我正在尝试运行这段代码,但是遇到了以下错误:
Traceback (most recent call last):
File "classifier_from_little_data_script_3.py", line 39, in <module>
from keras import applications
File "C:\Python35\lib\site-packages\keras\__init__.py", line 3, in <module>
from . import activations
File "C:\Python35\lib\site-packages\keras\activations.py", line 3, in <module>
from . import backend as K
File "C:\Python35\lib\site-packages\keras\backend\__init__.py", line 36, in <module>
assert _backend in {'theano', 'tensorflow'}
AssertionError
我尝试找出这个错误的原因,但找不到解决方法。我该如何修复这个问题? 编辑1 这是
keras.json
文件:{
"image_dim_ordering": "tf",
"epsilon": 1e-07,
"floatx": "float32",
"backend": "tf"
}
编辑 2
我已将后端更改为tensorflow
,但遇到以下错误:
ValueError: The shape of the input to "Flatten" is not fully defined (got (None, None, 512). Make sure to pass a complete "input_shape" or "batch_input_shape" argument to the first layer in your model.
我已经为第二次编辑添加了一个单独的问题,在这里。
谢谢。
