Have some nectar
I run this toturial in Jan 2024. I encountered some challenges due to the recent library upgrades, which didn't align with the tutorial. I used Unity 2019.4 along with ML-Agents 2.0.1 package. In my Anaconda environment, I cloned ML-Agents from GitHub and followed the GitHub documentation to install version 1.0.0. I had to make some modifications to the HummingbirdAgent.cs file, specifically in the OnActionReceived and Heuristic functions. Finally, I updated the YAML files to the latest version, which can be found in <ml-agents-clone>/config/ppo/Basic.yaml, and incorporated some variables from the original YAML files. After these adjustments, I was able to successfully complete the training. I genuinely appreciate the invaluable knowledge you've shared in your video tutorial.
