projectalicenlutrainer 1.2.0

nluTrainer
A decentralized NLU trainer
The idea behind this small tool is to provide a simple trainer on your Network for Alice to use. Training the NLU is a costly operation and your device running ProjectAlice might get slow at it the more skills you have. In order for Alice to use it, turn on the option delegateNluTraining
Users
To use this, create a Virtual Environment wherever you wish on your main computer, be it Windows, Linux or Mac, on a Synology station, whatever network device that can run python. Make sure this device runs Python 3.7!
python3.7 -m venv venv
Activate your virtual environment and install the nlu trainer with pip:
pip install projectalice-nlu-trainer
That's all you need to install!

Usage
Run the trainer using this command, in your terminal, with admin rights as it needs to install the language packs:
alice-trainer --host ALICE_IP
You can also define some other options with arguments:

-h / --host: Define the Mqtt hostname, generally it's Alice's main unit IP address
-p / --port: Define the Mqtt port, by default 1883
-u / --user: Define a Mqtt username to connect with
-s / --password: Define a Mqtt password to connect with
-f / --tls_file: Define the path to your TLS certificate file to connect with, if you Mqtt server requires it

As you want it to be always running, you might want to automate it to run at computer boot.
