Supported OS and Hardware

GPU mode requires CUDA support via torch and transformers. A 6.9B (or 12GB) model in 8-bit uses 8GB (or 13GB) of GPU memory. 8-bit or 4-bit precision can further reduce memory requirements down no more than about 6.5GB when asking a question about your documents (see low-memory mode).

CPU mode uses GPT4ALL and LLaMa.cpp, e.g. gpt4all-j, requiring about 14GB of system RAM in typical use.

GPU and CPU mode tested on variety of NVIDIA GPUs in Ubuntu 18-22, but any modern Linux variant should work. MACOS support tested on Macbook Pro running Monterey v12.3.1 using CPU mode.

Getting Started

First one needs a Python 3.10 environment. For help installing a Python 3.10 environment, see Install Python 3.10 Environment. On newer Ubuntu systems and environment may be installed by just doing:

sudo apt-get install -y build-essential gcc python3.10-dev
virtualenv -p python3 h2ogpt
source h2ogpt/bin/activate

Check your installation by doing:

python --version # should say 3.10.xx
pip --version  # should say pip 23.x.y ... (python 3.10)

On some systems, pip still refers back to the system one, then one can use python -m pip or pip3 instead of pip or try python3 instead of python.

TLDR

After Python 3.10 environment installed:

git clone https://github.com/h2oai/h2ogpt.git
cd h2ogpt
# broad support, but no training-time or data creation dependencies
for fil in requirements.txt reqs_optional/requirements_optional_langchain.txt reqs_optional/requirements_optional_gpt4all.txt reqs_optional/requirements_optional_langchain.gpllike.txt reqs_optional/requirements_optional_langchain.urls.txt ; do pip install -r $fil ; done
# Optional: support docx, pptx, ArXiv, etc.
sudo apt-get install -y libmagic-dev poppler-utils tesseract-ocr libreoffice
# Optional: for supporting unstructured package
python -m nltk.downloader all

Place all documents in user_path or upload in UI.

UI using GPU with at least 24GB with streaming:

python generate.py --base_model=h2oai/h2ogpt-oasst1-512-12b --load_8bit=True  --score_model=None --langchain_mode='UserData' --user_path=user_path

UI using CPU (streaming not yet supported in UI):

python generate.py --base_model='llama' --prompt_type=wizard2 --score_model=None --langchain_mode='UserData' --user_path=user_path

GPU (CUDA)

For help installing cuda toolkit, see CUDA Toolkit

git clone https://github.com/h2oai/h2ogpt.git
cd h2ogpt
pip install -r requirements.txt --extra-index-url https://download.pytorch.org/whl/cu117
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b --load_8bit=True

Then point browser at http://0.0.0.0:7860 (linux) or http://localhost:7860 (windows/mac) or the public live URL printed by the server (disable shared link with --share=False). For 4-bit or 8-bit support, older GPUs may require older bitsandbytes installed as pip uninstall bitsandbytes -y ; pip install bitsandbytes==0.38.1. For production uses, we recommend at least the 12B model, ran as:

python generate.py --base_model=h2oai/h2ogpt-oasst1-512-12b --load_8bit=True

and one can use --h2ocolors=False to get soft blue-gray colors instead of H2O.ai colors. Here is a list of environment variables that can control some things in generate.py.

Note if you download the model yourself and point --base_model to that location, you'll need to specify the prompt_type as well by running:

python generate.py --base_model=<user path> --load_8bit=True --prompt_type=human_bot

for some user path <user path>.

For quickly using a private document collection for Q/A, place documents (PDFs, text, etc.) into a folder called user_path and run

pip install -r reqs_optional/requirements_optional_langchain.txt
python -m nltk.downloader all  # for supporting unstructured package
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b  --load_8bit=True --langchain_mode=UserData --user_path=user_path

For more ways to ingest on CLI and control see LangChain Readme. For example, for improved pdf handling via pymupdf (GPL) and support for docx, ppt, OCR, and ArXiV run:

sudo apt-get install -y libmagic-dev poppler-utils tesseract-ocr tesseract-ocr libreoffice
pip install -r reqs_optional/requirements_optional_langchain.gpllike.txt

For 4-bit support, the latest dev versions of transformers, accelerate, and peft are required, which can be installed by running:

pip uninstall peft transformers accelerate -y
pip install -r reqs_optional/requirements_optional_4bit.txt

where uninstall is required in case, e.g., peft was installed from GitHub previously. Then when running generate pass --load_4bit=True, which is only supported for certain architectures like GPT-NeoX-20B, GPT-J, LLaMa, etc.

