python - 属性错误: module 'tensorflow.python.keras.backend' has no attribute 'get_graph'

Question

我一直在研究用于对象检测的 keras yolov3 模型。此错误不断出现。这是错误:

AttributeError: module 'tensorflow.python.keras.backend' has no attribute 'get_graph'

我不知道该怎么办。我尝试将“import keras.module.module”替换为“tensorflow.keras.module.module”。但还是不行。

完整输出代码:

Using TensorFlow backend.

我的导入:

import numpy as np
from tensorflow.keras.layers import Conv2D, Input, BatchNormalization, LeakyReLU, ZeroPadding2D, UpSampling2D
from keras.layers.merge import add, concatenate
from tensorflow.keras.models import Model
import struct
import cv2
import imageio

项目“用于对象检测的YOLOv3模型”存在一些版本问题。我遇到了同样的问题，我使用了tensorflow 1.14.0和keras 2.2.0。

只需覆盖特定版本即可。在命令行中写入。

pip install tensorflow==1.14.0
pip install keras==2.2.0
