    var parquetAssembly = Assembly.Load("Microsoft.ML.Parquet");
    var parquetLoarderType = parquetAssembly.GetType("Microsoft.ML.Data.ParquetLoader");

    var methods = parquetLoarderType.GetConstructor(new[] { typeof(IHostEnvironment), parquetArgsType, typeof(string) });
    var p = methods.Invoke(new object[] { ctx, parquetArgsType.GetConstructors()[0].Invoke(null), path });
