h2oGPT integration with LangChain and Chroma/FAISS/Qdrant/Weaviate for Vector DB

Our goal is to make it easy to have private offline document question-answer using LLMs.

Get Started

Follow the get started steps in the main README. In this readme, we focus on other optional aspects.

To support GPU FAISS database, run:

pip install -r reqs_optional/requirements_optional_gpu_only.txt

or for CPU FAISS database, run:

pip install -r reqs_optional/requirements_optional_cpu_only.txt

or for Qdrant/Weaviate, run:

pip install -r reqs_optional/requirements_optional_langchain.txt

Note: If you upload files and one of the files is a zip that contains images to be read by Florence-2/DocTR or PDFs to be read by DocTR, this will currently fail with:

Cannot re-initialize CUDA in forked subprocess. To use CUDA with multiprocessing, you must use the 'spawn' start method

Please upload the zip separately for now.

Supported Data Types in UI

  • Files : All Native and Meta Data Types as file(s),
  • URL : Any URL (i.e. http:// or https://),
  • ArXiv : Any ArXiv name (e.g. arXiv:1706.03762),
  • Text : Paste Text into UI.

Supported Meta Tasks

  • ScrapeWithPlayWRight : Async Web Scraping using headless Chromium via PlayWright
  • ScrapeWithHttp : Async Web Scraping using aiohttp (slower than PlayWright)
  • Timing
    • Typical page like passing https://github.com/h2oai/h2ogpt takes about 300 seconds to process at a default depth of 1 with about 140 pages.
    • No good progress indicators from these packages, so just have to wait.
  • Depth:
    • Set env CRAWL_DEPTH=<depth> to control depth for some integer <depth>, where 0 means only the actual page, 1 means that page + all links on that page, etc. CRAWL_DEPTH=1 by default to avoid excessive crawling.
    • Set env ALL_CRAWL_DEPTH=<depth> to force all url loaders to crawl at some depth (will be slower than async ones)
  • BS4:
    • Set env HTML_TRANS=BS4 to use BS4 to transform instead of Html2TextTransformer. Set BS4_TAGS env to some string of list to set tags.
      • e.g. export BS4_TAGS="['span']"
    • Scrape text content tags such as <p>, <li>, <div>, and <a> tags from the HTML content:
      • <p>: The paragraph tag. It defines a paragraph in HTML and is used to group related sentences and/or phrases.
      • <li>: The list item tag. It is used within ordered (<ol>) and unordered (<ul>) lists to define individual items within the list.
      • <div>: The division tag. It is a block-level element used to group other inline or block-level elements.
      • <a>: The anchor tag. It is used to define hyperlinks.
      • <span>: an inline container used to mark up a part of a text, or a part of a document. For many news websites (e.g., WSJ, CNN), headlines and summaries are all in <span> tags.
  • ScrapeWithHttp:
    • Can change code in src/gpt_langchain.py to change requests_per_second=10 to some other value.

Adding new file types

The function file_to_doc controls the ingestion, with allowed ones listed. If one wants to add a new file type, add it to the list file_types, and then add an entry in file_to_doc() function.

Metadata is added using add_meta function, and other metadata, like chunk_id, is added after chunking. One could add a new step to add metadata to page_content to each langchain Document.

Database creation

To use some example databases (will overwrite UserData make above unless change options) and run generate after, do:

python src/make_db.py --download_some=True
python generate.py --base_model=HuggingFaceH4/zephyr-7b-beta --langchain_mode=UserData --langchain_modes="['UserData', 'wiki', 'MyData', 'github h2oGPT', 'DriverlessAI docs']"

which downloads example databases. This obtains files from some pre-generated databases. A large Wikipedia database is also available.

To build the database first outside chatbot, then run generate after, do:

python src/make_db.py
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b --langchain_mode=UserData

To add data to the existing database, then run generate after, do:

python src/make_db.py --add_if_exists=True
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b --langchain_mode=UserData

By default, generate.py will load an existing UserData database and add any documents added to user_path or change any files that have changed. To avoid detecting any new files, just avoid passing --user_path=user_path, which sets it to None, i.e.:

python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b --langchain_mode=UserData

which will avoid using user_path since it is no longer passed. Otherwise, when passed, any new files will be added or changed (by hash) files will be updated (delete old sources and add new sources).

