LIBRARY_PATH到你编译后使用的libcaffe.so所在位置

wenti10

error while loading shared libraries: libmkl_rt.so: cannot open shared object file: No such file or directory

解决方法：/etc/ld.so.conf.d/ 文件夹下增加了一个文件命名为intel_mkl_settings.conf。 然后在里面添加MKL库路径

             /opt/intel/mkl/lib/intel64

wenti11、error while loading shared libraries: libcudart.so.5.5: cannot open shared object file: No such file or directory

解决方法：

32-bit: sudo ldconfig /usr/local/cuda/lib

64-bit: sudo ldconfig /usr/local/cuda/lib64

Q8:make: Nothing to be done for `all' 解决方法

1.这句提示是说明你已经编译好了，而且没有对代码进行任何改动。

若想重新编译，可以先删除以前编译产生的目标文件：
make clean
然后再
make
 

2.出现这种情况解决方法：

a.make clean 清除安装时留下的文件

b.在运行一下ldconfig

c.再make 可运行出结果

Q9:使用caffe的python接口时,很多人都会遇到如下问题:

from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \ImportError: libcaffe.so.1.0.0-rc3: cannot open shared object file: No such file or directory2

这个错误目前非常普遍,在Google上也可以搜索到非常多的讨论,大多数人提出的解决方法是把caffe-master/python和caffe-master/build/lib目录添加到~/.bashrc中,但是问题在于需要修改bashrc,可能会带来很多意想不到的问题.

造成这个问题的主要原因在于使用make进行编译,导致import caffe时找不到静态链接库.

现给出两种比较安全的解决方案:
(1) 在python 代码中加入如下代码:

import os, sysold_path = os.getcwd()caffe_root = "caffe-master"os.chdir(caffe_root + "/python")import caffeos.chdir(old_path)

这部分代码就是先切换到caffe的python目录,然后导入caffe库,然后在切换回原来目录.

(2) 其实找不到libcaffe.so.1.0.0-rc3主要原因在于使用了make进行编译,使得caffe的python接口只能在这个目录下面才能找得到这个库.解决办法是使用cmake进行编译:

cd caffe-master   mkdir build   cd build   cmake ..

这样编译后如果要在python中使用caffe,只需要将caffe的python目录添加到sys.path之中即可:

import os   caffe_root = "caffe-master"   os.path.append(caffe_root + "/python")
