Install CUDA until this appeared in your screen !

Q1: Some times, it warning you that your Nvidia-driver can not communitcate with your GPU, what can you do ?

A1: Well, the only thing you could do is install your cuda in the right way, and reboot your PC. It will be OK.

1. 首先安装 cuda :

sudo apt-get update

sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb

sudo apt-get install cuda

2. 安装基本依赖项：

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler

sudo apt-get install --no-install-recommends libboost-all-dev

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler  

 sudo apt-get install --no-install-recommends libboost-all-dev

 sudo apt-get install python-skimage ipython python-pil python-h5py ipython python-gflags python-yaml  

 sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev  

3. 设置环境变量：

export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH  

也可以在 /etc/profile中进行编辑, 在最后加入：

exportPATH=/usr/local/cuda-8.0/bin:$PATH
exportLD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH

4. 设置CUDA-7.5 SAMPLES：

cuda-install-samples-8.0.sh  ~
cd ~/NVIDIA_CUDA-.0_Samples
cd 1_Utilities/deviceQuery
make 

进入NVIDIA_CUDA-8.0_Samples 会编译很长时间，耐心等待。

执行测试代码： deviceQuery，如果成功结尾会是Result = PASS

此处，可能因为gcc或者g++版本问题，导致无法编译。重新安装一个较老的版本gcc-4.7，然后添加对应的软连接即可编译：

sudo apt-get install -y gcc-4.7
sudo apt-get install -y g++-4.7  
cd /usr/bin
sudo rm gcc 
sudo ln -s gcc-4.7 gcc 
sudo rm g++ 
sudo ln -s g++-4.7 g++ 
#### check it's success or not ? 
ls -al gcc g++ 
gcc --version
g++ --version

如何安装多个版本的 gcc 和 g++，然后实现自动切换？

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
sudo apt update

sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
sudo apt-get install -y gcc-4.8 g++-4.8 gcc-4.9 g++-4.9 gcc- g++- gcc- g++- gcc- g++-

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc- 

sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++- 

sudo update-alternatives --set cc /usr/bin/gcc
sudo update-alternatives --set c++ /usr/bin/g++

如果需要 gcc 3.4.6，还可以安装这２个包： 
gcc34 https://drive.google.com/file/d/0B7S255p3kFXNRTkzQnRSNXZ6UVU/view?usp=sharing 
g++34 https://drive.google.com/file/d/0B7S255p3kFXNV3J3bnVoWGNWdG8/view?usp=sharing 
下载后用 sudo dpkg -i package_name 安装，然后执行：

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc34
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++ 

切换命令：

sudo update-alternatives --config gcc
sudo update-alternatives --config g++

5. 安装BLAS：　　

sudo apt-get install libatlas-base-dev 

6. 安装其他依赖项：

sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev

7. 安装opencv:

#[compiler]
sudo apt-get install build-essential
#[required]
sudo apt-get install cmake git libgtk2.-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
#[optional]
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394--dev  

8. 安装cudnn:

　解压cudnn的包（官网得申请，用网盘搜索能找到最新的），有include和lib64，里面文件复制到对应/usr/local/cuda/对应文件夹里

#进到对应文件夹
sudo cp cudnn.h /usr/local/cuda/include/

#进到对应文件夹
sudo cp lib* /usr/local/cuda/lib64/

#进行一次 
sudo ldconfig -v

9. 安装caffe:

Caffe

git clone https://github.com/BVLC/caffe.git
cp Makefile.config.example Makefile.config  

修改Makefile.config，去掉cudnn的注释，其他的在当前应用场景可不变。

make all
make test
make runtest  

#####################################################

##　　　　　虚拟环境的配置，激活与使用

#####################################################

1. 创建环境并且激活环境：

conda create --name pysot python=3.7
conda activate pysot

2. 安装 其他图像视频处理中常用的依赖项：

conda install numpy pytorch=0.4. torchvision cuda90 -c pytorch
conda install numpy pytorch=1.2.0 torchvision cuda90 -c pytorch

conda install pytorch=1.2.0 torchvision cudatoolkit=10.0 -c pytorch 

pip install torch==1.3.0+cu100 torchvision==0.4.1+cu100 -f https://download.pytorch.org/whl/torch_stable.html

pip install opencv-python pyyaml yacs tqdm colorama matplotlib cython tensorboardX

10. 安装matlab:

Many Tutorials online, we just ignore this part here.

