—A framework for reproducible, comparable benchmarks—

Benchopt is a benchmarking suite tailored for machine learning workflows. It is built for simplicity, transparency, and reproducibility. It is implemented in Python but can run algorithms written in many programming languages.

So far, benchopt has been tested with Python <https://www.python.org/>, R <https://www.r-project.org/>, Julia <https://julialang.org/>_ and C/C++ <https://isocpp.org/>_ (compiled binaries with a command line interface). Programs available via conda <https://docs.conda.io/en/latest/>_ should be compatible as well. See for instance an example of usage <https://benchopt.github.io/stable/auto_examples/plot_run_benchmark_python_R.html>_ with R.

Install

It is recommended to use benchopt within a conda environment to fully-benefit from benchopt Command Line Interface (CLI).

To install benchopt, start by creating a new conda environment and then activate it

.. code-block:: bash

conda create -n benchopt python
conda activate benchopt

Then run the following command to install the latest release of benchopt

.. code-block:: bash

pip install -U benchopt

It is also possible to use the latest development version. To do so, run instead

.. code-block:: bash

pip install git+https://github.com/benchopt/benchopt.git

Getting started

After installing benchopt, you can

replicate/modify an existing benchmark
create your own benchmark

Using an existing benchmark ^^^^^^^^^^^^^^^^^^^^^^^^^^^

Replicating an existing benchmark is simple. Here is how to do so for the L2-logistic Regression benchmark <https://github.com/benchopt/benchmark_logreg_l2>_.

Clone the benchmark repository and cd to it

.. code-block:: bash

git clone https://github.com/benchopt/benchmark_logreg_l2 cd benchmark_logreg_l2

Install the desired solvers automatically with benchopt

.. code-block:: bash

benchopt install . -s lightning -s sklearn

Run the benchmark to get the figure below

.. code-block:: bash

benchopt run . --config ./example_config.yml

.. figure:: https://benchopt.github.io/_images/sphx_glr_plot_run_benchmark_001.png :target: how.html :align: center :width: 60%

These steps illustrate how to reproduce the L2-logistic Regression benchmark <https://github.com/benchopt/benchmark_logreg_l2>. Find the complete list of the Available benchmarks. Also, refer to the documentation <https://benchopt.github.io/>_ to learn more about benchopt CLI and its features. You can also easily extend this benchmark by adding a dataset, solver or metric. Learn that and more in the Benchmark workflow <https://benchopt.github.io/stable/benchmark_workflow/index.html>_.

Creating a benchmark ^^^^^^^^^^^^^^^^^^^^

The section Write a benchmark <https://benchopt.github.io/stable/benchmark_workflow/write_benchmark.html>_ of the documentation provides a tutorial for creating a benchmark. The benchopt community also maintains a template benchmark <https://github.com/benchopt/template_benchmark>_ to quickly and easily start a new benchmark.

Finding help

Join benchopt discord server <https://discord.gg/EA2HGQb7nv>_ and get in touch with the community! Feel free to drop us a message to get help with running/constructing benchmarks or (why not) discuss new features to be added and future development directions that benchopt should take.
