asp.net framework mvc machine learning Error = Microsoft.ML.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=************

Question

当我将机器学习添加到我的项目并校准模型时，我收到此错误，但我不知道为什么

我调用该模型的索引函数

public async Task<ActionResult> Index()
        {
        
         *this 2 lines gives that error*
            var input = new ModelInput();
            ModelOutput result = ConsumeModel.Predict(input);

         








            ViewBag.halo = User.Identity.GetUserId();
           

            var productsModels = db.ProductsModels.Include(p => p.categorieId).Where(p => p.users.Id == null);

            return View(await productsModels.ToListAsync());
        }