If you have enough GPU memory for embedding, but not the LLM as well, then a less private mode is to use the OpenAI model.

python generate.py  --inference_server=openai_chat --base_model=gpt-3.5-turbo --score_model=None --langchain_mode=LLM --langchain_modes="['LLM', 'UserData', 'MyData']"

and if you want to push the image caption model to get better captions, this can be done if have enough GPU memory or if use OpenAI:

python generate.py  --inference_server=openai_chat --base_model=gpt-3.5-turbo --score_model=None --langchain_mode=LLM --langchain_modes="['LLM', 'UserData', 'MyData']" --captions_model=microsoft/Florence-2-large

Similar commands can be used for Azure OpenAI, e.g.

OPENAI_API_KEY=<key> python generate.py --inference_server="openai_azure_chat:<deployment_name>:<base_url>:<api_version>" --base_model=gpt-3.5-turbo --h2ocolors=False --langchain_mode=UserData

To speed-up ingestion of PDFs (skip complex PDFs that fail with pymupdf) and to use faster embedding model, can run differently. Can also use docker to avoid installing dependencies:

mkdir -p ~/.cache
mkdir -p ~/save
mkdir -p ~/user_path
mkdir -p ~/db_dir_UserData
docker run \
       --gpus all \
       --runtime=nvidia \
       --shm-size=2g \
       --rm --init \
       --network host \
       -v /etc/passwd:/etc/passwd:ro \
       -v /etc/group:/etc/group:ro \
       -u `id -u`:`id -g` \
       -v "${HOME}"/.cache:/workspace/.cache \
       -v "${HOME}"/save:/workspace/save \
       -v "${HOME}"/user_path:/workspace/user_path \
       -v "${HOME}"/db_dir_UserData:/workspace/db_dir_UserData \
       gcr.io/vorvan/h2oai/h2ogpt-runtime:0.2.1 /workspace/src/make_db.py --verbose --use_unstructured_pdf=False --enable_pdf_ocr=False --hf_embedding_model=BAAI/bge-small-en-v1.5 --cut_distance=10000

This will consume about 100 PDFs per minute on average, and embedding part takes about 5 minutes for 300 PDFs. For multilingual, use BAAI/bge-m3 that uses more memory, so you may need to set ENV CHROMA_MAX_BATCH_SIZE=1 or similar values to avoid GPU OOM.

Multiple embeddings and sources

We only support one embedding at a time for each database.

So you could use src/make_db.py to make the DB for different embeddings (--hf_embedding_model like gen.py, any HF model) for each collection (e.g. UserData, UserData2) for each source folders (e.g. user_path, user_path2), and then at generate.py time you can specify those different collection names in --langchain_modes and --langchain_modes and --langchain_mode_paths. For example:

python src/make_db.py --user_path=user_path --collection_name=UserData --langchain_type=shared --hf_embedding_model=hkunlp/instructor-large
python src/make_db.py --user_path=user_path2 --collection_name=UserData2 --langchain_type=shared --hf_embedding_model=sentence-transformers/all-MiniLM-L6-v2

Note that shared is the default type already, but we show above to show what options are relevant if want to change them. Then run:

python generate.py --base_model='llama' --prompt_type=llama2 --score_model=None --langchain_mode='UserData' --langchain_modes=['UserData','UserData2'] --langchain_mode_paths={'UserData':'user_path','UserData2':'user_path2'} --langchain_mode_types={'UserData':'shared','UserData2':'shared'} --model_path_llama=https://huggingface.co/TheBloke/Llama-2-7b-Chat-GGUF/resolve/main/llama-2-7b-chat.Q6_K.gguf --max_seq_len=4096

or choose 13B. And watch out for the use of whitespace. For langchain_mode_paths you can pass surrounded by "'s and have spaces.

Per-User DataBase

See discussion here.

