If you wish to run jobs on the million-core SpiNNaker machine in Manchester, then we suggest you use our [Jupyter Notebook](/latest/jupyter) instructions, or submit jobs via the [HBP Portal](/latest/hbp_portal) instead. + +# Installation + +You must first install the [Python Dependencies](/common_pages/6.0.0/PythonInstall.html). Continue to the [Virtualenv Installation](#Virtualenv), [Central Installation](#Central), or [User-only Installation](#User) to install the remaining requirements, depending on the needs of your working environment. If you are unsure what to choose, the option that will most likely work is the [Virtualenv Installation](#Virtualenv). + +__Note__: sPyNNakerExternalDevicesPlugin, sPyNNakerExtraModelsPlugin and sPyNNaker8 are no longer required. These extra modules have been merged in to the main sPyNNaker module.

Install pyNN-SpiNNaker: + + python -m spynnaker.setup_pynn + +You can now [configure](#Configuration) 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: + +Run this small script + + import pyNN.spiNNaker as sim + sim.setup() + sim.end() + +Unless one already exists 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: +Warning some systems consider ".spynnaker.cfg" a hidden file. + +``` +[Machine] +machineName = None +version = None +``` + +If you have a SpiNNaker board, then go to [Local Board](#LocalBoard). + +If you do not have a SpiNNaker board, then you have two options: + +1) If you can directly access a local machine that uses spalloc (for example, you are in Manchester and wish to use the million-core machine), then you need to set the following parameters in the ".spynnaker.cfg" you just created (e.g.): + +``` +[Machine] +spalloc_server = spinnaker.cs.man.ac.uk +spalloc_user = user.name@email.address +``` + +where you edit spalloc_server if you are using a different spalloc_server; editing spalloc_user is helpful for administrators of the machine to contact you if there are any problems, which is why we suggest using an email address. + +OR 2) To run in virtual mode, please follow the instructions in [Instructions on how to use the different front ends in virtual mode](/common_pages/6.0.0/VirtualMode.html) and then go to [Running some examples](#Examples). + +## Local Board + +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 IP address for a spinn-3 board is `192.168.240.253` and the default IP address for a spinn-5 board is `192.168.240.1`. + +Now go to [Network Configuration](#NetworkConfiguration). + +## Network Configuration + +Go to the network settings for your computer and add or set an IPv4 entry with the following address for the adapter connected to the SpiNNaker board: + + 1. IP address = `192.168.240.254` + 2. sub-mask = `255.255.255.0` + 3. default gateway = `0.0.0.0` + + +Optional: See [Algorithms](/common_pages/Algorithms.html) for how advanced users change change the algorithms used. + +# Running some examples +1. Download the examples: + + * https://github.com/SpiNNakerManchester/PyNNExamples + +1. Go to the "examples" folder +1. Run: + + python va_benchmark.py + +1. You will see the system go through a series of processes from partitioning, to placement, to routing and finally to loading and running. +1. Once the example has finished, you should see a graph that will look something like this: + + ![VABenchmarkSpikes](vabenchmark8_v6.png) + +If you get the output above, you have successfully installed your system. + +# Troubleshooting + + +1. In OSX, if experiencing the following tkinter error: + + _tkinter.TclError: no display name and no $DISPLAY environment variable + + it may be solved by setting the backend for matplotlib. This can be done by editing the matplotlibrc file in the current working directory to read to ```backend: TkAgg```. This is usually found in `$DEV/lib/pythonXXX/site-packages/matplotlib/mpl-data/matplotlibrc` + + In a virtualenv, create a new file in the root directory ```.matplotlib/matplotlibrc``` that reads ```backend: TkAgg```. ([Sample matplotlibrc file](https://matplotlib.org/_static/matplotlibrc)) + + If you are still having issues, you may also need to install [XQuartz](https://www.xquartz.org/). + +2. In OSX, if you have problems during the installation of the `csa` package (a dependency of sPyNNaker; this problem cascades outwards) within your virtualenv, then use: + + MPLBACKEND=module://matplotlib.backends.backend_agg pip install sPyNNaker --user + + This overrides the matplotlib plotting backend _just during the installation phase,_ which is sufficient to get a working installation if you are not actively using matplotlib to do immediate plotting of the data. + +# Other Links + +Follow [SpiNNaker Extensions](PyNNOnSpiNNakerExtensions.html) to install extensions for building new neuron models. + diff --git a/spynnaker/PyNNOnSpinnakerInstall.md b/spynnaker/PyNNOnSpinnakerInstall.md index cdc6e69..ab41678 100644 --- a/spynnaker/PyNNOnSpinnakerInstall.md +++ b/spynnaker/PyNNOnSpinnakerInstall.md @@ -1,3 +1,3 @@ --- -redirect_to: /spynnaker/6.0.0/PyNNOnSpinnakerInstall.html +redirect_to: /spynnaker/8.0.0/PyNNOnSpinnakerInstall.html --- \ No newline at end of file
