Caffe installation guide

Task: install Caffe framework on Ubuntu 15.04 with CUDA 7.5

Link to Kubuntu 15.04: kubuntu-15.04-desktop-amd64.iso

Link to CUDA 7.5: Download (1.1 GB)

 

Update the system

• Install build essentials:
  • sudo apt-get install build-essential
• Install latest version of kernel headers:
  • sudo apt-get install linux-headers-`uname -r`

Install CUDA

• Install curl (for the CUDA download):
  • sudo apt-get install curl
• Download CUDA 7.5 to Downloads folder
  • cd Downloads
  • Download cuda_7.5.18_linux.run from https://developer.nvidia.com/cuda-downloads
• Make the downloaded installer file runnable:
  • chmod +x cuda_7.5.18_linux.run

• Run the CUDA installer:
  • sudo ./cuda_7.5.18_linux.run --kernel-source-path=/usr/src/linux-headers-`uname -r`/
    • Accept the EULA
    • Do NOT install the graphics card drivers (since we are in a virtual machine)
    • Install the toolkit (leave path at default)
    • Install symbolic link
    • Install samples (leave path at default)
• Update the library path
  • echo 'export PATH=/usr/local/cuda/bin:$PATH' >> ~/.bashrc
  • echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/lib' >> ~/.bashrc
  • source ~/.bashrc

Install dependencies

• sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev protobuf-compiler gfortran libjpeg62 libfreeimage-dev libatlas-base-dev git python-dev python-pip libgoogle-glog-dev libbz2-dev libxml2-dev libxslt-dev libffi-dev libssl-dev libgflags-dev liblmdb-dev python-yaml
• sudo easy_install pillow

Install Caffe

• Download Caffe:
  • cd ~
  • git clone https://github.com/BVLC/caffe.git

• Install python dependencies for Caffe:
  • cd caffe
  • cat python/requirements.txt | xargs -L 1 sudo pip install
• Add a couple of symbolic links for some reason:
  • sudo ln -s /usr/include/python2.7/ /usr/local/include/python2.7
  • sudo ln -s /usr/local/lib/python2.7/dist-packages/numpy/core/include/numpy/ /usr/local/include/python2.7/numpy
• Create a Makefile.config from the example:
  • cp Makefile.config.example Makefile.config
  • Edit Makefile.config
    • Uncomment the line # CPU_ONLY := 1 (In a virtual machine we do not have access to the the GPU)
    • Under PYTHON_INCLUDE, replace /usr/lib/python2.7/dist-packages/numpy/core/include with /usr/local/lib/python2.7/dist-packages/numpy/core/include (i.e. add /local)
    • Add reference to hdf5
      INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/lib/x86_64-linux-gnu/hdf5/serial/include
      LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial
• Add “opencv_imgcodecs” to the Makefile.
  • (LIBRARIES += glog gflags protobuf leveldb snappy \
    lmdb boost_system hdf5_hl hdf5 m \
    opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs)
• Compile Caffe:
  • make pycaffe
  • make all
  • make test

Congralutations!!! You have successfully installed Caffe into Ubuntu 15.04 with CUDA 7.5. Let’s enjoy it now.

You can play with it in python. But I prefer ipython notebook since it allows us to debug to have a deep insight into what happens in the code, not just a black box.

( In case ipython notebook runs into error, please run

For 4.0 and above You need to install the notebook app separately from https://github.com/jupyter/notebook

pip install jupyter
