  # Ubuntu Installation
  
  **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from packages, install the library and latest driver separately; the driver bundled with the library is usually out-of-date.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](installation.html#compilation).
