The Golem Network fosters a global group of creators building ambitious software solutions that will shape the technological landscape of future generations by accessing computing resources across the platform. Golem Network is an accessible, reliable, open access and censorship-resistant protocol, democratizing access to digital resources and connecting users through a flexible, open-source platform.
Yapapi is the Python high-level API that allows developers to connect to their Golem nodes and manage their distributed, computational loads through Golem Network.
For a detailed introduction to using Golem and yapapi to run your tasks on Golem and a guide to Golem Network application development in general, please consult our handbook.
yapapi is available as a PyPI package.
You can install it through pip:
pip install yapapiOr if your project uses poetry you can add it to your dependencies like this:
poetry add yapapiFor a comprehensive API reference, please refer to our official readthedocs page.
yapapi uses poetry to manage its dependencies and provide a runner for common tasks.
If you don't have poetry available on your system then follow its installation instructions before proceeding.
Verify your installation by running:
poetry --versionTo install the project's dependencies run:
poetry installBy default, poetry looks for the required Python version on your PATH and creates a virtual environment for the project if there's none active (or already configured by Poetry).
All of the project's dependencies will be installed to that virtual environment.
yapapi uses Poe the Poet for running tasks.
Declarations of project tasks can be found in pyproject.toml.
poetry run poe tests_unitIf you'd like to run the yapapi integration test suite locally then you'll need to install an additional set of dependencies separately.
First, install the dependencies required to run goth.
Next, configure goth's GitHub API token.
Make sure you have OpenSSH installed and added to path
ssh -VNow, you can install goth and its additional python requirements:
poetry install -E integration-testsFinally, generate goth's default assets:
poetry run poe tests_integration_assetsOnce you have the environment set up, to run all the integration tests, use:
poetry run poe tests_integrationIt is recommended to run unit tests and static code analysis before committing changes.
poetry run poe checksYou can clean up the artifacts created during the test runs with:
poetry run poe clean- Golem, a global, open-source, decentralized supercomputer that anyone can access.

It's possible to set various elements of yagna configuration through environment variables.
yapapi currently supports the following environment variables:
YAGNA_ACTIVITY_URL, URL toyagnaactivity API, e.g.http://localhost:7500/activity-api/v1YAGNA_API_URL, base URL toyagnaREST API, e.g.http://localhost:7500YAGNA_APPKEY,yagnaapp key to be used, e.g.a70facb9501d4528a77f25574ab0f12bYAGNA_MARKET_URL, URL toyagnamarket API, e.g.http://localhost:7500/market-api/v1YAGNA_PAYMENT_NETWORK, Ethereum network name foryagnato use, e.g.rinkebyYAGNA_PAYMENT_DRIVER, payment driver name foryagnato use, e.g.erc20YAGNA_PAYMENT_URL, URL toyagnapayment API, e.g.http://localhost:7500/payment-api/v1YAGNA_NET_URL, URL toyagnanet APU, e.g.http://localhost:7500/net-api/v1YAGNA_SUBNET, name of theyagnasub network to be used, e.g.publicYAPAPI_USE_GFTP_CLOSE, if set to a truthy value (e.g. "1", "Y", "True", "on") thenyapapiwill askgftpto close files when there's no need to publish them any longer. This may greatly reduce the number of files kept open whileyapapiis running but requiresyagna0.7.3 or newer, with older versions it will cause errors.
