Description

The input and output of the AI model are defined in my_ai_lib/run.py.
The AI model is designed to process a single input item.
In my_ai_lib/predict_submission.py, we process all items in the test dataset and save the results to result.csv in the required submission format.
Please refer to the instructions below for more details.

Key Components

Component	Description	Status
`my_ai_lib/`	Core AI library directory	Required
`my_ai_lib/__init__.py`	Library initialization	Required
`my_ai_lib/predict_submission.py`	Generate predictions for challenge submission.	Required
`my_ai_lib/run.py`	Main AI workflow	Required
`demo.py`	Demo and testing script	Required

Detailed Tutorial

Step 1: Initialize Your AI Library

1.1 Define `my_ai_lib/init.py`

from .run import run

This file defines that the run() function in run.py as an attribute of the my_ai_lib and that I can call it by my_ai_lib.run()

1.2 Define Input/Output Objects in `my_ai_lib/run.py`

Create your custom input and output classes:

from pathlib import Path
from typing import Any, Union, Literal
from aioz_ainode_adapter.schemas import InputObject, OutputObject, FileObject

class MyInput(InputObject):
    input_text: str

class MyOutput(OutputObject):
    text: str

Step 2: Understanding AIOZ Schema Objects

The aioz_ainode_adapter library defines 3 core object types based on pydantic.BaseModel:

🔸 InputObject

Define the format for input when the AIOZ-AI-Node system sends to your AI library.

Default Parameters:

Parameter	Type	Description
`device`	Choice	Device for your model: `["cuda", "cpu"]`
`model_storage_directory`	String	Directory containing model weights

Important : Always use model_storage_directory for model weight paths, as AIOZ-AI-Node will specify this location.

🔸 OutputObject

Define the format for output when your AI library sends to the AIOZ-AI-Node system.

🔸 FileObject

Define the format for the file, if your output has a file. This object has two fields:

Field	Type	Description
`data`	Choice	File data: `io.BufferedReader`, `Path`, or `URL`
`name`	String	File name

Example FileObject creation:

output_file = FileObject(data=open("file/path.csv", "rb"), name="output.csv")

Note:

If your input param have a file, it must be a local file path or URL

If your output has a file, it must be a FileObject

Step 3: Implement the Main Workflow

3.1 Define Your AI Task Function

def do_ai_task(
        input_text: Union[str, Path],
        model_storage_directory: Union[str, Path],
        device: Literal["cpu", "cuda", "gpu"] = "cpu",
        *args, **kwargs) -> Any:
    """Define AI task: load model, pre-process, post-process, etc ..."""
    # Define AI task workflow. Below is an example
    text = model.predict(input_text) #input_text: features, text is price
    return text

3.2 Implement the Required `run()` Function

def run(input_obj: InputObject) -> OutputObject:
    """
    Main entry point for your AI library.
    
    Args:
        input_obj: Input object containing all parameters
        
    Returns:
        OutputObject: Results of AI processing
    """
    try:
        # Validate and parse input
        my_input = MyInput.model_validate(input_obj.model_dump())
        print(f"Input: {my_input}")

        # Execute AI task
        text = do_ai_task(
            input_image=my_input.input_text,
            model_storage_directory=my_input.model_storage_directory,
            device=my_input.device
        )
        # Create output object
        output_obj = MyOutput(text=text)
    except Exception as e:
        raise Exception(e)

    return output_obj

Critical: The run() function name is mandatory and cannot be changed. The do_ai_task() function can be renamed and customized.

Step 4: Create Demo Script

Create demo.py to test your implementation:

import my_ai_lib
from aioz_ainode_adapter.schemas import InputObject


def main():
    """Demo function to test your AI library."""
    input_obj = InputObject(
        input_image="wiki/aioz.png", 
        example_param="example"
    )
    output_obj = my_ai_lib.run(input_obj)
    print(f"Output: {output_obj}")


if __name__ == '__main__':
    main()

The my_ai_lib.run() function receives an InputObject and returns an OutputObject.

Run this command to test your implementation:

python demo.py

Expected console output:

Input: type='InputObj' device='cuda' model_storage_directory='models' input_image='wiki/aioz.png' example_param='example'
Output: type='OutputObj' text='This is the AI task result' output_image=FileObject(type='FileObj', data=<_io.BufferedReader name='wiki/aioz.png'>, name='output_image.png')

Step 5: Add Model Weights

Place your trained model files in the models/ directory:

models/
├── model.pth          # Your trained model
├── config.json        # Model configuration
└── etc.

Step 6: Create Prediction Script (For Submission)

Implement the predict_submission() function in my_ai_lib/predict_submission.py:

Requirements:

Function accepting test data folder path (string)
Load your trained model
Process test dataset (test.csv in test data folder)
Generate predictions
Save results as ./result.csv

Implementation Template:

from aioz_ainode_adapter.schemas import InputObject
import my_ai_lib

def predict_submission(test_data_folder: str):
    """
    Generate predictions for challenge submission.
    
    Args:
        test_data_folder: Path to test data directory
    """
    # Load your model
    # Process test data
    # Generate predictions
    # Save to ./result.csv

    # Example:
    # Find test data (test.csv) in test data folder (using os.walk)
    # Loop with each feature (of a house):
    # - You define InputObject
    #     input_obj = InputObject(
    #     input_text=str(feature), 
    # )
    # - Output (price is predicted from your model): output = my_ai_lib.run(input_obj)
    # - Write the predicted price (output.text) to result.csv
    pass

def main():
    """Main function for testing submission."""
    predict_submission("path/to/test/data")

if __name__ == '__main__':
    main()

Important: The result.csv must match the challenge's sample submission format.

Verify Your Submission:

python -m my_ai_lib.predict_submission

Submission Guidelines

Submission format

The submission file has two field:

house_index: The unique identifier/index corresponding to house.
price: The predicted price for the corresponding house.

Example:

house_index, price
123,12345
124,54321
