    Hi,
    I am migrating from an older project.
    After I installed ml-agent via package manager do I have to install also Barracuda plugin? Or Barracuda is included in the ml-agent package?
    Is it correct to think that the fact that barracuda has its own package is because I can install without ml-agents and that ml-agents will include barracuda latest realease?
    thanks
    Guido

    If you used the 0.14 version of ML-Agents, you don't have to install the Barracuda package, it is included (it is automatically installed when you install the package.json). However, for earlier version I think that you first need to install the Barracuda package then drag and drop the UnitySDK folder in your Asset directory.

    Yeah, it depends on the version you're on. For 0.12 and below, Barracuda was included in the project. For 0.13.0, you need to install Barracuda from the package manager. For 0.14 (and the future), it will be a dependency of the com.unity.ml-agents package (even though it's only a local package currently).

    Hi, I installed version 0.14 and the update went smooth. So now the project is in Unity 2019.3.2.f1 (latest release)
    all good but I cannot build the project. It says that I miss the google library ???

    btw. can you confirm that I can build for webgl?

    I also tried the exaple project of ml-agents (the 3d ball) and try to build for the web but got the same error .. missing directive google llibrary ??

    Are you able to build for the web?

    thanks
    Guido

    Hi,
    The gRPC library was fixed in the master branch of ML-Agents here and will be available in the next release.
    Cheers,
    Chris

    I don't think this is possible with the Unity Package Manager (it's not specific to Barracuda or ML-Agents).
