Python 3.x AttributeError:模块“tensorflow.python.keras.api.\u v2.keras.backend”没有属性“set\u image\u dim\u ordering”

最近，我尝试使用python在github中运行代码。代码位于： 我使用了以下软件

TensorFlow-gpu-2.0-beta1 Keras:2.2.4 操作系统：Windows 10 python:3.5 CUDA:10.0 cuDNN:10.0

我在网上遇到了一些人已经提出的同样的问题。即: AttributeError:模块“tensorflow”没有属性“get\u default\u graph” 在我尝试更改代码后，如下所示

从keras导入后端

改为：

从tensorflow.keras导入后端

我遇到了另一个问题。即: AttributeError:模块“tensorflow.python.keras.api.\u v2.keras.backend”没有属性“set\u image\u dim\u ordering”

我不知道现在该怎么办

您在导入中混合了tf.keras和keras，它们不兼容，而且keras目前不支持tensorflow 2.0，尚未发布稳定版本

---

如果必须使用tensorflow 2.0，则必须使用该版本中包含的tf.keras。如果你想使用keras，那么你需要降级到一个稳定的tensorflow版本。

如果我的tensorflow 2.0.0-alpha0版本没有keras怎么办？@OmarCusmaFait你是什么意思，没有keras AFAIK就没有版本了。你可能会有一个坏版本。
