虚拟机Ubuntu16，caffe环境搭建

虚拟机下的Ubuntu16.04+caffe+onlycup

官网的step很重要，要跟着官网，的步骤来：http://caffe.berkeleyvision.org/installation.html

然后对照：http://blog.csdn.net/firethelife/article/details/51926754

======================【关于注意和报错】===================

-------------------------------------------------------------------------------------

caffe下make 的时候遇到的一些找不到ldhf5之类的错误，则要安装libhdf5,如下解决：

sudo apt-get install libhdf5-dev

-------------------------------------------------------------------------------------

【http://www.linuxidc.com/Linux/2016-07/132860.htm】

首先安装必要的库，有的依赖库我是已经安装过的，具体安装的先后关系已经忘了。如果出现有些依赖关系不满足的错误，可以再安装库：

$ sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev    # 必要的基本库

根据上面的链接下载OpenCV3.1.0版本，并进行解压，解压之后进入安装文件目录:

$ cd opencv-3.1.0
$ mkdir build          #创建build文件夹
$ cd opencv-3.1.0/build
$ cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..  

----------------------------------------------------------------------------------

OpenBLAS：

The default directory is /opt/OpenBLAS     /*这个是默认安装路径*/

$ git clone https://github.com/xianyi/OpenBLAS.git

【http://www.linuxdiyf.com/linux/15610.html】

则需要安装，安装的步骤如下：

（1）git clone https://github.com/xianyi/OpenBLAS.git

（2）cd OpenBLAS

（3）make FC=gfortran （如果没有安装gfortran,执行sudo apt-get install gfortran）

(4) make install (将OpenBLAS安装到/opt下)

装好后，对应 caffe下Makefile.config修改如下：

# BLAS choice:
# atlas for ATLAS (default)
# mkl for MKL
# open for OpenBlas
BLAS := open
# Custom (MKL/ATLAS/OpenBLAS) include and lib directories.
# Leave commented to accept the defaults for your choice of BLAS
# (which should work)!
BLAS_INCLUDE := /opt/OpenBLAS/include
BLAS_LIB := /opt/OpenBLAS/lib

-----------------------------------------------------------------------------------

caffe，，，make 的时候会发生一些错误，查看caffe下Makefile.config，修改：

# Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/

其中：/usr/include/hdf5/serial/是hdf5的位置。

---------------------------------------------------------------------------------------

【http://blog.csdn.net/lanxuecc/article/details/51997919】

runtest时会报一个错：：build_release/tools/caffe: error while loading shared libraries: libopenblas.so.0: cannot open shared object file: No such file or directory，解决方法：在/usr/lib/下建立一个 软链接将 libopenblas.so.0指向/openbls安装目录/lib/ libopenblas.so.0

-----\

在/usr/lib/下建立一个 软链接将 libopenblas.so.0指向/openbls安装目录/lib/ libopenblas.so.0
ln -s /opt/OpenBLAS/lib/libopenblas.so.0 /usr/lib/libopenblas.so.0

------------------------------------------------------------------------------------

感想：在Windows和虚拟机Ubuntu16下都搭好了环境了，好想大声喊一句：鬼知道我这四天经历了什么。。。。幸好你没有放弃！！！

花了2天的时间明白：cuda是英伟达的显卡，而我的机子是【计算机右键-属性-适配器-（最后一项）显示适配器：AMD】AMD的，所以装了cuda进不去Ubuntu的图形界面，在这里开启了各种重装的坎坷路程。。。。整整话了两天啊。。。我的妈呀！！！幸好，坚持了下来！！：）加油。
