data_format=backend.image_data_format(), AttributeError: 'str' object has no attribute 'image_data_format'

这个新的错误提示表明之前试图访问的 `backend.image_data_format()` 返回了一个字符串而不是 `NoneType`,而这个函数应该返回的是一个用于设置图像数据维度顺序的对象。看起来你可能在一个已经硬编码或者静态赋值为字符串的地方尝试去调用这个函数。
例如,如果你直接像下面这样做:
```python
data_format = "channels_last" # 这里data_format是一个字符串,不是backend实例
resnet_model = ResNet50(weights='imagenet', include_top=False, pooling='avg', data_format=data_format)
```
在这种情况下,你应该在创建模型之前获取正确的backend实例并调用相应的方法,如:
```python
if backend.backend() == "tensorflow":
backend.set_image_data_format("channels_last")
elif backend.backend() == "theano":
# 对于Theano,这里可能有不同的方法,需要查阅文档
else:
raise ValueError("Unsupported backend")
resnet_model = ResNet50(weights='imagenet', include_top=False, pooling='avg')
```
相关问题
data_format=backend.image_data_format()
这是一个 Python 代码片段,用于获取当前 Keras 后端的图像数据格式。在 Keras 中,有两种可用的图像数据格式,分别是 "channels_last" 和 "channels_first"。该代码片段中,使用了 backend.image_data_format() 函数来获取当前使用的数据格式,并将结果赋值给变量 data_format。
AttributeError: 'function' object has no attribute 'image_data_format'
This error occurs when trying to access the `image_data_format` attribute of a function object, which is not defined for functions.
Most likely, this error is caused by trying to access the `image_data_format` attribute of a function instead of a Keras backend object. Make sure you are using the correct object and that it has the `image_data_format` attribute defined.
For example, instead of using a function like `keras.backend.function()`, try using `keras.backend` directly to access the backend object and its attributes:
```
from keras import backend as K
print(K.image_data_format())
```
