    Hello to everyone!
    I followed the instructions for installing ml-agents.
    Εverything was going well until I realized that at in Unity 2018.2, in Package Manager there is not the option of the button ' + ', to install the package.json from com.unity.ml-agents.
    I've been searching a lot for the solution. I wouldn't prefer not to install a newer version because I will miss out data.
    Is there any way to find a solution?
    Thank you in advance!!!

    Hi @dani_kal,
    We support 2018.4 and later. If you upgrade to 2018.4, you should not have to worry about any data being lost, and should be able to install the ML-Agents package locally.

    If you can make a backup of your project, and then attempt the upgrade, this should be a safe test to ensure you don't lose your data.