11. can not find "hdf5.h":

# 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

12. 编译caffe的时候，提示：
CXX examples/cifar10/convert_cifar_data.cpp
CXX examples/siamese/convert_mnist_siamese_data.cpp
AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so.1.0.0-rc3

/usr/bin/ld: cannot find -lhdf5
collect2: error: ld returned 1 exit status

make: *** [.build_release/lib/libcaffe.so.1.0.0-rc3] Error 1
wangxiao@GTX980:~/Downloads/caffe-master$
-------------------

怎么破？

do as issue 12. Change the Makefile.config:

# 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

13. 安装 MKL:

MKL与CUDA的环境设置

1. 新建intel_mkl.conf， 并编辑之：

         $ sudo gedit /etc/ld.so.conf.d/intel_mkl.conf

         /opt/intel/lib/intel64

         /opt/intel/mkl/lib/intel64

2. 新建cuda.conf，并编辑之：

         $ sudo gedit /etc/ld.so.conf.d/cuda.conf

         /usr/local/cuda/lib64

         /lib

3. 完成lib文件的链接操作，执行：

         $ sudo ldconfig –v

　　

15. 可能需要添加的东西：

配置Makefile文件（实现对OpenCV3.x的支持）

查找“Derive include and lib directories”一节，修改“LIBRARIES +=”的最后一行，增加opencv_imgcodecs

opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs

16. 运行caffe案例：

. 数据预处理

$ sudo shdata/mnist/get_mnist.sh

. 重建lmdb文件。Caffe支持三种数据格式输入网络，包括Image(.jpg, .png等)，leveldb，lmdb，根据自己需要选择不同输入吧。

$sudo shexamples/mnist/create_mnist.sh

生成mnist-train-lmdb 和 mnist-train-lmdb文件夹，这里包含了lmdb格式的数据集

注：我执行此命令的时候报告说not in gzformat，后来发现是联网下载的mnist数据有问题，然后我就去网上了下载了mnist数据集，后在ubuntu上手动解压的，再执行后面的命令。

. 训练mnist
$ sudo shexamples/mnist/train_lenet.sh

17. when compile caffe:

what the fuck :::

...

OK, 改为ubuntu Kylic版本了，哎，还是麒麟好用啊。。。坑逼

---

18. when use the matlab demo from caffe file:

　　after make matcaffe, and it warning me it's OK. and when run the demo, it shown me the errors like this:

　　Invalid MEX-file '/home/wangxiao/Downloads/caltech_256_caffe_master/matlab/+caffe/private/caffe_.mexa64': libcudart.so.7.5: cannot open shared object file: No such file or directory

　　What should I do for this ??

　　

　　 You must remember the following operation, because it really worked well ! Yeah !!!

---

　　error while loading shared libraries: libcudart.so.7.5: cannot open shared object file: No such file or directory

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

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

　　今天悲剧的发现, 执行了 64-bit 之后出现错误:　　　

　　wangxiao@AHU:~/Downloads/caffe-master$ sudo ldconfig /usr/local/cuda/lib64

　　/sbin/ldconfig.real: /usr/local/cuda/lib64/libcudnn.so.5 is not a symbolic link

　　不知道问题何在啊?怎么解决???　　

　　##############################################
　　##  有时候需要更新软链接:
　　
　　cd /usr/local/cuda/lib64/  
　　sudo rm -rf libcudnn.so libcudnn.so.7.5  
　　sudo ln -s libcudnn.so.7.5.48 libcudnn.so.7.5  
　　sudo ln -s libcudnn.so.7.5 libcudnn.so

19. When compile caffe, some times it always shown you a mistake like this:

CXX src/caffe/util/db_leveldb.cpp
In file included from src/caffe/util/signal_handler.cpp:7:0:
./include/caffe/util/signal_handler.h:4:34: fatal error: caffe/proto/caffe.pb.h: No such file or directory
#include "caffe/proto/caffe.pb.h"
^
compilation terminated.
The bug is not reproducible, so it is likely a hardware or OS problem.
make: *** [.build_release/src/caffe/util/signal_handler.o] Error 1
make: *** Waiting for unfinished jobs....
^Cmake: *** [.build_release/src/caffe/util/math_functions.o] Interrupt
make: *** [.build_release/src/caffe/net.o] Interrupt
make: *** wait: No child processes. Stop.

Do you how to solve this problem ???  Just becase the lost of the file : caffe.pb.h, and this file is actually generated from the process of compile. Do the following operation will help you solve the problem:

　　Just input make in your terminal:  make

　　Then, press ctrl+c to stop it, and input: make -j8

　　All process will be normal now !

　　Here is a figure to help you understand this all process.

 20. You also maybe meet a error like this:

Just add a word in you Makefile, following:

LIBRARIES += opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs

21. 利用caffe 的matlab借口提取feature的时候：碰到了这个问题：怎么破 ？

　　　　

　　Undefined function 'caffe_' for input arguments of type 'char'.

