how to set python dll path? #1684

    string pythonPath1 = @"/-/opt/anaconda3/bin/python3.9";
    string pythonPath2 = @"/-/opt/anaconda3/lib/python3.9/site-packages";
    Environment.SetEnvironmentVariable("PATH", pythonPath1, EnvironmentVariableTarget.Process);

    Environment.SetEnvironmentVariable("PYTHONPATH", pythonPath2, EnvironmentVariableTarget.Process);
    Environment.SetEnvironmentVariable("PYTHONNET_PYDLL", @"/-/opt/anaconda3/lib/libpython3.9.dylib");    

    using (Py.GIL())

            double c = np.cos(5) + sin(5);
            Debug.Log(c);
