keras blog에 대한 자세한 게시물이 있습니다.
그러나 다음과 같이 내가 오류를 얻을 때 코드를 컴파일 : 나는 dim_ordering='th'을 설정할 때
keras 및 tensorflow를 백엔드로 사용하여 회선 신경망에 입력 시각화
Using TensorFlow backend.

이 오류는 간다.
그러나 tensorflow 백엔드를 사용할 때 차원 순서는 dim_ordering='tf'이어야합니다. 다음과 같이 vgg16_weights.h5에서 loading weights 동안
심지어 '일'로 dim_ordering을 설정 한 후, 나는 오류 : '일'과 'TF'에 대한 this post에서
Traceback (most recent call last):
File "visulaize_cifar.py", line 67, in <module>
model.layers[k].set_weights(weights)

'provided weight shape ' + str(w.shape))
ValueError: Layer weight shape (3, 3, 128, 64) not compatible with provided weight shape (64, 3, 3, 3).
상세한.
위의 오류는 레이어 가중치가 'tf'에 있음을 의미합니다 (그러나 첫 번째 오류가 발생하지 않도록 'th'로 설정 함). 'th'순서로 가중치 모양을 제공합니다.
What seems to be the error?
