Virtualenv git clone

These instructions will install the required packages only in a virtualenv. Like the user-only installation, this can help when you don’t have root access or are on a shared machine. Additionally, it will help when you have several packages with conflicting dependencies, or those that occupy the same namespace (such as pyNN.spiNNaker if you have an older version of the toolchain).

If you already have installed sPyNNaker previously (and the optional sPyNNakerExtraDevicesPlugin and/or sPyNNakerExtraModelsPlugin), you will need to uninstall it:

  1. Activate your virtualenv, <name> source <name>/bin/activate
  2. Uninstall the existing tools pip uninstall pyNN-SpiNNaker pip uninstall sPyNNaker pip uninstall sPyNNakerExternalDevicesPlugin pip uninstall sPyNNakerExtraModelsPlugin

The installation of virtualenv and the linking to the external libraries is platform dependent.

Continue to the C Compiler Install to install the remaining c compiler dependency

C Development Environment

  1. Primarily, you will need to install a C compiler that is compatible with SpiNNaker. At present, we recommend using gcc for this. Instructions for installing this on your system are below, depending on which platform you are using, as well as instructions for installing Perl, which is used by the development tools to modify the generated binaries to run on SpiNNaker:

Development Dependencies for 64-bit Ubuntu

  1. Install 32-bit libc sudo apt-get install libc6-i386
  2. Install perl and dependencies sudo apt-get install perl perl-tk libterm-readline-gnu-perl
  3. Follow the instructions for the Linux C Compiler

Development Dependencies for 64-bit Fedora

  1. Install 32-bit libc sudo dnf install glibc.i686
  2. Install perl and dependencies sudo dnf install perl perl-Tk perl-Term-ReadLine-Gnu
  3. Follow the instructions for the Linux C Compiler

Development Dependencies for 32-bit Ubuntu

  1. Install perl and dependencies sudo apt-get install perl perl-tk libterm-readline-gnu-perl
  2. Follow the instructions for the Linux C Compiler

Development Dependencies for 32-bit Fedora

  1. Install perl and dependencies sudo dnf install perl perl-Tk perl-Term-ReadLine-Gnu
  2. Follow the instructions for the Linux C Compiler

Linux C Compiler

  1. Download CodeSourcery GCC ARM EABI Compiler
  2. Extract the downloaded archive to the location of your choice
  3. Add the “bin” directory within the installed location to the PATH enviroment variable in .profile in your home directory e.g. append the following: export PATH=$PATH:<install-location>/bin
    where <install-location> is the place where you extracted the file.

Development Dependencies for Mac OS X

  1. Install the arm-none-eabi toolchain sudo port install arm-none-eabi-gcc
  2. Install perl and dependencies sudo port install perl5 p5-tk p5-term-readline-gnu
  3. Optional: Install Xcode and all its development tools from here NOTE: take into account your Mac version.

Development Dependencies for Windows

  1. Download the prepackaged MinGW Environment
  2. Extract the downloaded archive to the location of your choice
  3. Create a shortcut to MinGW/msys/1.0/msys.bat and add it to your start menu

You can now use the msys.bat to start up an environment from in which you can compile C code for SpiNNaker.

SpiNNakerTools Installation

  1. Create an environment variable SPINN_DIRS that points at the location of the cloned https://github.com/SpiNNakerManchester/spinnaker_tools.git (note that in Windows, this should be the MinGW Posix path e.g. if you have extracted the archive to C:\SpiNNaker-Tools\, you should set the environment variable to /c/SpiNNaker-Tools).
  2. Run make in the root directory of the extracted archive.

spinn_common Library Installation

The spinn_common library will be installed into the SpiNNaker Tools installation directory, as set up above.

  1. In the directory of the cloned https://github.com/SpiNNakerManchester/spinn_common.git, run make.
  2. Run make install.

SpiNNFrontEndCommon Library Installation

The SpiNNFrontEndCommon library will be installed into the SpiNNaker Tools installation directory, as set up above.

  1. In the c_common directory of the cloned https://github.com/SpiNNakerManchester/SpiNNFrontEndCommon.git, run make.
  2. Run make install.

YBug Installation

If you want to avoid having to run “source setup” in the ybug folder every time you log in or start a new terminal:

  1. Add the cloned ybug folder to your PATH environment variable
  2. Add the cloned ybug folder to your PERL5LIB environment variable (or create this environment variable if it is not already set; note that in Windows, this should be the MinGW Posix path e.g. if you have extracted the archive to C:\ybug\, you should set the environment variable to /c/ybug)
  3. If you are going to boot your board using ybug, create a new environment variable YBUG_PATH and set this to the boot subdirectory of the extracted ybug folder.

To run ybug:

  1. If you haven’t added the environment variables detailed above, go into the directory where you extracted the archive and run: source setup
  2. Run: ybug <ip-or-host>
    where <ip-or-host> is the ip address or hostname of your SpiNNaker board.
  3. Type help to get further usage instructions.

  4. Continue to the Compile Binaries to compelte the installation by compiling the binaries of the c code used by the tool chain.

Compile Binaries

To compile the c code used by the tool chain, run the following instructions from the base folder where all the software is installed:

cd spinnaker_tools
source setup
cd ..
cd spinn_common
make clean
make 
make install
cd ..
cd SpiNNMan/c_models/reinjector/
make 
cd ../../..
cd SpiNNFrontEndCommon/c_common/front_end_common_lib/
make install-clean
cd ..
make clean
make 
make install
cd ../..
cd sPyNNaker/neural_modelling/
make clean
make 
source setup
cd ../../SpiNNakerGraphFrontEnd/examples/
make clean
make 

Continue to configure your environment.

Configuration

When SpyNNaker is first called, if a configuration file is not found, it will create one in your home directory and exit. It is possible to ask SpyNNaker to do this before you run your first simulation as follows: python -c "import pyNN.spiNNaker"

Note that if you have previously installed a version of the spiNNaker software, you may already have a file called “.pacman.cfg” in your home directory. In this case, SpyNNaker will attempt to use this file for its paramters. If you don’t have this file, a new file called “.spynnaker.cfg” will be created in your home directory. You must edit this file to ensure that SpyNNaker can access your SpiNNaker machine. Upon opening this file, the part to alter will look like the following: [Machine] machineName = None version = None

Within the file, you should set machineName to the IP address or hostname of your SpiNNaker machine, and version to the version of your SpiNNaker board; this will almost certainly be “3” for a 4-chip board or “5” on a 48-chip board.

The default ipaddress for a spinn-3 board is 192.168.240.253 and the default ipaddress for a spinn-5 board is 192.168.240.1

Network Configuration

Go to your network settings and set up your network adapter with the following settings:
1. ipaddress = 192.168.240.254 2. submask = 255.255.255.0 3. default gateway = 0.0.0.0

Running some examples

  1. Download the examples from here (zip) or here (tar.gz)
  2. Extract the archive
  3. Go to the “examples” folder
  4. Run: python va_benchmark.py
  5. You will see the system go through a series of processes from partitioning, to placement, to routing and finally to loading and running.
  6. Once the example has finished, you should see a graph, that will look something like this:
    VABenchmarkSpikes If you get the output above, you have successfully installed your system.

Troubleshooting

  1. If you experience the error:

**UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 1: ordinal not in range(128)**

Then to solve it, edit C:\Python27\Lib\mimetypes.py and add these codes:

if sys.getdefaultencoding() != 'gbk':  
    reload(sys)
    sys.setdefaultencoding('gbk')

before the following line:

default_encoding = sys.getdefaultencoding()
