🚧 Under development 🚧

Server/client BERT fine tunning app using active learning

Python refactoring of R Shiny ActiveTigger app (Julien Boelaert & Etienne Ollion)

Installation

You can install activetigger via pip (be careful to use Python 3.11):

pip install activetigger

Start the server

Create a config file config.yaml in the directory where you want to launch the server :

• path : path to store files (for instance ./data)
• secret_key : to secure tokens. To generate it openssl rand -hex 32C
• path_models: absolute path to fasttext models

Then, to launch the server (on 0.0.0.0 port 8000 by default). You can configurate exposed port if needed.

python -m activetigger

Otherwise, you can launch only the API with uvicorn:

uvicorn activetigger.api:app --host 0.0.0.0 --port 80 --reload

Users management

You can create/delete users with the root account.

You can also create a add_users.yaml file with the users to add when the server starts :

user1: password1
user2: password2
