Installing NuPIC on OS X Mavericks †

Overview †

This article briefly explains what NuPIC is and shows how to install NuPIC on OS X Mavericks.

NuPIC is an algorithm for machine learning, based upon CLA/HTM Theory. This is developed by Numenta. This is not the newest version of Numenta's machine learning algorithm, but this is freely available at GitHub.

More information and a copy of NuPIC are available at NuPIC WiKi

For details of how to install and how to execute NuPIC on OS X Mavericks, please visit the article at GitHub:Running NuPIC on OS X.

Instructions for building NuPIC †

1. Checking OS
The minimum version of OS X is 10.9. If you are using older than OS X 10.9 Mavericks, please update your OS X. This article uses OS X 10.9.2.

2 Setting up Build Tools
Install Xcode from App Store. Then, install Command Line Tools from the inside of Xcode.

Xcode > Open Developer Tool > More Developer Tools

Or, opening up Terminal, apply the command below

xcode-select –install

3. Installing homebrew
homebrew is a package installer. To use homebrew, install the software packages listed below.

• automake
• libtool
• cmake

Cmake can be installed from the dmg file, which can be downloaded the wehis article uses the homebrew.

$ brew update
$ brew doctor

If there are no problems on the installation of homebrew, install the packages listed above.

$ brew install automake libtool cmake

4. Downloading source code of NuPIC
Check out source code from git. If you wish to contribute your modified code to the project of NuPIC, you will need your own git account.

$ cd ~
$ mkdir work
$ cd work
$ git clone https://github.com/numenta/nupic.git

5. Configuring environment variable
To set up the environment variable, which is required for building and executing NuPIC, record the information of PATH and others on .profile file.
Usually this file is set to be invisible. Please use Terminal to find this file.

~/.profile

Configure environment variables, which are needed for building and executing NuPIC. Open up .profile, and write down the information shown below.

# The directory of source repository where it is  git checkout 
export NUPIC=~/work/nupic
# Installation PATH of NTA
export NTA=$NUPIC/nta/eng
# Temporary Build file PATH
export BUILDDIR=/tmp/ntabuild
# Number of concurrent jobs for building (i.e. number of CPU cores + 1)
export MK_JOBS=3
# Configuration for other required environment variables
source $NUPIC/env.sh

Then, go back to Terminal, open up .profile file, and make sure the information above is written correctly.

$ printenv 

6. Installing pip
Installing pip, which is a package manager for Python.

$ sudo easy_install pip

7. Installing Python libraries
Using pip, install Python libraries, which are required for NuPIC.

$ sudo pip install -r $NUPIC/external/common/requirements.txt

If you use pip 1.5 or later, you may apply the command line below.~

$ sudo pip install --allow-all-external --allow-unverified PILL --allow-unverified psutil -r $NUPIC/external/common/requirements.txt

If you encounter a permission denied error when you use pip, please run pip with sudo. For farther details of the error, please visit this page.

8. Building and Installing NuPIC

Move to the NuPIC installation directory and execute the command below.~
Python setup.py install

If you can see the message listed below, the installation of NuPIC is successful.

$ $NUPIC/build.sh
...
...
...
Stdout redirected to; /Users/otsuka/work/nupic/build_system/stdout.txt
Build successful.

If you face a permission denied error when you use NuPIC, please execute NuPIC with sudo. Please go to this page for more information.

Test †

Please test that NuPIC can be executed properly when it is successfully built and installed.
