前期考虑使用了图灵机器人，有两种实现方式绑定公众号和加入群聊。图灵机器人可以直接绑定公众号，使用过程还是不错的，不用明确@，可以直接进行对话，上下文逻辑比微软小冰要好，有1000条/天的限制。第二种方案则是使用第三方插件，绑定微信号，用机器人运行微信号，缺点就是需要一直运行微信不能退出，逻辑不明显。好吧，逻辑都不是很明显。
接下来考虑了Sam Gu调用itchat的方式[1]。Sam 使用谷歌云平台集成ItChat微信聊天机器人并集成深度人工智能应用，首先安装Jupyter Notebook。
登陆服务器，可以通过控制台，或者putty, mobaxterm等工具，前者简洁后者提供文件操作界面。
mkdir anaconda #创建安装目录
cd anaconda #将进入安装目录
wget https://repo.continuum.io/archive/Anaconda3-5.0.1-Linux-x86_64.sh #下载安装包
bash Anaconda3-5.0.1-Linux-x86_64.sh #安装另外卸载用rm -rf anaconda3
jupyter notebook --generate-config --allow-root ipython from notebook.auth import passwd passwd() #设置密码会生成hashed password，复制
vi ~/.jupyter/jupyter_notebook_config.py 复制粘贴以下几行，然后运行。具体操作可以参翼起小飞在社区的博文，即[2]。
c.NotebookApp.ip='*'c.NotebookApp.password = u'把上面的文本粘贴到这里'
c.NotebookApp.open_browser = Falsec.NotebookApp.port =8888nohup jupyter notebook --allow-root
然后运行Jupyter Notebook，并在浏览器登录。Sam是在谷歌云台（第一年免费，赠送300美元，当然阿里云也有学生优惠）上创建的，基本原理是一致的，他的视频里讲的也是非常清楚，这里把这些内容搬运过来。登陆Jupyter Notebook后，创建一个文件夹存放相关文件，然后创建Python3文件，在其命令行里复制并运行以下命令，第二条运行两次。
!git clone https://github.com/telescopeuser/workshop_blog.git%load workshop_blog/setup_cloud.py
运行lesson 1就可以开始了。当然这些命令也可以在服务器直接调用，Jupyter Notebook在这里更多的是交互界面的作用。接下来的图形识别要调用机器学习，Sam使用了Google Cloud Platform's Machine Learning APIs，直接调用就可以，复制粘贴API，然后再运行lesson 2。Lesson3 主要讲了语音的识别，翻译。Lesson4就高深一点，涉及到情感语义分析，接下来的lesson5涉及到从视频中提取信息。按照参考文献[1]的知识进行操作即可。但是，这样调用谷歌API，和之前挂用图灵机器人，最大的区别就是多了几行代码，Well，很多行代码，和我预想的还是有差距的。
然后在warmheartli的项目里面发现了些有趣的内容，不过我要准备去挤火车了……
更新于2018年9月17日星期一：收集聊天语料
莫名其妙的更新被删除掉，好在以前的都还留着，从新再发语料的收集不再考虑使用字幕，从微博爬取数据，作为日后的语料和机器学习用，爬虫的方法参考nghuyong，nghuyong的方法在验证登录的时候存在无法识别。因此滑块验证的方法参考LiuXingMing/WeiboSliderCode；Python3WebSpider/CrackWeiboSlide；bone_ace/article/details/71056741，当然他们的方法也并不是有效，尝试了很多方法后，最简单粗暴地是把验证图形的矩阵直接放在cookies.py里面。