Any other instruct-tuned base models can be used, including non-h2oGPT ones. Larger models require more GPU memory.

CPU

CPU support is obtained after installing two optional requirements.txt files. This does not preclude GPU support, just adds CPU support:

Install base, langchain, and GPT4All, and python LLaMa dependencies:

git clone https://github.com/h2oai/h2ogpt.git
cd h2ogpt
pip install -r requirements.txt  # only do if didn't already do for GPU support, since windows needs --extra-index-url line
pip install -r reqs_optional/requirements_optional_langchain.txt
python -m nltk.downloader all  # for supporting unstructured package
pip install -r reqs_optional/requirements_optional_gpt4all.txt

See GPT4All for details on installation instructions if any issues encountered.

Change .env_gpt4all model name if desired.

model_path_llama=WizardLM-7B-uncensored.ggmlv3.q8_0.bin
model_path_gptj=ggml-gpt4all-j-v1.3-groovy.bin
model_name_gpt4all_llama=ggml-wizardLM-7B.q4_2.bin

For gptj and gpt4all_llama, you can choose a different model than our default choice by going to GPT4All Model explorer GPT4All-J compatible model. One does not need to download manually, the gp4all package will download at runtime and put it into .cache like Hugging Face would. However, gpjt model often gives no output, even outside h2oGPT.

So, for chatting, a better instruct fine-tuned LLaMa-based model for llama.cpp can be downloaded from TheBloke. For example, 13B WizardLM Quantized or 7B WizardLM Quantized. TheBloke has a variety of model types, quantization bit depths, and memory consumption. Choose what is best for your system's specs. However, be aware that LLaMa-based models are not commercially viable.

For 7B case, download WizardLM-7B-uncensored.ggmlv3.q8_0.bin into local path. Then one sets model_path_llama in .env_gpt4all, which is currently the default.

Run generate.py

For LangChain support using documents in user_path folder, run h2oGPT like:

python generate.py --base_model='llama' --prompt_type=wizard2 --score_model=None --langchain_mode='UserData' --user_path=user_path

See LangChain Readme for more details. For no langchain support (still uses LangChain package as model wrapper), run as:

python generate.py --base_model='llama' --prompt_type=wizard2 --score_model=None

No streaming is currently supported for these CPU models in UI, but that will be fixed soon.

When using llama.cpp based CPU models, for computers with low system RAM or slow CPUs, we recommend adding to .env_gpt4all:

use_mlock=False
n_ctx=1024

where use_mlock=True is default to avoid slowness and n_ctx=2048 is default for large context handling. For computers with plenty of system RAM, we recommend adding to .env_gpt4all:

n_batch=1024

for faster handling. One some systems this has no strong effect, but on others may increase speed quite a bit.

Also, for slow and low-memory systems, we recommend using a smaller embedding by using with generrate.py:

python generate.py ... --hf_embedding_model=sentence-transformers/all-MiniLM-L6-v2

where ... means any other options one should add like --base_model etc. This simpler embedding is about half the size as default instruct-large and so uses less disk, CPU memory, and GPU memory if using GPUs.

See also Low Memory for more information about low-memory recommendations.

MACOS

First install Rust:

curl –proto ‘=https’ –tlsv1.2 -sSf https://sh.rustup.rs | sh

Enter new shell and test: rustc --version

When running a Mac with Intel hardware (not M1), you may run into _clang: error: the clang compiler does not support '-march=native'_ during pip install. If so, set your archflags during pip install. eg: ARCHFLAGS="-arch x86_64" pip3 install -r requirements.txt

If you encounter an error while building a wheel during the pip install process, you may need to install a C++ compiler on your computer.

Now go back to normal CPU installation.

Windows 10/11

Follow these steps, which includes the above GPU or CPU install step at one point:

Install Visual Studio 2022 (requires newer windows versions of 10/11) with following selected:
- Windows 11 SDK
- C++ Universal Windows Platform support for development
- MSVC VS 2022 C++ x64/x86 build tools
- C++ CMake tools for Windows
Download the MinGW installer from the MinGW website and select, go to installation tab, then apply changes:
- minigw32-base
- mingw32-gcc-g++
Setup Environment for Windows
Run Miniconda shell (not power shell) as administrator
Run: set path=%path%;c:\MinGW\msys\1.0\bin\ to get C++ in path
Download latest nvidia driver for windows
Confirm can run nvidia-smi and see driver version
Install cuda toolkit from conda: conda install cudatoolkit -c conda-forge as required easily make bitsandbytes work
Run: wsl --install
Now go back to normal GPU or CPU (most general) installation
- IMPORTANT: Run pip install with --extra-index-url https://download.pytorch.org/whl/cu117 as in GPU section
Upgrade to windows GPU version of bitsandbytes if using GPU:

