Я новичок в объекте-обнаружения-API, успешно установил API,
python object_detection_tutorial.ipynb работал нормально.
но когда последовал этот урок , я получаю ValueError из tenorflow / python / module / module.py
- это руководство ,
iv'e удалось сделать все до последнего шага "модель тренинга",
чем когда я запускаю эту команду:
python model_main.py --logtostderr --train_dir=training/ --pipeline_config_path=training/faster_rcnn_inception_v2_pets.config
(все пути верны)
Я получаю эту ошибку:
ValueError:
Constructing a tf.Module without calling the super constructor is not supported. Add the following as the first line in your __init__ method:
super(FasterRCNNMetaArch, self).__init__()
Я не нашел никакой помощи в этом, я попробовал новую установку API обнаружения объектов, но не помог.
У меня та же ошибка, после этого models / research / object_detection / g3doc / installation.md учебник.
При попытке запустить:
python object_detection/builders/model_builder_test.py
Я ожидал, что модель начнет свою работу, как в учебнике.
но получил это вместо:
/ home / gal.

ValueError: Constructing a tf.Module without calling the super constructor is not supported. Add the following as the first line in your __init__ method:
super(FasterRCNNMetaArch, self).__init__()
После некоторых раскопок я обнаружил, что в:
/TensorFlow/models/research/object_detection/meta_architectures/faster_rcnn_meta_arch.py
В строке 466:
super(FasterRCNNMetaArch, self).__init__(num_classes=num_classes)
так что, возможно, это не так.
После некоторой точки останова iv'e foune, которая в строке 97 ('finally') в:
/home/gal/.virtualenvs/dl4cv/lib/python3.6/site-packages/tensorflow/python/module/module.py
есть эта часть, которая вызывает ValueError:
finally:
# The base Module constructor enters the modules name scope before
# returning such that other functionality in the ctor happens within the
# modules name scope.
scope = getattr(module, "_ctor_name_scope", None)
exc_info = sys.exc_info()
if scope is None:
if exc_info[0] is None:
raise ValueError(
"Constructing a tf.Module without calling the super constructor "
"is not supported. Add the following as the first line in your "
"__init__ method:\n\n"
"super(%s, self).__init__()" % cls.__name__)
else:
scope.__exit__(*exc_info)
del module._ctor_name_scope
Когда я бегу, scope - это None, а также exc_info[0] - это Нет.
Есть идеи?
спасибо
