重装Python 、Anaconda、Pycharm、Pytorch 1.0.0 Tensorflow系统：
在安装PyQt库的时候Python2.7与3.6版本不兼容，导致Python运行程序报错：process finished with exit code -1073741819 (0xC0000005) ，重新配置python版本也没作用，只好重装系统。
1，Anaconda 下载安装（https://www.anaconda.com/download/），Anaconda最新版本基于python 3.7版本的，但目前Tensorflow还不提供python 3.7的安装包，因此在Tensorflow安装时还需额外的配置修改。Anaconda可以选择安装python 3.6版本的，Tensorflow直接可以下载安装。
2，安装Pycharm开发集成环境。（https://www.jetbrains.com/pycharm/）
3，安装Pytorch 1.0.0版本。

>>> import torch至此，Pytorch 1.0.0安装成功！
4，Tensorflow安装。
Anaconda安装的是python3.7的版本，Tensorflow支持python3.6以下的版本，并不直接支持python3.7，因此下载Tensorflow whl的版本以后需更改文件名进行安装。
