# llama_index 配置文件示例(config.yml) app: name: "llama_index" debug: false log_level: "INFO" # 运行时指定配置文件 llama_index --config config.yml # 或通过环境变量配置 export LLAMA_INDEX_API_KEY="your-key" export LLAMA_INDEX_OUTPUT_DIR="./output"
LlamaIndex OSS (by LlamaIndex) is an open-source framework to build agentic applications. Parse is our enterprise platform for agentic OCR, parsing, extraction, indexing and more. You can use LlamaParse with this framework or on its own; see LlamaParse below for signup and product links.
### 📚 Documentation: - LlamaParse - LlamaIndex OSS - LlamaAgents
Building with LlamaIndex typically involves working with LlamaIndex core and a chosen set of integrations (or plugins). There are two ways to start building with LlamaIndex in Python:
llama-index. A starter Python package that includes core LlamaIndex as well as a selection of integrations.2. Customized: llama-index-core. Install core LlamaIndex and add your chosen LlamaIndex integration packages on LlamaHub that are required for your application. There are over 300 LlamaIndex integration packages that work seamlessly with core, allowing you to build with your preferred LLM, embedding, and vector store providers.
The LlamaIndex Python library is namespaced such that import statements which include core imply that the core package is being used. In contrast, those statements without core imply that an integration package is being used.
```python
NOTE: This README is not updated as frequently as the documentation. Please check out the documentation above for the latest updates!
storage_context = StorageContext.from_defaults(persist_dir="./storage")
By default, llama-index-core includes a _static folder that contains the nltk and tiktoken cache that is included with the package installation. This ensures that you can easily run llama-index in environments with restrictive disk access permissions at runtime.
To verify that these files are safe and valid, we use the github attest-build-provenance action. This action will verify that the files in the _static folder are the same as the files in the llama-index-core/llama_index/core/_static folder.
To verify this, you can run the following script (pointing to your installed package):
#!/bin/bash
STATIC_DIR="venv/lib/python3.13/site-packages/llama_index/core/_static"
REPO="run-llama/llama_index"
find "$STATIC_DIR" -type f | while read -r file; do
echo "Verifying: $file"
gh attestation verify "$file" -R "$REPO" || echo "Failed to verify: $file"
done
from llama_index.core.llms import LLM from llama_index.llms.openai import OpenAI ```
```sh
pip install llama-index-core pip install llama-index-llms-openai pip install llama-index-llms-ollama pip install llama-index-embeddings-huggingface
Examples are in the `docs/examples` folder. Indices are in the `indices` folder (see list of indices below).
To build a simple vector store index using OpenAI:
python import os
os.environ["OPENAI_API_KEY"] = "YOUR_OPENAI_API_KEY"
from llama_index.core import VectorStoreIndex, SimpleDirectoryReader
documents = SimpleDirectoryReader("YOUR_DATA_DIRECTORY").load_data() index = VectorStoreIndex.from_documents(documents)
To build a simple vector store index using non-OpenAI LLMs, e.g. LLMs hosted through Ollama:
python from llama_index.core import Settings, VectorStoreIndex, SimpleDirectoryReader from llama_index.embeddings.huggingface import HuggingFaceEmbedding from llama_index.llms.ollama import Ollama from transformers import AutoTokenizer
业界领先的RAG框架,文档处理能力强,生态成熟社区活跃,是构建智能应用的优选方案。
