Caution
This repo has since be archived and is read-only.
With the launch of LlamaIndex v0.10, we are deprecating this llama_hub repo - all integrations (data loaders, tools) and packs are now in the core llama-index Python repository.
LlamaHub will continue to exist. We are revamping llamahub.ai point to all integrations/packs/datasets available in the llama-index repo.
Original creator: Jesse Zhang (GH: emptycrown, Twitter: @thejessezhang), who courteously donated the repo to LlamaIndex!

This is a simple library of all the data loaders / readers / tools / llama-packs / llama-datasets that have been created by the community. The goal is to make it extremely easy to connect large language models to a large variety of knowledge sources. These are general-purpose utilities that are meant to be used in LlamaIndex, LangChain and more!.
Loaders and readers allow you to easily ingest data for search and retrieval by a large language model, while tools allow the models to both read and write to third party data services and sources. Ultimately, this allows you to create your own customized data agent to intelligently work with you and your data to unlock the full capability of next level large language models.
For a variety of examples of data agents, see the notebooks directory. You can find example Jupyter notebooks for creating data agents that can load and parse data from Google Docs, SQL Databases, Notion, and Slack, and also manage your Google Calendar, and Gmail inbox, or read and use OpenAPI specs.
For an easier way to browse the integrations available, check out the website here: https://llamahub.ai/.
These general-purpose loaders are designed to be used as a way to load data into LlamaIndex and/or subsequently used in LangChain.
pip install llama-hub
from llama_index import VectorStoreIndex
from llama_hub.google_docs import GoogleDocsReader
gdoc_ids = ['1wf-y2pd9C878Oh-FmLH7Q_BQkljdm6TQal-c1pUfrec']
loader = GoogleDocsReader()
documents = loader.load_data(document_ids=gdoc_ids)
index = VectorStoreIndex.from_documents(documents)
index.query('Where did the author go to school?')from llama_index.agent import OpenAIAgent
import openai
openai.api_key = 'sk-api-key'
from llama_hub.tools.google_calendar import GoogleCalendarToolSpec
tool_spec = GoogleCalendarToolSpec()
agent = OpenAIAgent.from_tools(tool_spec.to_tool_list())
agent.chat('what is the first thing on my calendar today')
agent.chat("Please create an event for tomorrow at 4pm to review pull requests")For a variety of examples of creating and using data agents, see the notebooks directory.
Note: Make sure you change the description of the Tool to match your use case.
from llama_index import VectorStoreIndex
from llama_hub.google_docs import GoogleDocsReader
from langchain.llms import OpenAI
from langchain.chains.question_answering import load_qa_chain
# load documents
gdoc_ids = ['1wf-y2pd9C878Oh-FmLH7Q_BQkljdm6TQal-c1pUfrec']
loader = GoogleDocsReader()
documents = loader.load_data(document_ids=gdoc_ids)
langchain_documents = [d.to_langchain_format() for d in documents]
# initialize sample QA chain
llm = OpenAI(temperature=0)
qa_chain = load_qa_chain(llm)
question="<query here>"
answer = qa_chain.run(input_documents=langchain_documents, question=question)You can also use the loaders with download_loader from LlamaIndex in a single line of code.
For example, see the code snippets below using the Google Docs Loader.
from llama_index import VectorStoreIndex, download_loader
GoogleDocsReader = download_loader('GoogleDocsReader')
gdoc_ids = ['1wf-y2pd9C878Oh-FmLH7Q_BQkljdm6TQal-c1pUfrec']
loader = GoogleDocsReader()
documents = loader.load_data(document_ids=gdoc_ids)
index = VectorStoreIndex.from_documents(documents)
index.query('Where did the author go to school?')Llama-packs can be downloaded using the llamaindex-cli tool that comes with llama-index:
llamaindex-cli download-llamapack ZephyrQueryEnginePack --download-dir ./zephyr_packOr with the download_llama_pack function directly:
from llama_index.llama_pack import download_llama_pack
# download and install dependencies
LlavaCompletionPack = download_llama_pack(
"LlavaCompletionPack", "./llava_pack"
)(NOTE: in what follows we present the pattern for producing a RAG benchmark with
the RagEvaluatorPack over a LabelledRagDataset. However, there are also other
types of llama-datasets such as LabelledEvaluatorDataset and corresponding llama-packs
for producing benchmarks on their respective tasks. They all follow the similar
usage pattern. Please refer to the README's to learn more on each type of
llama-dataset.)
The primary use of llama-dataset is for evaluating the performance of a RAG system.
In particular, it serves as a new test set (in traditional machine learning speak)
for one to build a RAG over, predict on, and subsequently perform evaluations
comparing the predicted response versus the reference response. To perform the
evaluation, the recommended usage pattern involves the application of the
RagEvaluatorPack. We recommend reading the docs for the "Evaluation" module for
more information on all of our llama-dataset's.
from llama_index.llama_dataset import download_llama_dataset
from llama_index.llama_pack import download_llama_pack
from llama_index import VectorStoreIndex
# download and install dependencies for benchmark dataset
rag_dataset, documents = download_llama_dataset(
"PaulGrahamEssayDataset", "./data"
)
# build basic RAG system
index = VectorStoreIndex.from_documents(documents=documents)
query_engine = VectorStoreIndex.as_query_engine()
# evaluate using the RagEvaluatorPack
RagEvaluatorPack = download_llama_pack(
"RagEvaluatorPack", "./rag_evaluator_pack"
)
rag_evaluator_pack = RagEvaluatorPack(
rag_dataset=rag_dataset,
query_engine=query_engine
)
benchmark_df = rag_evaluate_pack.run() # async arun() supported as wellLlama-datasets can also be downloaded directly using llamaindex-cli, which comes installed with the llama-index python package:
llamaindex-cli download-llamadataset PaulGrahamEssayDataset --download-dir ./dataAfter downloading them from llamaindex-cli, you can inspect the dataset and
it source files (stored in a directory /source_files) then load them into python:
from llama_index import SimpleDirectoryReader
from llama_index.llama_dataset import LabelledRagDataset
rag_dataset = LabelledRagDataset.from_json("./data/rag_dataset.json")
documents = SimpleDirectoryReader(
input_dir="./data/source_files"
).load_data()Adding a loader/tool/llama-pack simply requires forking this repo and making a Pull Request. The Llama Hub website will update automatically when a new llama-hub release is made. However, please keep in mind the following guidelines when making your PR.
