在 https://keras-zh.readthedocs.io/applications/ 给出了keras applications 中的一些预训练模型,部分包导入方式应为:
import keras_applications
mod =keras_applications.resnet.ResNet101(include_top=True,
weights=None,
input_shape=(224,224,3),
)
此时会出现如题错误:
data_format=backend.image_data_format(), AttributeError: 'NoneType' object has no attribute 'image_data_format'
改正方法,代码添加四行修改为:
mod = keras_applications.resnet.ResNet101(include_top=True,
weights=None,
input_shape=(224, 224, 3),
backend=keras.backend,
layers=keras.layers,
models=keras.models,
utils=keras.utils
)
./Anaconda3/Lib/site-packages/keras/applications/resnet50.py
.:/Anaconda3/Lib/site-packages/keras/applications/init.py
keras.applications.resnet50在构建实例的时候调用了装饰器keras_modules_injection
,给keras_applications
相关类增加参数。
