Your very own Assistant. Because you deserve it.

Requirements

You need python 3 with the following requirements:

  • Python 3.x
  • min. 12 Gb RAM
  • min. 30 Gb availible disk space
  • (optional, recommended) min. 11 Gb VRAM on a Nvidia GPU
  • May require an internet connection to download the models initially

Installation

To install Assistant use pip:

pip install assistant

Using an arch based distro. (Availible on the AUR and pre-built on Singularity)

pacman -S python-assistant

From source:

pip install -U git+https://gitlab.com/waser-technologies/technologies/assistant.git

From local source

git clone https://gitlab.com/waser-technologies/technologies/assistant.git ./assistant
cd assistant
pip install -U .

Start the service

To talk with Assistant, you need to load the service up first.

cp ./assistant.service.example /usr/usr/lib/systemd/user/assistant.service
systemctl --user enable --now dmt assistant

(optional) enable listen for assistant

cp ./assistant.listen.service.example /usr/usr/lib/systemd/user/assistant.listen.service
systemctl --user enable --now assistant.listen

Or manually from python:

dmt -S & # load the NLP models #
sleep 60 && # wait for the models to load #    
python -m assistant.as_service & # Assistance is a service #    
python -m listen.STT.as_service & # optional #   
# let assistant listen when you speak #    
python -m assistant.listen

Once the service is up, you can type or say assistant.

Note that you need the dmt service loaded up first. First time you use the dmt to serve NLP models with rasa, the dmt will download the latest pre-build models for your language and install the required domains.

However it's recommended that you acually use the dmt to train your own models based on the domains you want to use and have installed.

# List installed domains
dmt -L
# Validate the data and train
dmt -V -T
# You now can serve your last trained model
dmt -S

Usage

Just call Assistant like any other shell.

 assistant --help
usage: assistant [-h] [-V] [-c COMMAND] [-i] [-l] [--rc RC [RC ...]] [--no-rc]
                 [--no-script-cache] [--cache-everything] [-D ITEM]
                 [--shell-type {b,best,d,dumb,ptk,ptk1,ptk2,prompt-toolkit,prompt_toolkit,prompt-toolkit1,prompt-toolkit2,prompt-toolkit3,prompt_toolkit3,ptk3,rand,random,rl,readline}]
                 [--timings]
                 [script-file] ...

Assistant: a clever shell implementation

positional arguments:
  script-file           If present, execute the script in script-file or (if
                        not present) execute as a command and exit.
  args                  Additional arguments to the script (or command)
                        specified by script-file.

optional arguments:
  -h, --help            Show help and exit.
  -V, --version         Show version information and exit.
  -c COMMAND            Run a single command and exit.
  -i, --interactive     Force running in interactive mode.
  -l, --login           Run as a login shell.
  --rc RC [RC ...]      RC files to load.
  --no-rc               Do not load any rc files.
  --no-script-cache     Do not cache scripts as they are run.
  --cache-everything    Use a cache, even for interactive commands.
  -D ITEM               Define an environment variable, in the form of
                        -DNAME=VAL. May be used many times.
  --shell-type {b,best,d,dumb,ptk,ptk1,ptk2,prompt-toolkit,prompt_toolkit,prompt-toolkit1,prompt-toolkit2,prompt-toolkit3,prompt_toolkit3,ptk3,rand,random,rl,readline}
                        What kind of shell should be used. Possible options:
                        readline, prompt_toolkit, random. Warning! If set this
                        overrides $SHELL_TYPE variable.
  --timings             Prints timing information before the prompt is shown.
                        This is useful while tracking down performance issues
                        and investigating startup times.


❯ assistant Hi
Hey, how are you today?

❯ assistant -c "what time is it"
The current time is 1:35 p.m.

❯ assistant -i -l --no-rc --no-script-cache -DPATH="PATH:/share/assistant/" assistant script.nlp

Examples

The examples below are produced in interactive mode.

Jaques à dit: répond

❯ echo Hello
Hello
❯ say Hello World # This requires say to be installed
Hello World
❯ Hi Assistant.
Hello $USERNAME.

Navigate files

❯ Where am I
You are at home.
❯ Open Documents
You are now in the Documents directory inside home.
❯ What do we have here?
Listing the current working directory.
...

Get to the bottom of things

Using WebSearch domain, you can get pretty meaningful answers.

❯ How many moons does Saturn have?
I'll need a moment.
❯ Take your time.
I think I have found the answer to how many moons Saturn has.
Saturn has 83 moons.
❯ How old is the universe?
Give me a moment.
I know how old the universe is.
The universe is 13.7 billion years old.

Exit the session

To exit the current session, you can type pretty much anything. As long as Assistant can reasonnably understand your intent.

i.e. :

❯ exit
❯ Q
❯ :q
❯ quit
❯ stop()
❯ terminate
❯ This conversation is over.
❯ Stop this session.

Using voice

Text-To-Speech

Assistant can talk. Just install say and authorize the system to speak. Make sure the service is running and Assistant should be able to connect to it.

Within an interactve session with Assistant, you can toggle TTS using either:

  • the Interface menu,
  • the keyboard shortcut [Ctrl] + [S]
  • Assistant by authorizing it to speak (e.g. assistant you can speak now).
assistant say Hello World and welcome to everyone.

Speech-To-Text

Assistant can also understand when you talk. Just install listen and authorize the system to listen. Make sure listen.service, assistant.service and assistant.listen.service are enabled for Assistant to be able to pick up what you say.

By default, neither the accoustic model nor the language model are ajusted for Assistant, so it's a good idea to at least create a custom scorer using the STT Training Wizard.

trainer=~/.assistant/trainers/stt.train
git archive --remote=git@gitlab.com:waser-technologies/models/en/stt.git HEAD | tar xvf - model.train
mv model.train $trainer
chmod +x $trainer
zsh $trainer

Use Assistant as your default shell

This is not recommended in alpha!

You sould be able to add the location of assistant at the end of /etc/shells. You'll then be able to set Assistant as your default shell using chsh.

sudo sh -c 'w=$(which assistant); echo $w >> /etc/shells'
chsh -s $(which assistant)

Log out and when you come back, Assistant will be your default shell.
