    Hi
    I'm using Python version 3.9.4 (with pip 21.1.1 and torch 1.7.1). As suggested on Unitys homepage (https://github.com/Unity-Technologies/ml-agents/tree/latest_release/ml-agents-envs), I am using mlagents 0.26.0. When I have trained a "brain", I can not import the onnx-file into Unity. I get this error messags:
    Asset import failed, "Assets/Models/AUV Behavior.onnx" > OnnxImportException: Unexpected error while parsing layer 18 of type Gemm. Hope anyone can help.

    Kind regards,
    Stig

    Im not sure. The ml-agents is 0.26.0. But that is not what you are asking about? I am using Visual Studio Version 16.7.7.

    In Unity, you should be able to see the version of the com.unity.ml-agents c# package
