ubuntu14.04 caffe+cuda-7.0 Configuration

First install Cuda:

Download from the NVIDIA official website: Cuda-repo-ubuntu1404-7-0-local_7.0-28_amd64.deb, there are two types of run and Deb, heavily recommended Deb format, easy to install

CD to the directory where Cuda-repo-ubuntu1404-7-0-local_7.0-28_amd64.deb is located, such as mine:

CD ~/software/cuda-repo-ubuntu1404-7-0-local_7.0-28_amd64.deb

Perform:

sudo dpkg-i cuda-repo-ubuntu1404-7-0-local_7.0-28_amd64.deb;

sudo apt-get update

sudo apt-get-y install cuda;

And then, here, more than 6.5 will automatically install the graphics driver, so the installation will appear after the Nvidia driver

Then configure the environment variables

Add cuda.conf files to/ETC/LD.SO.CONF.D

VI cuda.conf

/usr/local/cuda-7.0/lib64

Add the following in/etc/profile or ~/.BASHRC:

#cuda env
Path=/usr/local/cuda-7.0/bin: $PATH
Export PATH

Export ld_library_path=/usr/local/cuda-7.0/libnvvp:/usr/local/cuda-7.0/lib64: $LD _library_path

Final execution:

sudo ldconfig

and source ~/.BASHRC

On the line, and finally:

sudo reboot

For caffe installation configuration, refer to:

Http://www.cnblogs.com/platero/p/3993877.html

It is not recommended to install Anaconda, too large and if we do not need a python-like library, and there may be a variety of Python library can not find the problem

Finally, it is recommended to compile the caffe using Cmake-gui

The installation method is:

sudo apt-get install Cmake-qt-gui

Finally, a makefile file is generated and then executed under the appropriate path:

sudo make all

sudo make install

sudo make runtest

Just do it.

A final note:

I loaded the cuda before finally because I was in the configuration of Java when I used a wrong command caused me to delete the original cuda all;

and then I'm going to install it again. Then there are all sorts of problems in the middle, like :

http://blog.csdn.net/jkxsanger/article/details/8983107

No cuda-capable device is detected

The reference to this scheme is not resolved (but the direction is indicated):

Step1: Re-install NVIDIA CUDA Toolkit

sudo sh cuda_5.0.35_linux_64_rhel6.x-1.run

Step2: After successful installation, follow the prompts to configure the/etc/ld.so.conf file

My system is 64 bit so vim/etc/ld.so.conf add

/usr/local/cuda-5.0/lib64
/usr/local/cuda-5.0/lib

Save modification Exit:

Execute Command ldconfig

Step3: If you want more than one person to use the CUDA programming environment and the corresponding hardware resources

Modify the/etc/profile file

Export Path=/usr/local/cuda-5.0/bin: $PATH
Export ld_library_path=/usr/local/cuda-5.0/lib:/usr/local/cuda-5.0/lib64: $LD _library_path

The Final Solution is:

Use the following command to first uninstall Cuda:

sudo apt-get--purge Remove Cuda

The previous step is just a partial uninstall and then need to be completely removed

sudo apt-get autoremove cuda

Then you need to completely uninstall the Nvidia driver:

Su doapt-get remove--purge nvidia-*sudo apt-' nouveau ' | sudo tee-a/etc/modules  

Reboot and then perform the new installation of the cuda-7.0 using the first method.
