Ubuntu 16.04 Installation Guide

PredragBoksic edited this page Sep 19, 2017 · 3 revisions

The following guide includes the how-to instructions for the installation of BVLC/Caffe on Ubuntu 16.04 with Cuda Toolkit 8.0.61-1, CUDNN library 7.0.2.38-1 and OpenCV version 2.x or 3.3. This guide also covers the KUbuntu distribution and the related distributions.

Execute these commands first:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y build-essential cmake git pkg-config
sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libhdf5-serial-dev protobuf-compiler libatlas-base-dev libboost-all-dev libgflags-dev libgoogle-glog-dev liblmdb-dev

# (Python general)
sudo apt-get install -y python-pip

# (Python 2.7 development files)
sudo apt-get install -y python-dev
sudo apt-get install -y python-numpy python-scipy

# (or, Python 3.5 development files)
sudo apt-get install -y python3-dev
sudo apt-get install -y python3-numpy python3-scipy
 
# (OpenCV 2.4)
sudo apt-get install -y libopencv-dev

(or, OpenCV 3.3 - see the instructions below)

If you own an NVIDIA graphics card, see the instructions for the installation of NVIDIA Graphics Driver, Cuda Toolkit and CUDNN library at the end of this document, or by clicking https://github.com/BVLC/caffe/wiki/Ubuntu-16.04-Installation-Guide#the-gpu-support-prerequisites.

For the instructions on how to use the OpenCV version 3.3, please see https://github.com/BVLC/caffe/wiki/OpenCV-3.3-Installation-Guide-on-Ubuntu-16.04

The configuration settings will differ for OpenCV 3.3 as you can see above, but here we continue with the basic settings that imply the version 2.x.

Go to the https://github.com/BVLC/caffe and download the zip archive. Unpack it to ~/bin/ or any other location. Enter the caffe-master directory in the terminal window. Note that only the version 1.0RC5 compiles well at this moment, so download the 1.0RC5 version from https://github.com/BVLC/caffe/archive/rc5.zip. If you download the 1.0 version from https://github.com/BVLC/caffe/archive/1.0.zip, you need to edit the file /src/caffe/util/blocking_queue.cpp. After the line 89, and the new line that contains the following:

template class BlockingQueue<Datum*>;

Copy the Makefile.config.example to Makefile.config like this:

cp Makefile.config.example Makefile.config

and open it for editing (with a text editor). I use the kate editor for this purpose, so the command that I execute goes as follows. You first need to install the kate editor with:

sudo apt-get install kate

and then you can edit the configuration file with:

kate ./Makefile.config &

The following line in the configuration file tells the program to use CPU only for the computations.

CPU_ONLY := 1

CPU_ONLY option is enabled for a computer without any NVIDIA graphics card and it is typical for the installation of Caffe inside the typical virtual machine. (Notice that there is a special type of virtual machine inside the Ubuntu host machine that can access the physical NVIDIA graphics card directly. See https://github.com/NVIDIA/nvidia-docker)

The default option value is to use GPU and CPU computation. Change the line if needed, by commenting it out (# CPU_ONLY := 1) if you have the NVIDIA graphics card with the proprietary driver, CUDA toolkit and CUDNN installed. Jump to the end of this guide to read about how to install the GPU support prerequisites.

The Makefile.config should contain the following lines, so find them and fill them in.

PYTHON_INCLUDE := /usr/include/python2.7 /usr/lib/python2.7/dist-packages/numpy/core/include

(for some Ubuntu 16.04 users, the path may be different)

PYTHON_INCLUDE := /usr/include/python2.7 /usr/local/lib/python2.7/dist-packages/numpy/core/include

WITH_PYTHON_LAYER := 1

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

(For ways to create an isolated Python environment, explore the topic of virtual environments here: http://docs.python-guide.org/en/latest/dev/virtualenvs/)

If you encounter a missing CUDA error with CUDA version 8.0, find this line in the Makefile.config:

CUDA_DIR := /usr/local/cuda

And replace it with this line:

CUDA_DIR := /usr/local/cuda-8.0

Let's return to the unpacked Caffe directory caffe-master and execute these commands:

cd python

for req in $(cat requirements.txt); do pip install $req; done

NOTE: If the Ubuntu operating system was updated, perhaps the Python layer needs to be updated and recompiled because the Python module no longer works. Perform this step again in that case.

for req in $(cat requirements.txt); do pip install $req; done

In case of any problems, try:

for req in $(cat requirements.txt); do sudo -H pip install $req --upgrade; done

The default Python version is 2. You can edit the Makefile.conf to enable the Python 3, but this will fail during the linking phase: boost_python3 cannot be found on Ubuntu 16.04. Instead, this file should be /usr/lib/x86_64-linux-gnu/libboost_python-py35.so.1.58.0. This requires further testing.


