Python3.6.5安装Keras

Pyhton3.6.5 安装Keras之旅-成功

首先要先安装好tensorflow，安装过程：https://blog.csdn.net/weixin_52500860/article/details/115839580

1. 打开Anaconda prompt
   
   没有anaconda也需要提前安装哦！
2. 激活tensorflow
   命令：activate tensorflow
   
3. conda install mingw libpython
   
   pip install theano
   
4. 上面步骤完成之后不要直接：pip install keras，即使安装成功也会出现错误：把keras降到2.2，依然错误：
   版本不匹配

成功示范：
pip install keras==2.3.1 -i https://pypi.douban.com/simple
安装成功：

5. 验证是否有效
   命令：python
   import keras
   
   错误解决：
   1.安装keras，tensorflow时出现的错误：
   ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
   tensorflow 2.0.0 requires keras-applications>=1.0.8, but you have keras-applications 1.0.2 which is incompatible.
   tensorflow 2.0.0 requires keras-preprocessing>=1.0.5, but you have keras-preprocessing 1.0.1 which is incompatible

解决方案：示例：

pip install keras-applications
