Azure 認知服務工具組

此工具組用於與 Azure Cognitive Services API 互動，以實現一些多模態功能。

目前此工具組中包含四個工具

  • AzureCogsImageAnalysisTool：用於從圖像中提取標題、物件、標籤和文本。（注意：由於依賴於 azure-ai-vision 套件，此工具目前在 Mac OS 上不可用，該套件目前僅在 Windows 和 Linux 上受支援。）
  • AzureCogsFormRecognizerTool：用於從文件中提取文字、表格和鍵值對。
  • AzureCogsSpeech2TextTool：用於將語音轉錄為文字。
  • AzureCogsText2SpeechTool：用於將文字合成語音。
  • AzureCogsTextAnalyticsHealthTool：用於提取醫療保健實體。

首先，您需要設定一個 Azure 帳戶並建立一個 Cognitive Services 資源。您可以按照此處的指示建立資源。

然後，您需要取得資源的端點、金鑰和區域，並將它們設定為環境變數。您可以在資源的「金鑰和端點」頁面中找到它們。

%pip install --upgrade --quiet  azure-ai-formrecognizer > /dev/null

import os

os.environ["OPENAI_API_KEY"] = "sk-"
os.environ["AZURE_COGS_KEY"] = ""
os.environ["AZURE_COGS_ENDPOINT"] = ""
os.environ["AZURE_COGS_REGION"] = ""

建立工具組​

from langchain_community.agent_toolkits import AzureCognitiveServicesToolkit

toolkit = AzureCognitiveServicesToolkit()
[tool.name for tool in toolkit.get_tools()]
['Azure Cognitive Services Image Analysis',
 'Azure Cognitive Services Form Recognizer',
 'Azure Cognitive Services Speech2Text',
 'Azure Cognitive Services Text2Speech']

在 Agent 中使用​

from langchain.agents import AgentType, initialize_agent
from langchain_openai import OpenAI
llm = OpenAI(temperature=0)
agent = initialize_agent(
    tools=toolkit.get_tools(),
    llm=llm,
    agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
)
agent.run(
    "What can I make with these ingredients?"
    "https://images.openai.com/blob/9ad5a2ab-041f-475f-ad6a-b51899c50182/ingredients.png"