For GPU support of 4-bit and 8-bit, run:

pip uninstall bitsandbytes
pip install https://github.com/jllllll/bitsandbytes-windows-webui/raw/main/bitsandbytes-0.39.0-py3-none-any.whl

unless you have compute capability <7.0, then your GPU only supports 8-bit (not 4-bit) and you should install older bitsandbytes:

pip uninstall bitsandbytes
pip install https://github.com/jllllll/bitsandbytes-windows-webui/raw/main/bitsandbytes-0.38.1-py3-none-any.whl

When running windows on GPUs with bitsandbytes you should see something like:

(h2ogpt) c:\Users\pseud\h2ogpt>python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b --load_8bit=True
bin C:\Users\pseud\.conda\envs\h2ogpt\lib\site-packages\bitsandbytes\libbitsandbytes_cuda118.dll

This share link expires in 72 hours. For free permanent hosting and GPU upgrades (NEW!), check out Spaces: https://huggingface.co/spaces

where bitsandbytes cuda118 was used because conda cuda toolkit is cuda 11.8. You can confirm GPU use via nvidia-smi showing GPU memory consumed.

Note 8-bit inference is about twice slower than 16-bit inference, and the only use of 8-bit is to keep memory profile low.

Bitsandbytes can be uninstalled (pip uninstall bitsandbytes) and still h2oGPT can be used if one does not pass --load_8bit=True.

CLI chat

The CLI can be used instead of gradio by running for some base model, e.g.:

python generate.py --base_model=gptj --cli=True

and for LangChain run:

python make_db.py --user_path=user_path --collection_name=UserData
python generate.py --base_model=gptj --cli=True --langchain_mode=UserData

with documents in user_path folder, or directly run:

python generate.py --base_model=gptj --cli=True --langchain_mode=UserData --user_path=user_path

which will build the database first time. One can also use any other models, like:

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

or for WizardLM:

python generate.py --base_model='llama' --prompt_type=wizard2 --cli=True --langchain_mode=UserData --user_path=user_path

No streaming is currently supported for llama in CLI chat, but that will be fixed soon.

Gradio UI

generate.py by default runs a gradio server with a UI (click for help with UI). Key benefits of the UI include:

Save, export, import chat histories and undo or regenerate last query-response pair
Upload and control documents of various kinds for document Q/A
Choose which specific collection to query, or just chat with LLM
Choose specific documents out of collection for asking questions
Side-by-side 2-model comparison view
RLHF response score evaluation for every query-response

See how we compare to other tools like PrivateGPT, see our comparisons at h2oGPT's LangChain Integration FAQ.

We disable background uploads by disabling telemetry for Hugging Face, gradio, and chroma, and one can additionally avoid downloads (of fonts) by running generate.py with --gradio_offline_level=2. See Offline Documentation for details.

Client API

generate.py by default runs a gradio server, which also gives access to client API using gradio client. See example test code or other tests in our tests. Any element in gradio_runner.py with api_name defined can be accessed via the gradio client.

Python Client Library

An OpenAI compliant client is available. Refer the README for more details.

Connect to Inference Servers

One can connect to Hugging Face text generation inference server, gradio servers running h2oGPT, or OpenAI servers. See README.

Python Wheel

The wheel adds all dependencies including optional dependencies like 4-bit and flash-attention. To build do:

python setup.py sdist bdist_wheel

To install the default dependencies do:

pip install dist/h2ogpt-0.1.0-py3-none-any.whl

replace 0.1.0 with actual version built if more than one. To install additional dependencies, for instance for faiss on GPU, do:

pip install dist/h2ogpt-0.1.0-py3-none-any.whl
pip install dist/h2ogpt-0.1.0-py3-none-any.whl[FAISS]

once whl file is installed, two new scripts will be added to the current environment: h2ogpt_finetune, and h2ogpt_generate.

The wheel is not required to use h2oGPT locally from repo, but makes it portable with all required dependencies.

See setup.py for controlling other options via extras_require.

Development

To create a development environment for training and generation, follow the installation instructions.
To fine-tune any LLM models on your data, follow the fine-tuning instructions.
To create a container for deployment, follow the Docker instructions.
