I want to fix the C# Tensorflow bug

my coding

=========================================================

    MemoryStream ms = new MemoryStream();
                Image img = pictureBox1.Image;
                img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
                TFTensor tensor = ms.ToArray();
                using (var graph = new TFGraph())
                {
                    graph.Import(File.ReadAllBytes(@"C:\Users\User\saved_model.pb"));
                    using (var session = new TFSession(graph))
                    {
                        // Setup the runner
                        var runner = session.GetRunner();
                        //var tensor = ImageUtil.CreateTensorFromImageFile(file);

                        runner.AddInput(graph["input"][0], tensor);
                        runner.Fetch(graph["output"][0]);

                        // Run the model
                        var output = runner.Run();

                        // Fetch the results from output:
                        TFTensor result = output[0];
                    }
                }