E.g. a folder might already have some databases, like for user jon be:

(h2ogpt) jon@pseudotensor:~/h2ogpt$ ls -alrt users/jon/
total 84
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_yuppy/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_xxx/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_testsum1/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_feefef/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_dudedata/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_dogdata1/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_dogdata/
drwx------   2 jon jon  4096 Apr  8 01:49 db_dir_aaaaa/
drwx------  12 jon jon  4096 Apr  8 02:11 ./
drwx------   3 jon jon  4096 Apr  8 02:12 db_dir_asdfasdf/
drwx------   3 jon jon  4096 Apr  9 08:44 db_dir_MyData/
drwx------ 431 jon jon 36864 Apr 16 11:20 ../

for personal collections.

To make a new one for the user, fill user_path_jon with documents (can be soft or hard linked to avoid dups across multiple users), do:

python src/make_db.py --user_path=user_path_jon --collection_name=JonData --langchain_type=personal --hf_embedding_model=hkunlp/instructor-large --persist_directory=users/jon/db_dir_JonData

Then you'll have:

(h2ogpt) jon@pseudotensor:~/h2ogpt$ ls -alrt users/jon/db_dir_JonData/
total 264
drwx------ 13 jon jon   4096 Apr 16 12:28 ../
drwx------  2 jon jon   4096 Apr 16 12:28 d7ccacb6-93fe-4380-9340-b7f5edffb655/
-rw-------  1 jon jon 249856 Apr 16 12:28 chroma.sqlite3
-rw-------  1 jon jon     41 Apr 16 12:28 embed_info
drwx------  3 jon jon   4096 Apr 16 12:28 ./

You can add that database to the auth.json for their entry if using auth.json type file, and they will see when they login.

Or you can have the user add that collection by name (JonData). i.e. In Document Selection they would go to Add Collection and enter JonData, personal. A path could be added if you want them to be able to add to the path, else avoid. After hitting enter they will see the collection and it will become the default with the documents you added tot he database.

Choosing document types

import sys
sys.path.append('src')
from src.gpt_langchain import get_supported_types
non_image_types, image_types, video_types = get_supported_types()
print(non_image_types)
print(image_types)

Select types, and pass to make_db like:

python src/make_db.py --user_path="/home/jon/Downloads/demo_data" --collection_name=VAData --enable_pdf_ocr='off' --selected_file_types="['pdf', 'html', 'htm']"
python generate.py  --base_model='llama' --prompt_type=llama2 --score_model=None --langchain_mode=VAData --langchain_modes=['VAData'] --model_path_llama=https://huggingface.co/TheBloke/Llama-2-7b-Chat-GGUF/resolve/main/llama-2-7b-chat.Q6_K.gguf --max_seq_len=4096

or choose 13B.

To ensure a collection is persisted even when not using any authentication, be sure it is shared type, e.g.:

python generate.py --base_model='llama' --prompt_type=llama2 --score_model=None --max_max_new_tokens=2048 --max_new_tokens=1024 \
       --visible_tos_tab=False --visible_hosts_tab=False --visible_models_tab=False \
       --langchain_modes="['LLM','PersistData']" --langchain_mode=PersistData \
       --langchain_mode_types="{'PersistData':'shared'}" \
       --top_k_docs=-1 --max_time=360 --save_dir=save \
       --model_path_llama=https://huggingface.co/TheBloke/Llama-2-7b-Chat-GGUF/resolve/main/llama-2-7b-chat.Q6_K.gguf \
       --max_seq_len=4096

or choose 13B.

Note about Embeddings

The default embedding for GPU is instructor-large since most accurate, however, it leads to excessively high scores for references due to its flat score distribution. For CPU the default embedding is all-MiniLM-L6-v2, and it has a sharp distribution of scores, so references make sense, but it is less accurate.

Note about FAISS

FAISS filtering is not supported in h2oGPT yet, ask if this is desired to be added. So subset by document does not function for FAISS.

Using Weaviate

About

Weaviate is an open-source vector database designed to scale seamlessly into billions of data objects. This implementation supports hybrid search out-of-the-box (meaning it will perform better for keyword searches).

