我正在使用RobotFlow检测图像，但这是一个错误

我使用的系统要求： Ubuntu 20.04 张量流2 ssd_mobilenet_v2_fpnlite_640x640_coco17_tpu-8

命令代码我遇到了错误：

import pathlib

filenames = list(pathlib.Path(work_dir + '/training/').glob('*.index'))

filenames.sort()
print(filenames)

#recover our saved model
pipeline_config = pipeline_file
#generally you want to put the last ckpt from training in here
model_dir = str(filenames[-1]).replace('.index','')
configs = config_util.get_configs_from_pipeline_file(pipeline_config)
model_config = configs['model']
detection_model = model_builder.build(
      model_config=model_config, is_training=False)

# Restore checkpoint
ckpt = tf.compat.v2.train.Checkpoint(
      model=detection_model)
ckpt.restore(os.path.join(str(filenames[-1]).replace('.index','')))


def get_model_detection_function(model):
  """Get a tf.function for detection."""

  @tf.function
  def detect_fn(image):
    """Detect objects in image."""

    image, shapes = model.preprocess(image)
    prediction_dict = model.predict(image, shapes)
    detections = model.postprocess(prediction_dict, shapes)

    return detections, prediction_dict, tf.reshape(shapes, [-1])

  return detect_fn

detect_fn = get_model_detection_function(detection_model)
