The purpose of this repository

  • I'll verify the HTM using the task of ImageNet LSVRC-2014.


  • Dataset
  • Install nupic/pylearn2
  • Simple task



  • The CIFAR-10 dataset consists of 60000 32x32 colour images in 10 classes, with 6000 images per class.
  • The CIFAR-10 dataset

ImageNet Classification with Deep Convolutional Neural Networks


Numenta Platform for Intelligent Computing

Numenta Platform for Intelligent Computing: a brain-inspired machine intelligence platform, and biologically accurate neural network based on cortical learning algorithms. 
The Numenta Platform for Intelligent Computing (NuPIC) is a machine intelligence platform that implements the HTM learning algorithms. HTM is a detailed computational theory of the neocortex. At the core of HTM are time-based continuous learning algorithms that store and recall spatial and temporal patterns. NuPIC is suited to a variety of problems, particularly anomaly detection and prediction of streaming data sources.
For more information, see or the NuPIC wiki.

Installing NuPIC 0.5.4

NuPIC binaries are available for:
  • Linux x86 64bit
  • OS X 10.9
  • OS X 10.10
  • Windows 64bit


The following dependencies are required to install NuPIC on all operating systems.

Install OS X

First, you must install Xcode command line tools, which will get you a C++ compiler.
pip install nupic

Install Linux

NOTE: The nupic.bindings binary distribution is not stored on PyPi along with the OS X distribution. NuPIC uses the wheel binary format, and PyPi does not support hosting Linux wheel files. So we are forced to host our own.
pip install
pip install nupic

Install Windows

pip install nupic
For problems installing NuPIC, please see our Installation and Build Wiki.

Having problems?

  • You may need to use the --user flag for the commands above to install in a non-system location (depends on your environment). Alternatively, you can execute the pip commands with sudo (not recommended).
  • You may need to add the --use-wheel option if you have an older pip version (wheels are now the default binary package format for pip).
For any other installation issues, please see our FAQ, email the nupic-discuss mailing list, or chat with us on Gitter.
