Windows 10/11

If using GPU on Windows 10/11 Pro 64-bit, we recommend using Windows installers. This excludes DocTR and PlayWright support.

For newer builds of windows versions of 10/11.

Install

Download Visual Studio 2022: Download Link
- Run Installer, click ok to run, click Continue
- Click on Individual Components
- Search for these in the search bar and click on them:
  - Windows 11 SDK (e.g. 10.0.22000.0)
  - C++ Universal Windows Platform support (e.g. for v143 build tools)
  - MSVC VS 2022 C++ x64/x86 build tools (latest)
  - C++ CMake tools for Windows
- Click Install, and follow through installation, and do not need to launch VS 2022 at end.
Download the MinGW installer: MiniGW
- Run Installer, Click Install, Continue, Install/Run to launch installation manager.
- Select packages to install:
  - minigw32-base
  - mingw32-gcc-g++
- Go to installation tab, then apply changes.
Download and install Miniconda
Run Miniconda shell (not powershell!) as Administrator
Run: set path=%path%;c:\MinGW\msys\1.0\bin\ to get C++ in path. In some cases it may be instead correct to use set path=%path%;c:\MinGW\bin\
Download latest nvidia driver for windows if one has old drivers before CUDA 11.8 supported
Confirm can run nvidia-smi and see driver version

Setup Conda Environment:

 conda create -n h2ogpt -y
 conda activate h2ogpt
 conda install python=3.10 -c conda-forge -y
 python --version  # should say python 3.10.xx
 python -c "import os, sys ; print('hello world')"  # should print "hello world"

GPU Only: Install CUDA

 conda install cudatoolkit=11.8 -c conda-forge -y
 set CUDA_HOME=$CONDA_PREFIX

Install Git:
```
 conda install -c conda-forge git
```

Install h2oGPT:

 git clone https://github.com/h2oai/h2ogpt.git
 cd h2ogpt

Prepare to install dependencies:

set PIP_EXTRA_INDEX_URL=https://download.pytorch.org/whl/cu118 https://huggingface.github.io/autogptq-index/whl/cu118/

Choose cu118+ for A100/H100+. Or for CPU set

set PIP_EXTRA_INDEX_URL=https://download.pytorch.org/whl/cpu

Run [`docs\windows_install.bat](windows_install.bat) for full normal document Q/A installation. To allow all (GPL too) packages, run:
```
set GPLOK=1
docs\windows_install.bat
```
One can pick and choose different optional things to install instead by commenting them out in the shell script, or edit the script if any issues. See script for notes about installation.

See [`docs\windows_install.bat](windows_install.bat) for additional installation instructions for:

Microsoft Word/Excel support
Tesseract OCR support

Note models are stored in C:\Users\<user>\.cache\ for chroma, huggingface, selenium, torch, weaviate, etc. directories. For an absolute windows path, choose --user_path=C:\Users\YourUsername\h2ogpt or something similar for some user YourUsername. If the model is using the GPU, in nvidia-smi or some other GPU monitor program you should see python.exe using GPUs in C (Compute) mode and using GPU resources. Use set CUDA_VISIBLE_DEVICES=0 to pick first model, since llama.cpp models cannot choose which GPU otherwise.

See FAQ for how to run various models. See CPU and GPU for some other general aspects about using h2oGPT on CPU or GPU, such as which models to try, quantization, etc.

Possible Issues

SSL Certification failure when connecting to Hugging Face.
- Your org may be blocking HF
- Try: https://stackoverflow.com/a/75111104
- Or try: https://github.com/huggingface/transformers/issues/17611#issuecomment-1619582900
- Try using proxy.
If you see import problems, then try setting PYTHONPATH in a .bat file:
```
SET PYTHONPATH=.:src:$PYTHONPATH
python generate.py ...
```
for some options ...
For easier handling of command line operations, consider using bash in windows with coreutils.
