在 Reasoning Engine 上建構、測試及部署自訂應用程式

這個範例示範如何在 Reasoning Engine 上建構、測試及部署自訂應用程式。包括應用程式的本機測試，以及在 Reasoning Engine 上部署應用程式的步驟。

程式碼範例

Python

在試用這個範例之前，請先按照Python使用用戶端程式庫的 Vertex AI 快速入門中的操作說明進行設定。 詳情請參閱 Vertex AI Python API 參考說明文件。

如要向 Vertex AI 進行驗證，請設定應用程式預設憑證。 詳情請參閱「為本機開發環境設定驗證」。

import vertexai
from vertexai.preview import reasoning_engines

# TODO(developer): Update and un-comment below lines
# PROJECT_ID = "your-project-id"
# staging_bucket = "gs://YOUR_BUCKET_NAME"
vertexai.init(
    project=PROJECT_ID, location="us-central1", staging_bucket=staging_bucket
)

class SimpleAdditionApp:
    def query(self, a: int, b: int) -> str:
        """Query the application.
        Args:
            a: The first input number
            b: The second input number
        Returns:
            int: The additional result.
        """
        return f"{int(a)} + {int(b)} is {int(a + b)}"

# Locally test
app = SimpleAdditionApp()
app.query(a=1, b=2)

# Create a remote app with Reasoning Engine.
# This may take 1-2 minutes to finish.
reasoning_engine = reasoning_engines.ReasoningEngine.create(
    SimpleAdditionApp(),
    display_name="Demo Addition App",
    description="A simple demo addition app",
    requirements=["cloudpickle==3"],
    extra_packages=[],
)
# Example response:
# Using bucket YOUR_BUCKET_NAME
# Writing to gs://YOUR_BUCKET_NAME/reasoning_engine/reasoning_engine.pkl
# ...
# ReasoningEngine created. Resource name: projects/123456789/locations/us-central1/reasoningEngines/123456
# To use this ReasoningEngine in another session:
# reasoning_engine = vertexai.preview.reasoning_engines.ReasoningEngine('projects/123456789/locations/...
