Installing NuPIC on Ubuntu
Clone this wiki locally
This was tested on Ubuntu 12.04.5 for both 32bit and 64bit and on Ubuntu 14.04 LTS 64bit. There are known problems with Ubuntu 14.10. It assumes you have nothing except what was installed along with the Ubuntu ISO. However, since the creation of this document, there have been changes to the nupic build configuration that invalidates these instructions for 32-bit systems. See Installing NuPIC on Ubuntu 32bit for more information on 32 bit install.
sudo apt-get update sudo apt-get upgrade # optional
Install required packages
These may already be installed, depending on your system.
sudo apt-get install git python-dev python-pip automake libtool libssl-dev g++ cmake mysql-server libpcre3-dev pip install numpy
NOTE: During this installation, you may be prompted to enter a MySQL password for the
rootuser. If you provide your own root password, you will need to update your MySQL settings in the NuPIC configuration file.
git: for cloning the NuPIC repository
python-dev: to get Python headers for compiling C++ with SWIG
python-pip: for python package installation of required NuPIC python dependencies
automake: for C++ build
libtool: GNU tool for creating portable compiled binaries
libssl-dev: encryption libraries
g++: GNU C++ compiler
cmake: cross-platform, open-source make system
mysql-server: Used for swarming
libpcre3-dev: Perl Compatible Regular Expressions development library (for SWIG compilation below, only required for 32b systems)
numpy: Python math package
NOTE: You may also need to install numpy to get your installation to work. Personally, I used
sudo apt-get install numpysince I didn't know exactly which package caused the install to complain.
Install GCC 4.8
gcc4.8 is required for C++11. You may do this however you like. But here are some instructions for one way of doing it.
** gcc-4.8 is required by NuPIC now ** and it is also default on most Ubuntu systems (14.04 LTS +)
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8 g++-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8
sudo update-alternatives --config gcc(Choose the option for the new 4.8 compiler)
Clone the NuPIC repo
Change to the directory where you want to keep the nupic repo:
git clone https://github.com/numenta/nupic.git
This will create a
nupic directory containing the NuPIC source code in the current directory.
Set the NUPIC environment variable
python setup.py install --user
If you have problems with the
python setup.py install command, try cleaning out your local checkout by running
git clean -dfx. WARNING: This will clear out any local files that are not controlled by git.
Not enough memory for compilation
If you run in VM (or on a system with quite low RAM), for compilation it seems the
gcc requires atleast 2GB RAM memory, otherwise you can see errors like in this thread
