LEMS interpreter implemented in Python

PyLEMS

A LEMS (http://lems.github.io/LEMS) simulator written in Python which can be used to run NeuroML2 (http://neuroml.org/neuroml2.php) models.

Installation

A stable version of PyLEMS is available on PyPI using pip:

pip install pylems

To install as root:

sudo pip install pylems

Alternatively, you can obtain the latest version with

git clone https://github.com/LEMS/pylems.git
cd pylems 
git checkout development   # optional
sudo python setup.py install

Usage as a LEMS model simulator

pylems [options] LEMS_file

Options

• -I/-include path - Adds a directory to the model file include search path

LEMS examples (in directory examples)

• example1.xml -- Working
• example2.xml -- Working
• example3.xml -- Working
• example4.xml -- Not working (Unsupported in PyLEMS: KSChannel)
• example5.xml -- Not working (Unsupported in PyLEMS: KSChannel)
• example6.xml -- Working -- TODO: Rest of examples require an update to the <Simulation> element, i.e. use <Simulation...> not <SimulationSet...>, to work in PyLEMS

LEMS elements that do not work

• KSChannel
• Property
• XPath based parameters - PathParameter
• Assertions

Tasks TODO

• Implement flattening
• Decouple events from runnables
• Improve dimension-checking on expressions.
