# 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. |
|
|
|
|
|
[Package status of CPU-only version](https://launchpad.net/ubuntu/+source/caffe) |
|
|
|
|
|
[Package status of CUDA version](https://launchpad.net/ubuntu/+source/caffe-contrib) |
|
|
|
|
|
**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](installation.html#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 |
|
|
sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-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from packages, install the library and latest driver separately; the driver bundled with the library is usually out-of-date.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, 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](installation.html#compilation). |
