Resolved Unity does not recognise MLAgents namespace

Hello,
Im making a 2D game and trying to set up some agents, so I installed ML Agents using the package manager, but when I try to make the agent scripts I keep getting the error
Assets/PlaneAI.cs(4,7): error CS0246: The type or namespace name 'MLAgents' could not be found (are you missing a using directive or an assembly reference?
Anyone know whats going wrong?

 

using Unity.MLAgents;

 

Thank you Ive been stuck on that for ages

 

I have this and I am still getting the error in console. Any advice? Thanks

@betike What's the full error message? Did you follow the instructions here to install it from the pacakge manager? https://github.com/Unity-Technologi...d#install-the-comunityml-agents-unity-package

 

it was a path issue,its working now thanks

 

How do you fix the Path issue? I met the same error: Assets\ML-Agents\Examples\Template\Scripts\TemplateAgent.cs(3,22): error CS0234: The type or namespace name 'Actuators' does not exist in the namespace 'Unity.MLAgents' (are you missing an assembly reference?)

 

Main problem is that current version of "ML-Agents package" in Unity doesn't include "ML-Agents Extensions" which is used in example project
To fix this:
First instal Package from Unity Manager
Then you have to download current release version from git
After it you got 2 ways to install needed package:
1. Instal using link to github
In the Package Manager hit the "+" button, and select "Add package from git URL" (<- This one wont solve problem at the moment cause git owner has to accept your request)
Place there:
git+https://github.com/Unity-Technologies/ml-agents.git?path=com.unity.ml-agents.extensions
Or in the your manifest.json file located in Project -> Packages add next line below "com.unity.ml-agents":
"com.unity.ml-agents.extensions": "git+https://github.com/Unity-Technologies/ml-agents.git?path=com.unity.ml-agents.extensions",
2. Local Instalation
In the Package Manager hit the "+" button, and select "Add package from disk"
Find "com.unity.ml-agents" in downloaded repo
Select "package.json"
Then same steps but with "com.unity.ml-agents.extensions" folder
(After it you also may spot "UnityEditor.AsyncHTTPClientone(State, Int32)" error, it easily fixes by disabeling Edit -> Preferences -> Show Asset Store Search Hits )

 

It works by me! Thank you so much!

 

i have done both of the methods, but still get the same error. How?

 

I am also experiencing the same issue, every video that I watch does not address this. When I open up any of the example scrips from "Project" none of the ML Agent packages are being imported so the code doesn't light up with any information.

 

Hi @Kingsmen99,
I saw your post in the other thread. Can you provide more information like:

• what operating system are you on and what version
• what version of unity are you using
• what code editor are you using
• any other additional information about your installation process

It is easier to diagnose issues like this with more information.
Cheers,
Chris
