下面的代码生成了常规的 tensorflow 模型，但是当我尝试将其转换为 tensorflow lite 时它不起作用，我遵循了以下文档。

https://www.tensorflow.org/tutorials/estimator/linear 1 https://www.tensorflow.org/lite/guide/get_started

export_dir = "tmp"
serving_input_fn = tf.estimator.export.build_parsing_serving_input_receiver_fn(
  tf.feature_column.make_parse_example_spec(feat_cols))

estimator.export_saved_model(export_dir, serving_input_fn)

# Convert the model.
converter = tf.lite.TFLiteConverter.from_saved_model("tmp/1571728920/saved_model.pb")
tflite_model = converter.convert()

错误信息

Traceback (most recent call last):
  File "C:/Users/Dacorie Smith/PycharmProjects/JamaicaClassOneNotifableModels/ClassOneModels.py", line 208, in <module>
    tflite_model = converter.convert()

我已实现以下代码来上传文件.该文件将上载到该位置("../App_Data/uploads"),但它不会显示在项目中.我必须在项目中手动包含该文件.为什么文件没有显示？

 public ActionResult ChangeSetting(SettingViewModel setting)
    {
        string userId = User.Identity.GetUserId();
        ApplicationUser currentUser = this._appUserRepo.Find(e => e.Id.Equals(userId)).FirstOrDefault();

        if (setting.PictureUrl != null)
        {
            if (setting.PictureUrl.ContentLength > 0)
            {
                string fileName = Path.GetFileName(setting.PictureUrl.FileName);
                if (fileName != null)
                {

                    string path = Path.Combine(Server.MapPath("../App_Data/uploads"), fileName);
                    setting.PictureUrl.SaveAs(path);
                    if (currentUser != null)
                    {
                        currentUser.PictureUrl = path;
                        currentUser.PictureSmalUrl = path;
                        currentUser.PictureBigUrl = path;
                    }
                }
            }
        }
        if (setting.FirstName != null)
        {
            if (currentUser != null) currentUser.FirstName = setting.FirstName;
        }           
        _appUserRepo.Update(currentUser);
        return RedirectToAction("index", "Admin");
    }
