我正在运行图像分类器，但它不断产生错误
Keras loaded from keras Python module v1.2.0, however version 2.0.0 is required. Please update the keras Python package. Error in py_call_impl(callable, dots$args, dots$keywords) : TypeError: init() got an unexpected keyword argument 'data_format'
Keras 从 keras Python 模块 v1.2.0 加载，但需要 2.0.0 版。请更新 keras Python 包。py_call_impl(callable, dots$args, dots$keywords) 中的错误：TypeError: init() 得到了一个意外的关键字参数“data_format”
I have tried to remove and re-install keras through using python command "pip install keras --upgrade"and also through R using "install.packages("keras")" but all in vain.
我试图通过使用 python 命令“pip install keras --upgrade”以及通过 R 使用“ install.packages(“keras”)”来删除和重新安装 keras，但都是徒劳的。

I will suggest you to use python anaconda. you will get less errors and most of them can be easily solved.
我会建议你使用 python anaconda。你会得到更少的错误，其中大部分都可以轻松解决。
here by looking image that you shared, it looks like problem is with versions of bleach, html5lib and google-gax, reinstall these dependencies.
在这里通过查看您共享的图像，问题似乎出在漂白、html5lib 和 google-gax 版本上，请重新安装这些依赖项。

I guess the solution was just bits from all the answers suggested down. So in this, I'm putting it all together.
我想解决方案只是从所有建议的答案中提取出来的。因此，在此，我将所有内容放在一起。
I solved the problem by removing "Keras", "Keras-Applications" & "Keras-Preprocessing" from python as well as "Keras-2.1.6" from R.
我通过从 python 中删除“Keras”、“Keras-Applications”和“Keras-Preprocessing”以及从 R 中删除“Keras-2.1.6”解决了这个问题。
I then re-installed "Keras" by pip install Keras==2.0.0then re-installed "Keras" in R also.
然后我通过pip install Keras==2.0.0重新安装了“Keras”，然后也在 R 中重新安装了“Keras”。
Now it runs perfectly.
现在它运行完美。
