# Custom GitHub Actions

Custom actions, written specifically for OpenVINO workflows, are located
in the [actions](../../../../.github/actions) folder along with their source code.

Refer to the official [custom GitHub Action documentation](https://docs.github.com/en/actions/creating-actions/about-custom-actions)
for more information.

## Available Custom Actions

* [Python Setup](#python-setup)
* [System Info Print](#system-info-print)
* Smart CI (see details: [feature documentation](./smart_ci.md))
* OpenVINO Provider (see details: [documentation](./openvino_provider.md))

## Python Setup

This custom action installs the required Python version and environment variables on the runner.
Under the hood it uses the GitHub-provided `actions/setup-python`, and community-provided
`deadsnakes-action`, depending on the machine architecture.
Since `actions/setup-python` does not work on the Linux ARM64 machines,
`deadsnakes-action` is used instead.

### Usage
```yaml
  - name: Setup Python ${{ env.PYTHON_VERSION }}
    uses: ./openvino/.github/actions/setup_python
    with:
      version: '3.11'
      pip-cache-path: ${{ env.PIP_CACHE_PATH }}
      should-setup-pip-paths: 'true'
      self-hosted-runner: 'true'
```
where:
* `version` - the Python version to install in the `MAJOR.MINOR` format
* `pip-cache-path` - the path to the `pip` cache on the mounted share. Read more in the [shares and caches](./caches.md) documentation
* `should-setup-pip-paths` - indicates whether the action should set up the `PIP_CACHE_DIR` and `PIP_INSTALL_PATH` environment variables for later usage
* `self-hosted-runner` - indicates whether the runner is self-hosted. Learn more about [available runners](./runners.md)

## System Info Print

This custom action prints the system information in the standard output:
* Operating system
* Machine architecture
* CPU, RAM, and memory information

Works on Linux, macOS, and Windows.

### Usage
```yaml
  - name: System info
    uses: ./openvino/.github/actions/system_info
```
