我是机器学习的新手,它是通过ML.NET进行的。最近我发现自己陷入了黑洞,请帮忙:D 记录的错误是“找不到标签列“标签”(参数“ inputSchema”)”。 它所在的代码是:
var dataProcessPipeline = mlContext.Transforms.Text.FeaturizeText(outputColumnName: "userIdFeaturized", inputColumnName: nameof(MovieRating.UserId))
.Append(mlContext.Transforms.Text.FeaturizeText(outputColumnName: "movieIdFeaturized", inputColumnName: nameof(MovieRating.MovieId)))
.Append(mlContext.Transforms.Concatenate("Features", "userIdFeaturized", "movieIdFeaturized"));
我在哪里犯错?
