1. 教程大纲 Workshop Content


Lesson 1: Basic usage of WeChat Python API

  • 使用和开发微信个人号聊天机器人:一种Python编程接口 (Use WeChat Python API)
  • 用微信App "扫一扫" QR码图片来自动登录 (Log-in WeChat account)
  • 查找指定联系人或群聊 (Scan contact list)
  • 发送信息(文字、图片、文件、音频、视频等) (Send message: text, image, file, voice, video, etc)
  • 接收信息 (Receive message, and keep 'listening')
  • 自动回复 (Receive message and then automaticaly reply)
  • 自定义复杂消息处理,例如:信息存档、回复群聊中被@的消息 (Advanced message processing and reply)


Lesson 2: Image Recognition & Processing

  • 识别图片消息中的物体名字 (Recognize objects in image) [1] 物体名 (General Object) [2] 地标名 (Landmark Object) [3] 商标名 (Logo Object)

  • 识别图片消息中的文字 (OCR: Extract text from image) 包含简单文本翻译 (Call text translation API)

  • 识别人脸 (Recognize human face) 基于人脸的表情来识别喜怒哀乐等情绪 (Identify sentiment and emotion from human face)

  • 不良内容识别 (Explicit Content Detection)


Lesson 3: Natural Language Processing 1

  • 消息文字转成语音 (Speech synthesis: text to voice)
  • 语音转换成消息文字 (Speech recognition: voice to text)
  • 消息文字的多语言互译 (Text based language translation)


Lesson 4: Natural Language Processing 2

  • 消息文字中名称实体的识别 (Name-Entity detection)
  • 消息文字中语句的情感分析 (Sentiment analysis, Sentence level)
  • 整篇消息文字的情感分析 (Sentiment analysis, Document level)
  • 语句的语法分析 (Syntax / Grammar analysis)


Lesson 5: Video Recognition & Processing

  • 识别视频的场景片段 (Detect shots change in video)
  • 识别视频消息中的物体名字 (Recognize objects in video/shots)
  • 直接搜索视频内容 (Search content in video)


Lesson 6: Intelligent & Interactive Chat-bot Applications

  • 多语言翻译器 (Language translator)
  • 图文多媒体的订阅和点播 (Multi-media broadcast & on-demand subscription)
  • 文章的概括和缩写 (Automatic article summary)
  • 不良图片的识别;不良视频片段的自动识别和定位 (Explicit content detector: i.e. adult content or violent content)
  • 基于商品图片的搜索和商家价格比较 (Best retail price finder using an image of goods)

2. 开发环境安装


Option 1: Use a Virtual Machine to run in your own computer (Difficulty level: Easy, like being a boss)

  • Download a pre-configurated Ubuntu Linux virtual machine (25 GB size), which contains all environment setup:
  • Start the VM using Virtualbox. Free Virtualbox download:
  • Click iss-env-py3 Jupyter icon on desktop to start Jupyter Notebook
  • Choose your favorite file folder, then git clone/pull workshopblog notebooks from Github:

On desktop, click 'Solution WeChat Software Robot' to start the quick demo in terminal, or manually start by command:

$ python workshopblog/wechattool/terminal-script-py/


Option 2: Use Cloud Platform (Difficulty level: Medium, as nudging your colleague)

Create an account in Google Cloud Platform (GCP) * Complete GCP Registration: <--- In case you are lost here, quick guide: * Go to GCP Console: * Create a new project:

project id: kudosdata01 [This is uniquie GCP project-id, which you MUST change to your own id.]

project name: kudosdata01 [You MAY change to your own name.]

zone: asia-east1-b [Choose a data center near your location.]

  • Enable GCP Compute Engine API for new project, using GCP API Manager

Start Datalab (Jupyter python notebook) using Cloud Shell * Create/Connect a GCP Compute Engine virtual machine to use Datalab: kudosdata01-vm-datalab-workshop <--- In case you are lost here, quick guide:

gcloud projects list

gcloud config set core/project kudosdata01 [your own unique project-id]

gcloud config set compute/zone asia-east1-b

datalab create kudosdata01-vm-datalab-workshop --zone asia-east1-b [1st time for creation]

datalab connect kudosdata01-vm-datalab-workshop [2nd time for connection]

datalab stop kudosdata01-vm-datalab-workshop [stop VM after use]
* Open Datalab in web browser, then create a new notebook from datalab folder, then run below two command in notebook cell:

!git clone

%load workshopblog/


Option 3: Use your own computer (Difficulty level: High, as what you normally do)

  • Install Anaconda3 (This software includes many useful tools: Python3, Jupyter Notebook, pip)
  • Install Git & Git Bash
  • Install WeChat API package for Anaconda / python

pip install -U html

pip install -U qrcode

pip install -U itchat

  • Download workshop python notebook code from Github:
  • Start Jupyter Notebook (Here I use Git Bash command line tool)
  • Open a web browser if it's not started automatically. Go to url: http://localhost/tree

3. 恭喜您!安装成功了!下一步进入具体课程和实战操作,请打开第一课的笔记本。 Congratulations! After completing one of the installation options, you are now ready to rock! Go to GCP Datalab folder: workshopblog/wechattool, open Notebook and follow...

The History of every major Galactic Civilization tends to pass through three distinct and recognizable phases, those of Survival, Inquiry and Sophistication, otherwise known as the How, Why, and Where phases. For instance, the first phase is characterized by the question 'How can we eat?' the second by the question 'Why do we eat?' and the third by the question 'Where shall we have lunch?'
