PolarisAIDataInsightLoader 集成

使用 LangChain Python 集成 PolarisAIDataInsightLoader 文档加载器。

Polaris AI DataInsight is a document parser that extracts document elements (text, images, complex tables, charts, etc.) from various file formats into structured JSON, making them easy to integrate into RAG systems.

安装

安装 langchain-polaris-ai-datainsight package。

pip install langchain-polaris-ai-datainsight

Environment setup

确保设置以下环境变量：

• POLARIS_AI_DATA_INSIGHT_API_KEY: Your Polaris AI DataInsight API key. Read Polaris AI DataInsight Documentation to get your API key.

用法

import getpass
import os

os.environ["POLARIS_AI_DATA_INSIGHT_API_KEY"] = getpass.getpass(
    "Enter your PolarisAIDataInsight API key: "
)

from langchain_polaris_ai_datainsight import PolarisAIDataInsightLoader

loader = PolarisAIDataInsightLoader(
    file_path="example_data/polaris_ai_example.docx",
    resources_dir="example_data/tmp",
    mode="page",  # "element", "page", or "single". (default is "single")
)

docs = loader.load()  # or loader.lazy_load()

for doc in docs[:3]:
    print(" --------- < Page Content > --------- ")
    print(doc.page_content)
    print(" --------- < Metadata > --------- ")
    print(doc.metadata)
    print("\n")

Then, you will see the extracted content and metadata from the document as below:
