• Features
• Installation
• Usage
• Configuration
• GPU

Features

• Supports many GGML models via C Transformers
• Supports 🤗 Transformers
• GPU support
• Highly configurable via chatdocs.yml

Installation

Install the tool using:

pip install chatdocs

Download the AI models using:

chatdocs download

Now it can be run offline without internet connection.

Usage

Add a directory containing documents to chat with using:

chatdocs add /path/to/documents

The processed documents will be stored in db directory by default.

Chat with your documents using:

chatdocs chat

Configuration

All the configuration options can be changed using the chatdocs.yml config file. Create a chatdocs.yml file in some directory and run all commands from that directory. For reference, see the default chatdocs.yml file.

You don't have to copy the entire file, just add the config options you want to change as it will be merged with the default config. For example, see tests/fixtures/chatdocs.yml which changes only some of the config options.

Embeddings

To change the embeddings model, add and change the following in your chatdocs.yml:

embeddings:
  model: hkunlp/instructor-large

Note: When you change the embeddings model, delete the db directory and add documents again.

C Transformers

To change the C Transformers model, add and change the following in your chatdocs.yml:

ctransformers:
  model: TheBloke/Wizard-Vicuna-7B-Uncensored-GGML
  model_type: llama

Note: When you add a new model for the first time, run chatdocs download to download the model before using it.

You can also use an existing local model file:

ctransformers:
  model: /path/to/ggml-model.bin
  model_type: llama

🤗 Transformers

To use 🤗 Transformers, add the following to your chatdocs.yml:

llm: huggingface

To change the 🤗 Transformers model, add and change the following in your chatdocs.yml:

huggingface:
  model: TheBloke/Wizard-Vicuna-7B-Uncensored-HF

Note: When you add a new model for the first time, run chatdocs download to download the model before using it.

GPU

Embeddings

To enable GPU (CUDA) support for the embeddings model, add the following to your chatdocs.yml:

embeddings:
  model_kwargs:
    device: cuda

You may have to reinstall PyTorch with CUDA enabled by following the instructions here.

C Transformers

Note: Currently only LLaMA GGML models have GPU support.

To enable GPU (CUDA) support for the C Transformers model, add the following to your chatdocs.yml:

ctransformers:
  config:
    gpu_layers: 50

You should also reinstall the ctransformers package with CUDA enabled:

pip uninstall ctransformers --yes
CT_CUBLAS=1 pip install ctransformers --no-binary ctransformers

Show commands for Windows

On Windows PowerShell run:

$env:CT_CUBLAS=1
pip uninstall ctransformers --yes
pip install ctransformers --no-binary ctransformers

On Windows Command Prompt run:

set CT_CUBLAS=1
pip uninstall ctransformers --yes
pip install ctransformers --no-binary ctransformers

🤗 Transformers

To enable GPU (CUDA) support for the 🤗 Transformers model, add the following to your chatdocs.yml:

huggingface:
  device: 0

You may have to reinstall PyTorch with CUDA enabled by following the instructions here.
