1-介绍
1，keras需要在TensorFlow之上才能运行，所以要先安装tensorflow.
2,Tensorflow只能在3.7以前的python版本中运行，所以需要先创建一个基于python 3.6的虚拟环境.
2-创建虚拟环境
打开anaconda prompt,输入命令：
#创建虚拟环境名
conda create -n tensorflow_py36 python=3.6
#查看已创建环境
conda info --envs
#激活到创建的环境中去
conda activate tensorflow_py36
结果图如下：
3-tensorflow与keras安装
keras搭建在tensorflow基础上，在安装keras安装之前需要安装tensorflow、numpy、matplotlib、scipy。
conda install numpy
conda install matplotlib
conda install scipy
conda install tensorflow
conda install keras
然后验证是否安装成功,在anaconda prompt中输入以下指令：
python
import keras
出现如下图所示既安装成功。
4-错误记录-等待解决
在安装的过程中出现了以下情况，等待后续的解决。但是我在pycharm中可以使用keras。
