使用导入Keras时无法导入名称'tf_utils'

Question

我正在使用Oracle Linux 7.7，并且使用yum（epel仓库）安装了python3.6。然后我安装了tensorflow 1.5（因为如果它更新了，我会丢弃内核）和keras。如果我导入tensorflow，我什么也没有。但是当我进口喀拉拉邦时，我得到了

ImportError: cannot import name 'tf_utils'

这是完整的输出：

$ python

我以前通过从源代码构建它来使用python 3.6，而keras可以正常工作，但是由于我无法为pyplot安装tkinter，因此我将其卸载并使用yum中的一个。

好像是keras 2.3.0的问题，我使用pip安装了keras 2.1.5，它工作正常。