Create a new Python virtual environment. The command below creates an environment in .venv,
and activates it:
python -m venv .venv
source .venv/bin/activateif you are in windows, use the following to activate your virtual environment:
.venv\scripts\activateInstall poetry:
pip install poetryInstall the required dependencies (this will also install llama_index):
poetry installThis will create an editable install of llama-hub in your venv.
For loaders, create a new directory in llama_hub, for tools create a directory in llama_hub/tools, and for llama-packs create a directory in llama_hub/llama_packs It can be nested within another, but name it something unique because the name of the directory will become the identifier for your loader (e.g. google_docs). Inside your new directory, create a __init__.py file specifying the module's public interface with __all__, a base.py file which will contain your loader implementation, and, if needed, a requirements.txt file to list the package dependencies of your loader. Those packages will automatically be installed when your loader is used, so no need to worry about that anymore!
If you'd like, you can create the new directory and files by running the following script in the llama_hub directory. Just remember to put your dependencies into a requirements.txt file.
./add_loader.sh [NAME_OF_NEW_DIRECTORY]
Inside your new directory, create a README.md that mirrors that of the existing ones. It should have a summary of what your loader or tool does, its inputs, and how it is used in the context of LlamaIndex and LangChain.
Finally, add your loader to the llama_hub/library.json file (or for the equivalent library.json under tools/ or llama-packs/) so that it may be used by others. As is exemplified by the current file, add the class name of your loader or tool, along with its ID, author, etc. This file is referenced by the Llama Hub website and the download function within LlamaIndex.
Create a PR against the main branch. We typically review the PR within a day. To help expedite the process, it may be helpful to provide screenshots (either in the PR or in the README directly) Show your data loader or tool in action!
Similar to the process of adding a tool / loader / llama-pack, adding a llama- datset also requires forking this repo and making a Pull Request. However, for a llama-dataset, only its metadata is checked into this repo. The actual dataset and it's source files are instead checked into another Github repo, that is the llama-datasets repository. You will need to fork and clone that repo in addition to forking and cloning this one.
Please ensure that when you clone the llama-datasets repository, that you set
the environment variable GIT_LFS_SKIP_SMUDGE prior to calling the git clone
command:
# for bash
GIT_LFS_SKIP_SMUDGE=1 git clone [email protected]:<your-github-user-name>/llama-datasets.git # for ssh
GIT_LFS_SKIP_SMUDGE=1 git clone https://github.com/<your-github-user-name>/llama-datasets.git # for https
# for windows its done in two commands
set GIT_LFS_SKIP_SMUDGE=1
git clone [email protected]:<your-github-user-name>/llama-datasets.git # for ssh
set GIT_LFS_SKIP_SMUDGE=1
git clone https://github.com/<your-github-user-name>/llama-datasets.git # for httpsThe high-level steps for adding a llama-dataset are as follows:
- Create a
LabelledRagDataset(the initial class of llama-dataset made available on llama-hub) - Generate a baseline result with a RAG system of your own choosing on the
LabelledRagDataset - Prepare the dataset's metadata (
card.jsonandREADME.md) - Submit a Pull Request to this repo to check in the metadata
- Submit a Pull Request to the llama-datasets repository to check in the
LabelledRagDatasetand the source files
To assist with the submission process, we have prepared a submission template notebook that walks you through the above-listed steps. We highly recommend that you use this template notebook.
(NOTE: you can use the above process for submitting any of our other supported
types of llama-datasets such as the LabelledEvaluatorDataset.)
python3.9 -m venv .venv
source .venv/bin/activate
pip3 install -r test_requirements.txt
poetry run make testIf you want to track the latest version updates / see which loaders are added to each release, take a look at our full changelog here!
There is an argument called loader_hub_url in download_loader that defaults to the main branch of this repo. You can set it to your branch or fork to test your new loader.
If you have a data loader PR, by default let's try to create it against LlamaHub! We will make exceptions in certain cases (for instance, if we think the data loader should be core to the LlamaIndex repo).
For all other PR's relevant to LlamaIndex, let's create it directly against the LlamaIndex repo.
We have just started offering badges to our contributors. At the moment, we're focused on our early adopters and official partners, but we're gradually opening up badge consideration to all submissions. If you're interested in being considered, please review the criteria below and if everything aligns, feel free to contact us via community Discord.
We are still refining our criteria but here are some aspects we consider:
Quality
- Code Quality illustrated by the use of coding standards and style guidelines.
- Code readability and proper documentation.
Usability
- Self-contained module with no external links or libraries, and it is easy to run.
- Module should not break any existing unit tests.
Safety
- Safety considerations, such as proper input validation, avoiding SQL injection, and secure handling of user data.
Community Engagement & Feedback
- The module's usefulness to the library's users as gauged by the number of likes, downloads, etc.
- Positive feedback from module users.
Note:
- It's possible that we decide to award a badge to a subset of your submissions based on the above criteria.
- Being a regular contributor doesn't guarantee a badge, we will still look at each submission individually.