　　Error in caffe.set_mode_gpu (line 5)
　　caffe_('set_mode_gpu');

　　Error in Copy_of_Label_all_ (line 11)
　　caffe.set_mode_gpu();

　　答：因为没有编译matlab接口，即：make matcaffe 执行这句，完了之后，你就发现，yeah，可以了。。。

22. protobuf 的下载与安装

　　from: https://github.com/protocolbuffers/protobuf/tree/master/src

You can get the source by "git clone" our git repository. Make sure you have also cloned the submodules and generated the configure script (skip this if you are using a release .tar.gz or .zip package):

$ git clone https://github.com/protocolbuffers/protobuf.git
$ cd protobuf
$ git submodule update --init --recursive
$ ./autogen.sh
To build and install the C++ Protocol Buffer runtime and the Protocol Buffer compiler (protoc) execute the following:

$ ./configure
$ make
$ make check
$ sudo make install
$ sudo ldconfig # refresh shared library cache.

　　

23. 将 wide residual network 的 python 脚本生成 其对应的 protext 文件,出现问题:

wangxiao@AHU:~/Downloads/caffe-master$ python ./python/wide_residual_network.py
Traceback (most recent call last):
File "./python/wide_residual_network.py", line 62, in <module>

　　 搜到一个答案,但是不知所云:

　　　　http://stackoverflow.com/questions/15232832/python-regex-attributeerror-nonetype-object-has-no-attribute-groups

　　哎 坑啊 ...

24. 要用 CUDNN，因为训练速度会提升好几倍！！！

25. 编译 caffe 出现：

XX src/caffe/layers/cudnn_sigmoid_layer.cpp
CXX src/caffe/layers/deconv_layer.cpp
src/caffe/net.cpp:8:18: fatal error: hdf5.h: No such file or directory

make: *** Waiting for unfinished jobs....
wangxiao@csdl:~/pedestrian_attributes/43_attribute_caffe_master_$ ^C
wangxiao@csdl:~/pedestrian_attributes/43_attribute_caffe_master_$

那么，怎么解决这个问题？添加两行路径：

 　　/usr/include/hdf5/serial 

　　/usr/lib/x86_64-linux-gnu/hdf5/serial

　　

 26. caffe 配置 python 环境变量: 参考博文:http://blog.csdn.net/yingyujianmo/article/details/51014440

　

　　添加环境变量 
　　　　vim ~/.bashrc
　　将export PYTHONPATH=/home/wanghh/caffe/python:$PYTHONPATH添加到文件中。 
　　　　source ~/.bashrc
　　这样，在其他地方打开python，也可以import caffe了。

　　

---

27. caffe 配置 python, some times, it shown us: no module named caffe: 

　　at this moment, maybe you should add those codes into your file, like :

　　

　　then, you can check it again. It will be OK.

28. when install new softwares, I find this error: 

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:

==>> Update your MatConvnet version. It indeed contain such errors in this version.

30. json_parser_read.hpp:257:264: error: ‘type name’ declared as function returning an array escape 

when compile caffe file in SSD, it shown me the error like this:

json_parser_read.hpp:257:264: error: ‘type name’ declared as function returning an array escape

Just like this blog said, you need do this:

修改json_parser_read.hpp：打开文件夹Document，选中computer，在搜索json_parser_read.hpp，找到该文件的路径之后用如下命令打开

sudo gedit /usr/include/boost/property_tree/detail/json_parser_read.hpp

将257行开始的escape代码段注释掉即可，如下：

/*escape
                    =   chset_p(detail::widen<Ch>("\"\\/bfnrt").c_str())
                            [typename Context::a_escape(self.c)]
                    |   'u' >> uint_parser<unsigned long, 16, 4, 4>()
                            [typename Context::a_unicode(self.c)]

==>> do the following opeartions:

1.Remove installed OpenCV version to avoid mess up later

pip3 uninstall opencv-python
2.Lower you python version to 3.5(current version 3.6 has different problems with conda, which we will use to install OpenCV)

conda install python=3.5
3.Finally use conda, to install working version of OpenCV 

conda install -c menpo opencv3
sudo apt-get install libgtk-3-dev

　　

34. when running a tensorflow code, it shown me a error: 

ImportError: libcudnn.so.6: cannot open shared object file: No such file or directory

Failed to load the native TensorFlow runtime.

==>> well, this is because the version of tensorflow. Currently, the most recent tensorflow is version 1.3.0, and it need cudnn v6+. but my machine still use the cudnn v5.1.

Thus the error occured. You can sovle this problem by install tensorflow v1.2.0, as following:

sudo pip install --user tensorflow==1.2.0

gcc version 5.4.1 20160904 (Ubuntu 5.4.1-2ubuntu1~14.04) 

At this moment, you already installed gcc and g++ V5 successfully. You just remove the old super-link and add the new one: 

cd /usr/bin
sudo rm gcc 
sudo ln -s gcc-5 gcc 
sudo rm g++ 
sudo ln -s g++-5 g++
