title: Installing Amica

order: 2

To run this project locally, clone or download the repository.

git clone [email protected]:semperai/amica.git

Install the required packages.

npm install

After installing the packages, start the development web server using the following command.

npm run dev

Adding new Assets

Make sure to run npm run generate:paths after adding new assets, and npm run build to see your new files.

Background

New background images can be places in ./public/bg/.private and will be automatically loaded.

VRM

New VRM files can be placed in ./public/vrm/.private and will be automatically loaded.

Animation

New animation files can be placed in ./public/animation/.private and will be automatically loaded.

Setup LLM, TTS and STT

Local LLM Setup

We will use llama.cpp for local LLM. However, you can see how to do this with other LLMs with the various guides.

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
make server -j 4

# download https://huggingface.co/TheBloke/OpenHermes-2.5-Mistral-7B-GGUF/blob/main/openhermes-2.5-mistral-7b.Q5_K_M.gguf
# save this file into llama.cpp/models folder

# when the download is complete you can start the server and load the model
# you can save this command in a file called start_server.sh
./server -t 4 -c 4096 -ngl 35 -b 512 --mlock -m models/openhermes-2-mistral-7b.Q5_K_M.gguf

Now go to http://127.0.0.1:8080 in browser and test it works.

Local Audio

We will use a simple http server which implements Coqui TTS and faster-whisper with api endpoints matching OpenAIs.

git clone https://github.com/semperai/basic-openai-api-wrapper
cd basic-openai-api-wrapper
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python server.py

Now you have OpenAI compatible transcription and TTS server running on 127.0.0.1:5000.

Now, configure settings to use local services:

settings -> chatbot -> chatbot backend:
    set `Chatbot Backend` to `llama.cpp`

settings -> chatbot -> llama.cpp:
    set `API URL` to `http://127.0.0.1:8080`

settings -> text-to-speech -> tts backend:
    set `TTS Backend` to `OpenAI TTS`

settings -> text-to-speech -> openai:
    set `API URL` to `http://127.0.0.1:5000`

settings -> speech-to-text -> stt backend:
    set `STT Backend` to `Whisper (OpenAI)`

settings -> speech-to-text -> whisper (openai):
    set `OpenAI URL` to `http://127.0.0.1:5000`

Test that everything works. If something doesn't, open the debug window or your developer console in web browser to see if you can see what the error is.