You can run Weaviate in 5 ways:

  • SaaS – with Weaviate Cloud Services (WCS).

    WCS is a fully managed service that takes care of hosting, scaling, and updating your Weaviate instance. You can try it out for free with a sandbox that lasts for 14 days.

    To set up a SaaS Weaviate instance with WCS:

    1. Navigate to Weaviate Cloud Console.
    2. Register or sign in to your WCS account.
    3. Create a new cluster with the following settings:
      • Subscription Tier – Free sandbox for a free trial, or contact hello@weaviate.io for other options.
      • Cluster name – a unique name for your cluster. The name will become part of the URL used to access this instance.
      • Enable Authentication? – Enabled by default. This will generate a static API key that you can use to authenticate.
    4. Wait for a few minutes until your cluster is ready. You will see a green tick ✔️ when it's done. Copy your cluster URL.

  • Hybrid SaaS

    If you need to keep your data on-premise for security or compliance reasons, Weaviate also offers a Hybrid SaaS option: Weaviate runs within your cloud instances, but the cluster is managed remotely by Weaviate. This gives you the benefits of a managed service without sending data to an external party.

    The Weaviate Hybrid SaaS is a custom solution. If you are interested in this option, please reach out to hello@weaviate.io.

  • Self-hosted – with a Docker container

    To set up a Weaviate instance with Docker:

    1. Install Docker on your local machine if it is not already installed.
    2. Install the Docker Compose Plugin
    3. Download a docker-compose.yml file with this curl command:
curl -o docker-compose.yml "https://configuration.weaviate.io/v2/docker-compose/docker-compose.yml?modules=standalone&runtime=docker-compose&weaviate_version=v1.19.6"
 Alternatively, you can use Weaviate's docker compose [configuration tool](https://weaviate.io/developers/weaviate/installation/docker-compose) to generate your own `docker-compose.yml` file.

  1. Run docker compose up -d to spin up a Weaviate instance.

    To shut it down, run docker compose down.

  • Self-hosted – with a Kubernetes cluster

    To configure a self-hosted instance with Kubernetes, follow Weaviate's documentation.|

  • Embedded - start a Weaviate instance right from your application code using the client library

    This code snippet shows how to instantiate an embedded Weaviate instance and upload a document:

  import weaviate
  from weaviate.embedded import EmbeddedOptions

  client = weaviate.Client(
    embedded_options=EmbeddedOptions()
  )

  data_obj = {
    "name": "Chardonnay",
    "description": "Goes with fish"
  }

  client.data_object.create(data_obj, "Wine")

Refer to the documentation for more details about this deployment method.

How To Use

Simply pass the --db_type=weaviate argument. For example:

python src/make_db.py --db_type=weaviate
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b \
   --langchain_mode=UserData \
   --db_type=weaviate

will use an embedded Weaviate instance.

If you have a Weaviate instance hosted at say http://localhost:8080, then you need to define the WEAVIATE_URL environment variable before running the scripts:

WEAVIATE_URL=http://localhost:8080 python src/make_db.py --db_type=weaviate
WEAVIATE_URL=http://localhost:8080 python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b \
   --langchain_mode=UserData \
   --db_type=weaviate

Similarly, if you had set up your Weaviate instance with a username and password using the OIDC Resource Owner Password flow, you will need to define the following additional environment variables:

  • WEAVIATE_USERNAME: the username used for authentication
  • WEAVIATE_PASSWORD: the password used for authentication
  • WEAVIATE_SCOPE: optional, defaults to "offline_access"

Notes:

  • Since h2oGPT is focused on privacy, connecting to Weaviate via WCS is not supported as that will expose your data to a 3rd party
  • Weaviate doesn't know about persistent directories throughout code and maintains locations based on the collection name
  • Weaviate doesn't support query of all metadata except via similarity search up to 10k documents, so a full list of sources is not possible in h2oGPT UI for Update UI with Document(s) from DB or Show Sources from DB

Using Qdrant

About

Qdrant is an open-source, high-performance vector search engine/database. It is built with Rust for large data on a billion scale.

