如何在keras中使用tensorflow nce_loss？

Question

我正在尝试进行大型多类分类（实际上是翻译）。

我正在尝试在keras中使用tensorflow nce_loss，但无法使其工作。这里有什么帮助吗？

我不知道如何将上一层的权重，num_class和偏差传递给nce_loss。

我收到以下错误：

[HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Edit(EditMatchesViewModel match)
    {

        if (ModelState.IsValid)
        {
            var updatedMatch = db.Matches.Find(match.ID);
            updatedMatch.Date = match.Date;
            updatedMatch.AwayTeam = match.AwayTeam;
            updatedMatch.HomeTeam = match.HomeTeam;
            updatedMatch.Division = match.Division;
            updatedMatch.Games = new List<Game>();

            foreach (var game in match.Games)
            {
                if (game.ID > 0)
                {
                    var updatedGame = db.Games.Find(game.ID);
                    updatedGame.GameType = db.GameType.Find(game.GameType.ID);
                    updatedGame.AwayPlayer1 = db.Users.Find(game.AwayPlayer1.Id);

                    updatedGame.HomePlayer2 = db.Users.Find(game.HomePlayer2.Id);
                    updatedGame.AwayScore1 = game.AwayScore1;
                    updatedGame.AwayScore2 = game.AwayScore2;
                    updatedGame.HomeScore1 = game.HomeScore1;
                    updatedGame.HomeScore2 = game.HomeScore2;

                    updatedMatch.Games.Add(updatedGame);
                }
            }
            db.Matches.Attach(updatedMatch);
            db.Entry(updatedMatch).State = EntityState.Modified;
            await db.SaveChangesAsync();

            return RedirectToAction("Index");
        }
        return View(match);
    }
