I saw this 2 months ago and finally had the time to not just watch but follow along and can I just say again, this is perfection. MLAgents always seemed to clunky / obtuse to use, but this made it straight forward. This tutorial took me straight through and I am amazed at what I was able to train on and get done. This just opens up a world of possibilities I can't wait to dive into, thanks again for this amazing tutorial!

Quick Tip: In windows explorer, in the folder you want in cmd, just type cmd in the address bar. it will open cmd.exe to that folder

Our graduation project is with Unity ML Agents and this video helped me to get the basics. Thank you!

Awesome work, thank you so much man !

For people joining the bandwagon around July/August 2022 :

- Take the ML-Agents package manager version 2.2.1-exp.1 (at least)
- When launching Tensorboard, don't hesitate to give the folder where the results are in the command you type (ex: logdir=C:/user/MLProject/results), instead of typing "results"
- If you know your way around the Python environment, feel free to use Anaconda, works just as good

(I'll update this comment if I find any other stuff that changed since)

Hi from 2023! I had some trouble instaling the python enviroment but I made it work.
Unity: 2022.3.14f1
Python 3.9.13

Before venv:
py -3.9 -m venv venv

After venv:
python -m pip install --upgrade pip
pip install mlagents
pip3 install torch torchvision torchaudio
pip install protobuf==3.20.3
pip install packaging

Works fine! Hope so u too :D

After a few days of following your tutorial little by little (sorry I'm still a newbie), , finally I can understand what you teach, even though there are many changes to the ML-Agents.. but thank you so much Mr.hugo for the knowledge this is very useful for me curious about machine learning.
