openreview-py

OpenReview Python library

Prerequisites

Python 3.9 or newer is required to use openreview-py.

Installation

There are two ways to install the OpenReview python library.

Using pip:

pip install openreview-py

From the repository:

git clone https://github.com/openreview/openreview-py.git
cd openreview-py
pip install -e .

Note: Depending on your Python installation you may need to use the command pip3 instead of pip.

Production / CI Installation

For reproducible deployments, install the package using the pinned lock file as constraints:

pip install -c requirements.txt .

For development (editable install with pinned dependencies):

pip install -c requirements.txt -e .

Updating Dependencies

This project uses pip-tools to manage dependency versions. pyproject.toml declares compatible version ranges, while requirements.txt (production) and requirements-dev.txt (test + docs) contain the exact pinned versions.

To update all dependencies to the latest compatible versions:

pip-compile pyproject.toml -o requirements.txt --strip-extras
pip-compile pyproject.toml --extra test --extra docs -o requirements-dev.txt --strip-extras

To update a single package:

pip-compile --upgrade-package requests pyproject.toml -o requirements.txt --strip-extras

Note: pip-compile resolves for the Python version of the running interpreter, so the numpy pin in the generated lock files will only match that version. After running pip-compile, manually replace the numpy line in both lock files with environment-marked entries:

numpy==2.0.2 ; python_version < '3.10'
numpy==2.2.6 ; python_version == '3.10'
numpy==2.4.3 ; python_version >= '3.11'

Usage

The openreview-py library can be used to easily access and modify any data stored in the OpenReview system.

For more information, see the official reference. You can also check the OpenReview docs for examples and How-To Guides

Test Setup

Running the openreview-py test suite requires some initial setup. First, the OpenReview API V1, OpenReview API V2 and OpenReview Web frontend must be cloned and configured to run on ports 3000, 3001 and 3030 respectively. For more information on how to install and configure those services see the README for each project:

• OpenReview API V1
• OpenReview API V2
• OpenReview Web

Next, install the package with test dependencies:

pip install -e ".[test]"

Finally, you must download the proper Firefox Selenium driver for your OS from GitHub, and place the geckodriver executable in the directory openreview-py/tests/drivers. When you are done your folder structure should look like this:

├── openreview-py
│   ├── tests
│   │   ├── data
│   │   ├── drivers
│   │   │    └── geckodriver

Run Tests

Once the test setup above is complete you should be ready to run the test suite. To do so, start both OpenReview API versions running:

Inside the OpenReview API V1 directory

npm run cleanStart

Inside the OpenReview API V2 directory

npm run cleanStart

Inside the OpenReview Web directory

SUPER_USER=openreview.net npm run dev

Once all three services are running, start the tests:

pytest

Note: If you have previously set environment variables with your OpenReview credentials, make sure to clear them before running the tests: unset OPENREVIEW_USERNAME && unset OPENREVIEW_PASSWORD

To run a single set of tests from a file, you can include the file name as an argument. For example:

pytest tests/test_double_blind_conference.py
