ubuntu 安装caffe(特别注意：ubuntu18.0.4 安装GPU版的caffe的命令是：sudo apt install caffe-cuda,而不是很多资料上的caffe-gpu)

Ubuntu Installation

For Ubuntu (>= 17.04)

Installing pre-compiled Caffe

Everything including caffe itself is packaged in 17.04 and higher versions. To install pre-compiled Caffe package, just do it by

sudo apt install caffe-cpu

for CPU-only version, or

sudo apt install caffe-cuda

for CUDA version. Note, the cuda version may break if your NVIDIA driver and CUDA toolkit are not installed by APT.

Installing Caffe from source

We may install the dependencies by merely one line

sudo apt build-dep caffe-cpu        # dependencies for CPU-only version
sudo apt build-dep caffe-cuda       # dependencies for CUDA version

It requires a deb-src line in your sources.list. Continue with compilation.

For Ubuntu (< 17.04)

General dependencies

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

CUDA: Install by apt-get or the NVIDIA .run package. The NVIDIA package tends to follow more recent library and driver versions, but the installation is more manual. If installing from packages, install the library and latest driver separately; the driver bundled with the library is usually out-of-date. This can be skipped for CPU-only installation.

BLAS: install ATLAS by sudo apt-get install libatlas-base-dev or install OpenBLAS by sudo apt-get install libopenblas-dev or MKL for better CPU performance.

Python (optional): if you use the default Python you will need to sudo apt-get install the python-dev package to have the Python headers for building the pycaffe interface.

Compatibility notes, 16.04

CUDA 8 is required on Ubuntu 16.04.

Remaining dependencies, 14.04

Everything is packaged in 14.04.

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

Remaining dependencies, 12.04

These dependencies need manual installation in 12.04.

# glog
wget https://github.com/google/glog/archive/v0.3.3.tar.gz
tar zxvf v0.3.3.tar.gz
cd glog-0.3.3
./configure
make && make install
# gflags
wget https://github.com/schuhschuh/gflags/archive/master.zip
unzip master.zip
cd gflags-master
mkdir build && cd build
export CXXFLAGS="-fPIC" && cmake .. && make VERBOSE=1
make && make install
# lmdb
git clone https://github.com/LMDB/lmdb
cd lmdb/libraries/liblmdb
make && make install

Note that glog does not compile with the most recent gflags version (2.1), so before that is resolved you will need to build with glog first.

Continue with compilation.
