ValueError:获取参数< tf.Operation'init_8'type = NoOp>不能解释为张量. [英] ValueError: Fetch argument <tf.Operation 'init_8' type=NoOp> cannot be interpreted as a Tensor.

问题描述

我正在使用Keras库，只是在尝试初始化VGG16模型，而且我收到关于所有输入不是该图元素的错误.我正在使用Tensorflow后端.

I'm working with the Keras library and I'm simply trying to initialize the VGG16 model, and I'm getting an error about all the inputs not being an element of this graph. I am using a Tensorflow backend.

输入:

from keras.applications.vgg16 import VGG16

model = VGG16()

输出:

推荐答案

我拉开了VGG16代码，文档提到了

I pulled open the VGG16 code and the docs mentioned having

"image_data_format":"channels_last"

"image_data_format": "channels_last"

包含在keras配置JSON文件中.添加似乎可以解决问题.

included in the keras config JSON file. Adding that seemed to fix the problem.

不确定与以下内容之间的区别:

Not sure the difference between that and:

"image_dim_ordering":"tf"

"image_dim_ordering": "tf"

但两者似乎都起作用.
