tensorflow - 运行 object_detection_tutorial 时出现问题 TypeError : load() missing 2 required positional arguments

Question

我对 tensorflow 还很陌生，我正在尝试运行object_detection_tutorial。我遇到 TypeError，但不知道如何修复它。

这是 load_model 函数，缺少 2 个参数:

tags:一组字符串标签，用于标识所需的 MetaGraphDef。这些应该与使用 SavedModel save() API 保存变量时使用的标签相对应。

export_dir:SavedModel Protocol Buffer 和要加载的变量所在目录。

def load_model(model_name):
  base_url = 'http://download.tensorflow.org/models/object_detection/'
  model_file = model_name + '.tar.gz'
  model_dir = tf.keras.utils.get_file(
    fname=model_name, 
    origin=base_url + model_file,
    untar=True)

  model_dir = pathlib.Path(model_dir)/"saved_model"

  model = tf.saved_model.load(str(model_dir))
  model = model.signatures['serving_default']

  return model

你能帮我解决这个问题并运行我的第一个对象检测器吗:D？

我遇到了同样的问题，我正在尝试解决这个问题 1 周。我想解决方案应该是这样的；

model = tf.compat.v2.saved_model.load(str(model_dir), None)

更多详细信息(来自official website)；

从export_dir加载SavedModel。

tf.saved_model.load(
    export_dir,
    tags=None
)

别名:

tf.compat.v1.saved_model.load_v2

tf.compat.v2.saved_model.load
