This project contains research code related to the deployment of inference or learning applications on tiny micro-controllers.
- Free software: Apache License, Version 2.0
- Python Package: https://pypi.org/project/mlonmcu/
- Documentation: https://mlonmcu.readthedocs.io or https://tum-ei-eda.github.io/mlonmcu/
- Highly configurable python package
- Automatic resolution and installation of dependencies
- Supporting a large combination of frameworks/backends/targets/features
- Build-in parallel processing of large number of benchmarks
- Isolated enironments (not interfering with other installations)
- Command Line and Python Development Interfaces
- Docker images to get started quickly
- Extensive documentation on usage and code details
- CI/CD integration and high PyTest coverage
First, a set of APT packages needs to be installed:
# Python related
sudo apt install python3-pip python3-venv
# MLonMCU related
sudo apt install libboost-all-dev graphviz doxygen libtinfo-dev zlib1g-dev texinfo unzip device-tree-compiler tree g++
# Optional (depending on configuration)
sudo apt install ninja-build
Also make sure that your default Python is at least v3.7. If the python
command is not available in your shell or points Python v2.7 check out python-is-python3
.
Warning: It seems like the ETISS tool fails to compile if if find a version of LLVM 11 on your system which does not include Clang 11. The best workaround for now is to (if possible) remove those tools from your system: sudo apt remove llvm-11* clang-11*
(See issue #1)
Make sure to use a fresh virtual Python environment in the following steps.
Warning: As the PyPI package is not always up to date, it is currently recommented to use a self-build version of the package (as explained in the next section)
To use the PIP package, run the following: pip install mlonmcu
(Add --user
if you are not using a virtual environment)
First, install all relevant dependencies:
python -m venv .venv # Feel free to choose a different directory or use a conda environment
# Run this whenever your have updated the repository
source .venv/bin/activate
# Environment-specific dependencies are installed later
**Warning:** It is recommended to have at least version 3.20 of CMake installed for full compatibility!
# Install ptional dependecies (only for development)
pip install -r requirements_dev.txt
pip install -r docs/requirements.txt
# Only if you want to use the provided python notebooks, as explained in ./ipynb/README.md
pip install -r ipynb/requirements.txt
Then you should be able to install the mlonmcu
python package like this
# Optionally remove an older version first: pip uninstall mlonmcu
make install # Alternative: python setup.py install
See ./docker/README.md
for more details.
This repository ships three different types of docker images based on Debian:
-
A minimal one with preinstalled software dependencies and python packages
Feel free to use this one if you do not want to install anything (except Docker) on your main sytem to work with mlonmcu
-
A medium one which already has the
mlonmcu
python package installedRecommended and the easiest to use. (Especially when using
docker-compose
to mount shared directories etc.) -
A very large one with an already initialized and installed
Mainly used for triggering automated benchmarks without spending too much time on downloading/compiling heavy dependencies over and over again.
Is is recommended to checkout the provided Demo Jupyter Notebook as it contains a end-to-end example which should help to understand the main concepts and methodology of the tool. The following paragraphs can be seen as a TL;DL version of the information in that Demo notebook.
While some tools and features of this project work out of the box, some of them require setting up an environment where additional dependencies are installed. This can be achived by creating a MLonMCU environment as follows:
mlonmcu init
Make sure to point the MLONMCU_HOME
environment variable to the location of the previously initialied environment. (Alternative: use the default
environment or --home
argument on the command line)
Next, generate a requirements_addition.txt
file inside the environment directory using mlonmcu setup -g
which now be installed by running pip install -r $MLONMCU_HOME/requirements_addition.txt
inside the virtual Python environment.
To use the created environment in a python program, a MlonMcuContext
needs to be created as follows:
import mlonmcu.context
with mlonmcu.context.MlonMcuContext() as context:
pass
Make sure to first install the additonal set of development Python packages into your virtual environment:
pip install -r requirements_all.txt # Install packages for every component (instead of using mlonmcu setup -g)
pip install -r requirements_dev.txt # Building distributions and running tests
pip install -r docs/requirements.txt # For working with the documentation
Unit test and integration test are defined in the tests/
directory and can be triggered using make test
or pytest tests/
Coverage can be determined by running make coverage
. The latest coverage report (HTML) for the default branch can also be found as an artifact of the CI/CD workflow.
Documentation is mainly generated automatically from doctrings (triggered via make html
). It is also possible to include markdown files from the repo into the .rst
files found in the docs/
directory. There is a GitHub workflow which publishes the documentation for the default branch to our GitHub Pages.
Regarding coding style, it is recommended to run black
before every commit. The default line length should be given in the setup.cfg
file.
This is a research project proposed by the Chair of Design Automation of the Technical University of Munich.

This package was created with Cookiecutter_ and the audreyr/cookiecutter-pypackage
_ project template. However most of the templates was manually changed to be in Markdown instead of reStructuredText.
