Tutorial on how to build simple discord chat bot using discord.py and DialoGPT.

Discord interactive chat bot assembled using discord.py and DialoGPT.

Requirements:

• Ubuntu terminal
• Discord account
• At least 2GB of RAM to run DialoGPT-small model, more if using larger model

Installation of dependencies:

In Ubuntu terminal run following commands.

$ sudo apt-get update
$ sudo apt-get install python3-pip libffi-dev libnacl-dev python3-dev

Change root password (if you know what it is ignore this step).

$ passwd 

Create user from which you are going to run bot to not run bot as root.

$ sudo adduser bot
$ su - bot
$ pip3 install -U torch==1.4.0+cpu torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html
$ pip3 install -U discord.py
$ pip3 install -U transformers

Alternatively if installation doesn't work follow instructions from:

• On pytorch.org/get-started/locally/ you can even choose which operating system you are going to use and it will show command to run.
• There is how to install and run first quick example in README file on github.com/Rapptz/discord.py
• On github.com/microsoft/DialoGPT you can find out how to train models and install dependencies
