Build the extension
This guide explains how to use the build-extension command to package your Python code into extensions for Altair AI Tools.
Build Command Overview
The build-extension command packages your Python code, configuration files, and environment specifications into a distributable ZIP archive that can be installed in AI Studio.
Basic Usage
build-extension [options] PATH
Where PATH is the directory containing your extension definition and source code.
Command Options
| Option | Description |
|---|---|
-h, --help |
Show the help message and exit |
-f FILE, --file FILE |
Specify the extension configuration file (default: extension.toml) |
-o OUTPUT, --output OUTPUT |
Set the output directory for the built extension |
-c, --compile |
Compile Python files to .pyc format |
--download-env |
Download and include environment packages for offline deployment |
--list-at-root |
List operators at root level in Studio (not within folders) |
-v, --verbose |
Show detailed information during the build process |
Common Build Scenarios
Building for Online Environment (Default)
When users have internet access, you can build a lightweight extension that will download required packages during installation:
On Windows
build-extension -o "%USERPROFILE%\.AltairRapidMiner\AI Studio\shared\extensions\python-extensions" .
On macOS/Linux
build-extension -o "~/.AltairRapidMiner/AI Studio/shared/extensions/python-extensions" .
This creates an extension ZIP file that includes just the environment specification file.
This will create the extension zip file including the environment file in the output directory.
Building for Offline Environment (Air-Gapped)
This downloads all required packages and includes them in the extension ZIP file for offline installation.
build-extension -o "output_directory" -c --download-env .
Compiling Python Files
You can also compile python files to .pyc format by specifying the -c flag in the build-extension command.
Building Process
When you run build-extension, the command:
- Reads your extension configuration from extension.toml
- Validates the extension structure and dependencies
- Creates the environment specification (or downloads packages if requested)
- Packages everything into a ZIP file named after your extension
- Places the ZIP file in the specified output directory
Next Steps
After building your extension, you can:
- Start Altair AI Studio and test the extension.
- Share it with others for installation on their systems
- Update your code and rebuild as needed during development