You can find installation instructions in the Qdrant documentation.

Usage

Set the db_type option value to qdrant:

python src/make_db.py --db_type=qdrant
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b \
   --langchain_mode=UserData \
   --db_type=qdrant

Qdrant's Python client also supports in-memory instances for prototyping, which is the default in H2OGPT.

You can use environment variables to configure your Qdrant connection. For example:

QDRANT_URL=http://localhost:8080 QDRANT_API_KEY="<YOUR_KEY>" python src/make_db.py --db_type=qdrant
QDRANT_URL=http://localhost:8080 QDRANT_API_KEY="<YOUR_KEY>" python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b \
   --langchain_mode=UserData \
   --db_type=qdrant

The available configurations are:

ENV name Description
QDRANT_URL Either host or a fully qualified URL. Eg. http://localhost:6333
QDRANT_PORT Port of the REST API interface. Default: 6333
QDRANT_GRPC_PORT Port of the gRPC interface. Default: 6334
QDRANT_PREFER_GPRC If true - use the gRPC interface whenever possible in custom methods.
QDRANT_HTTPS If true - use HTTPS(SSL) protocol.
QDRANT_API_KEY API key for authentication in Qdrant Cloud.
QDRANT_PREFIX If set, add prefix to the REST URL path. Example: service/v1 will result in http://localhost:6333/service/v1/{qdrant-endpoint} for REST API.
QDRANT_TIMEOUT Timeout for REST and gRPC API requests. Default: 5.0 seconds for REST and unlimited for gRPC
QDRANT_HOST Host name of Qdrant service. If url and host are not set, defaults to 'localhost'.
QDRANT_PATH Persistence path for QdrantLocal. Eg. h2o_data/qdrant

Document Question-Answer FAQ

What is UserData and MyData?

UserData: Shared with anyone who is on your server. Persisted across sessions in a single location for the entire server. Control upload via allow_upload_to_user_data option. Useful for collaboration.

MyData: Personal space inaccessible if one goes into a new browser session. Useful for public demonstrations so that every instance is independent. It is useful if the user cannot upload to shared UserData and wants to do Q&A.

It's a work in progress to add other persistent databases and to have MyData persisted across browser sessions via cookie or other authentication.

Why does the source link not work?

For links to direct to the document and download to your local machine, the source documents must still be present on the host system where the database was created, e.g. user_path for UserData by default. If the database alone is copied somewhere else, that host won't have access to the documents. URL links like Wikipedia will still work normally on any host.

What is h2oGPT's LangChain integration like?

  • PrivateGPT . By comparison, h2oGPT has:

    • UI with chats export, import, selection, regeneration, and undo
    • UI and document Q/A, upload, download, and list
    • Parallel ingest of documents, using GPUs if present for vector embeddings, with progress bar in stdout
    • Choose which specific collection
    • Choose to get a response regarding all documents or specifically selected document(s) out of a collection
    • Choose to chat with LLM, get a one-off LLM response to a query, or talk to a collection
    • GPU support from any hugging face model for the highest performance
    • Upload many types of docs, from PDFs to images (caption or OCR), URLs, ArXiv queries, or just plain text inputs
    • Server-Client API through Gradio client
    • RLHF score evaluation for every response
    • UI with side-by-side model comparisons against two models at a time with independent chat streams
    • Fine-tuning framework with QLORA 4-bit, 8-bit, 16-bit GPU fine-tuning or CPU fine-tuning

  • localGPT. By comparison, h2oGPT has similar benefits as compared to localGPT. Both h2oGPT and localGPT can use GPUs for LLMs and embeddings, including the latest Vicuna or WizardLM models.

  • Quiver. By comparison, Quiver requires docker but also supports audio and video and currently only supports OpenAI models and embeddings.

  • LM Studio. Nice control over models and llama settings, good Windows installer.

  • DocsGPT. More limited document support.

  • GPT4-PDF-Chatbot-LangChain. Uses OpenAI, pinecone, etc. No longer maintained.
