最近，我尝试用python在github中运行一段代码，代码位于：https://github.com/costapt/vess2ret和我使用了以下软件
操作系统： windows 10 Python：3.5 CUDA：10.0 CUDNN：10.0
我遇到了同样的问题已经显示了一些人在网上。那就是：属性错误：模块'tensorflow'没有属性'get_default_graph'在我尝试将代码更改为以下内容后
从keras导入后端
更改为：
从tensorflow.keras导入后端
我遇到了另一个问题.那就是：属性错误：模块'tensorflow.python.keras.api._v2.keras.backend'没有属性'set_image_dim_ordering'
我不知道现在该怎么办