The next step is to build Caffe:

cd ..

(now you are in caffe-master directory)

The build process will fail in Ubuntu 16.04. Edit the Makefile with an editor such as

kate ./Makefile

and replace this line:

NVCCFLAGS += -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)

with the following line

NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)

Also, open the file CMakeLists.txt and add the following line:

# ---[ Includes
set(${CMAKE_CXX_FLAGS} "-D_FORCE_INLINES ${CMAKE_CXX_FLAGS}")

(See the discussion at: https://github.com/BVLC/caffe/issues/4046)

Next, build the Caffe with the following command.

make all
make test
make runtest
make pycaffe      -should be finished already, so you can omit this one
make distribute

Note that the build process can be sped up by appending -j $(($(nproc) + 1)) to the above commands, which distributes the build across the available processors on your system. For example:

make all

can become

make all -j $(($(nproc) + 1))

In order to make the Python work with Caffe, open the file ~/.bashrc for editing in your favorite text editor. There, add the following line at the end of file:

export PYTHONPATH=/path/to/caffe-master/python:$PYTHONPATH

You can also execute that same line immediately in the terminal as a command for immediate effects, or in general execute:

source ~/.bashrc 

In order to use the Caffe binaries, libraries, or include files, they need to be reachable through the search path, so one solution is to copy them into their respective directories: from the distribute directory to the /usr/bin or /usr/lib or /usr/include.

The binary models can be download with the following script. In caffe-master directory,

cd scripts
./download_model_binary.py ../models/bvlc_alexnet/
./download_model_binary.py ../models/bvlc_googlenet/
./download_model_binary.py ../models/bvlc_reference_caffenet/
./download_model_binary.py ../models/bvlc_reference_rcnn_ilsvrc13/
./download_model_binary.py ../models/finetune_flickr_style/

For most Linux programs compiled from source, you can attempt to build a package that can be installed and uninstalled with a single click.

sudo apt-get install checkinstall

Now, when you execute the:

sudo checkinstall

and fill out a form with some easy questions, you will have the package made automatically. However, this uses the command "make install" in the background, which will fail, because the Caffe project does not have the target "install" configured in the Makefile.


The GPU support prerequisites

In Ubuntu desktop, enable the use of proprietary drivers in the Software & Updates Center for your desktop and install the NVIDIA graphics driver from the main Ubuntu package repository. See https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia

In Kubuntu 16.04, you need to enable the use of proprietary drivers (in System Settings -> Driver Manager).

Discover which driver number you need with:

sudo ubuntu-drivers devices

The LATEST version of Cuda Toolkit 8.0 is available from the NVIDIA website. Download the Cuda Toolkit 8.0 network installer and the CUDNN 7 package from the NVIDIA site, after registering and filling out the forms. https://developer.nvidia.com/cuda-downloads

Install the Cuda Toolkit 8.0 package manually in the terminal as instructed at the website. For example:

sudo apt-get update && sudo apt-get install wget -y --no-install-recommends
wget "https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_8.0.61-1_amd64.deb"
sudo dpkg -i cuda-repo-ubuntu1604_8.0.61-1_amd64.deb
sudo apt-get update
sudo apt-get install cuda

Register an account in order to download and install the Debian (.deb) package that contains the CUDNN library from https://developer.nvidia.com/cudnn.

sudo dpkg -i libcudnn7_7.0.2.38-1+cuda8.0_amd64.deb 
sudo dpkg -i libcudnn7-dev_7.0.2.38-1+cuda8.0_amd64.deb

You can check your Ubuntu environment variables after the reboot, by executing the command:

export

Edit the Makefile.config in Caffe directory accordingly (as described in the config file itself) and recompile the Caffe to support the GPU computation. To recompile, first, execute make clean.


Test the Caffe framework with DeepDream project

A fun way to try the Caffe framework for python is to use it in the DeepDream project. Visit the following site for specific source code: https://github.com/google/deepdream One of the trained neural networks used in this procedure can be found here: http://places.csail.mit.edu/model/googlenet_places205.tar.gz Before you begin, you need to prepare the Ubuntu 16.04 system for the use of IPython and Jupyter. For these instructions, see: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-jupyter-notebook-to-run-ipython-on-ubuntu-16-04

Then, you can add Python 2 and Python 3 kernels for the execution of IPython Notebooks (usually with the command ipython notebook filename).

python2 -m pip install ipykernel
python2 -m ipykernel install --user

python3 -m pip install ipykernel
python3 -m ipykernel install --user
