如何安装 Infer.NET 到 Unity 2018.3

Question

我有一个新的 Unity 项目并按照 Using .NET 4.x in Unity, i've downloaded Microsoft.ML.Probabilistic.Compiler NuGet package from the gallery 中的说明将 DLL 复制到 Assets/Plugins。之后Unity输出错误信息

Assembly 'Assets/Plugins/Microsoft.ML.Probabilistic.Compiler.dll' will not be loaded due to errors: Unable to resolve reference 'Microsoft.ML.Probabilistic'. Is the assembly missing or incompatible with the current platform?

我下载并复制了丢失的 DLL 和每个后续丢失的 DLL 依赖项

Microsoft.ML.Probabilistic.dll
System.CodeDom.dll
Microsoft.CodeAnalysis.CSharp.dll
Microsoft.CodeAnalysis.dll
System.Collections.Immutable.dll
System.Reflection.Metadata.dll

Unity 在添加 System.Reflection.Metadata.dll 后不再显示错误。

当我添加

using Microsoft.ML.Probabilistic;
using Microsoft.ML.Probabilistic.Compiler;

脚本，该项目在 Unity 和 Visual Studio 社区中构建良好，但是当我尝试使用库时，即 Microsoft.ML.Probabilistic.Compiler.Variable<T> class

using UnityEngine;
using Microsoft.ML.Probabilistic;
using Microsoft.ML.Probabilistic.Compiler;

public class Main : MonoBehaviour {
    void Start () {
        Variable<bool> firstCoin = Variable.Bernoulli (0.5);
    }
}

Unity 和 Visual Studio 都失败了

Assets/Scripts/Main.cs(7,3): error CS0246: The type or namespace name 'Variable<>' could not be found (are you missing a using directive or an assembly reference?)

和

Assets/Scripts/Main.cs(7,30): error CS0103: The name 'Variable' does not exist in the current context

将 -r:Microsoft.ML.Probabilistic.Compiler.dll 添加到 Assets/mcs.rsp 文件会产生错误

Microsoft (R) Visual C# Compiler version 2.9.1.65535 (9d34608e) Copyright (C) Microsoft Corporation. All rights reserved.

error CS0006: Metadata file 'Microsoft.ML.Probabilistic.Compiler.dll' could not be found

项目配置为

统一 2018.3.10f1
Visual Studio Mac 社区
构建 Settings/Platform：iOS
播放器Settings/Scripting 运行时版本：.NET 4.x 等效

设置与否没有区别

播放器 Settings/Api 兼容级别：.NET 4.x

或

播放器Settings/Api兼容级别：.NET Standard 2.0

其他设置保留默认值。

我没有按照指南中的说明将 DLL 添加到 Visual Studio 中的 vs 项目

Visual Studio regenerates .csproj and .sln files for Unity projects each time they're opened. As a result, you cannot add assembly references directly in Visual Studio because they'll be lost upon reopening the project. Instead, a special text file named mcs.rsp must be used:

Create a new text file named mcs.rsp in your Unity project's root Assets directory.

On the first line in the empty text file, enter: -r:System.Net.Http.dll and then save the file. You can replace "System.Net.Http.dll" with any included assembly that might be missing a reference.

Restart the Unity editor.

Answer 1

Variable<bool> 不属于 Probabilistic 或 Probabilistic.Compiler

相反，您需要包括 using Microsoft.ML.Probabilistic.Models;，其中 Variable<T> 是其中的一部分。

using UnityEngine;
using Microsoft.ML.Probabilistic.Models;//we need Probabilistic.Models

public class SomeScript : MonoBehaviour
{
    void Start()
    {
        Variable<bool> firstCoin = Variable.Bernoulli(0.5);
    }
}

使用 unity 2018.3 和 2019.1 进行了测试，均使用 .net 4.x 运行时，并且构建良好（尽管在 Windows 上应该没有什么区别）。

... and copied the DLL to Assets/Plugins. After this Unity outputs an error message

我个人不必为了让它工作而这样做。我使用 Install-Package Microsoft.ML.Probabilistic.Compiler -Version 0.3.1810.501 从 NuGet 直接将包下载到默认目录 (project/Packages/)。它也不需要我下载任何额外的 DLL。
