# Vegan Recipe Chatbot

![Screenshot of Chatbot initial interface](docs/assets/chatbot_init.png)

## Quickstart

`git clone` the repo  

```sh
cd lv-recipe-chatbot
```  

Make sure to use the version of python specified in `py_version.txt`  
Create a virtual environment.

```sh
python3 -m venv env
```

Activate the env and install dependencies.

```sh
source env/bin/activate
pip install -r requirements.txt
pip install -r requirements/dev.txt
```

Put API secrets in .env

```sh
cp .env.example .env
```

Edit .env with your secret key(s). Only `OPEN_AI_KEY` is required.

Then start the Gradio demo from within the virtual environment.  

```sh
python3 -m chatbot.app
```

## Dependencies

If a new dependency for devlepment is helpful for developers, add it to `dev.txt`.  
If it is a dependency for the app that is imported in source code, add it to `core.txt`.  
Then run:

```sh
pipreqs --force
```

This will update our `requirements.txt` to include the depenency as it should be pinned in the environment.
