AI Smart Human Assistant Library

AISHA Lib: A High-Level Abstraction for Building AI Assistants

In the evolving landscape of artificial intelligence, the development of smart assistants has become increasingly prevalent. To streamline this process, the AISHA (AI Smart Human Assistant) Lib offers a high-level abstraction designed for creating AI assistants. This versatile library supports various large language models (LLMs) and different LLM backends, providing developers with a powerful and flexible toolset.

Environment

To create a Python virtual environment, use the command:

conda env create -f environment.yml

Installation

pip install aishalib

Supported Models

The following LLM models are supported:

• microsoft/Phi-3-medium-128k-instruct
• CohereForAI/c4ai-command-r-v01
• google/gemma-2-27b-it
• Qwen/Qwen2-72B-Instruct

LLM backends

The following LLM backends are supported:

• Llama.cpp Server API

Install CUDA toolkit for Llama.cpp compilation

Please note that the toolkit version must match the driver version. The driver version can be found using the nvidia-smi command. To install toolkit for CUDA 12.5 you need to run the following commands:

CUDA_TOOLKIT_VERSION=12-5
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt update
sudo apt -y install cuda-toolkit-${CUDA_TOOLKIT_VERSION}
echo -e '
export CUDA_HOME=/usr/local/cuda
export PATH=${CUDA_HOME}/bin:${PATH}
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64:$LD_LIBRARY_PATH
' >> ~/.bashrc
