Install Caffe on Ubuntu 14.04 (GPU)

About the installation procedure of Caffe. The one I wrote before was quite subtle, so I rewrote it. (I'm just Chainer and I don't use Caffe.) Previous one: Install Caffe on Ubuntu 14.04 (CPU mode)

I tried it on ubuntu 14.04. Well, it's the same as the official website. I will write a memo.

CUDA installation

#Install the latest version
$ wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_7.5-18_amd64.deb
$ sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb
$ sudo apt-get update
$ sudo apt-get install cuda

cuDNN It seems that it will be faster if cuDNN is introduced. (Nvidia Developer registration required) You don't have to put it in.

#Register and download from your browser
$ tar xvf cudnn-7.5-linux-x64-v5.0-rc-tgz
$ sudo cp cuda/include/cudnn.h /usr/local/cuda/include
$ sudo cp cuda/lib64/* /usr/local/cuda/lib64

Dependency installation

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

Download Caffe

#If git is not included
$ sudo apt-get install git

#Place it directly under home. If you understand, please go wherever you like.
$ cd
$ git clone https://github.com/BVLC/caffe.git

Makefile.config settings

If you don't use cudnn, you can leave it as it is

$ cd caffe
$ cp Makefile.config.example Makefile.config

Uncomment line 5 if you use cnDNN

Makefile.config


# USE_CUDNN := 1
↓
USE_CUDNN := 1

compile

Parallel processing can be done by doing $ make -j4 all. The number is the number of CPU cores. It takes time, so it is recommended to do it with full power.

$ make all
$ make test
$ make runtest

If all the tests pass, the caffe environment construction is complete. If it fails, fix the problem, then do $ make clean and start over with $ make all.

Building an environment for using Caffe with Python

python system

$ sudo apt-get install python-dev python-pip python-numpy python-skimage gfortran

Install required libraries with pip

$ sudo pip install -r ~/caffe/python/requirements.txt

compile

$ make pycaffe

Pass through. (Bash example)

$ echo 'export PYTHONPATH=~/caffe/python/:$PYTHONPATH' >> ~/.bashrc
#To reflect
$ source ~/.bashrc

later

$ python
>>> import caffe

OK if caffe is loaded with.
