Cannot import name 'tf_utils' when using importing keras
提问by Christophorus Reyhan
I'm using Oracle Linux 7.7, and I installed python3.6 using yum (epel repos). Then I install tensorflow 1.5(since if it goes newer ver I got core dumped) and keras. If I'm importing tensorflow, I got nothing. But when I import keras, I got
我使用的是 Oracle Linux 7.7，我使用 yum (epel repos) 安装了 python3.6。然后我安装 tensorflow 1.5（因为如果它更新了，我得到了核心转储）和 keras。如果我要导入 tensorflow，我什么也得不到。但是当我导入 keras 时，我得到了
ImportError: cannot import name 'tf_utils'
Here's the full output:

I was using python 3.6 by building it from source before and keras worked fine but since I can't install tkinter for pyplot I uninstall it and using the one from yum instead.
我之前通过从源代码构建它来使用 python 3.6，并且 keras 工作正常，但是由于我无法为 pyplot 安装 tkinter，我将其卸载并使用 yum 中的那个。

Seems like it was a problem with keras 2.3.0, I installed keras 2.1.5 using pip and it works fine.
似乎是 keras 2.3.0 的问题，我使用 pip 安装了 keras 2.1.5 并且工作正常。

I had the same problem, but upgraded Tensorflow via pip rather than downgrading Keras and this solved the problem :)
我遇到了同样的问题，但是通过 pip 升级了 Tensorflow 而不是降级 Keras，这解决了问题:)
Using Python 3.6.4, Keras 2.3.1, Tensorflow 2.0
使用 Python 3.6.4、Keras 2.3.1、Tensorflow 2.0
