module 'tensorflow' has no attribute 'keras'

安装好tensorflowjs后报错

   因为自己之前一直是使用tf2.0，而tensorflowjs使用不了2.0，而且记得命名手动删去site-packages下的tensorflow后，安装的tensorflowjs-1.3.2的，而且显示安装是成功了的，因为tensorflowjs-1.3.2依赖的是tensorflow1.15的，但是运行上面代码出了问题，问题实际上是自己配置的pip豆瓣源，所以以前存留了tensorflow2.0的安装文件。

我发现根本现在使用的不是1.15而是2.0的，而且连import tensorflowjs都不成功的

解决方式，是在pip安装的文件下，删了tensorflow的所有文件，重新打开即可，一般来说pip源安装好的文件在：

C:\Users\Administrator\AppData\Roaming\Python\Python35\site-packages

现在就能执行成功了
