Question

我正在使用web.py创建一个简单的Web应用程序。目前，我陷入了要在我的类中创建ResNet50实例的问题。我正在使用tensorflow作为后端（版本1.10.0）的keras版本2.2.2。 Python 3.6版（由Anaconda3提供）。我正在运行Slackware 14.2 x86_64。

抛出该异常的代码部分：

class Nets:
@classmethod
def Resnet_dog_detector_CNN(cls):
    with graph.as_default():
        cls.ResNet50_model = ResNet50()

Nets类是全局类。如您所见，我什至没有尝试使用模型->不是试图加载一些预定义的权重。

完整的错误是：

我已经用谷歌搜索了，但是我发现的解决方案需要直接处理张量流。就我而言，我将其用作Keras的后端。

另一件事，如果我从webpy中运行该代码（即直接在python中），则不会收到该错误（仍然是tensorflow作为keras的后端）。

外面有没有想给我提示的专家？预先感谢。
