English slides ? 層級 Level：中階 Intermediate ? 分類 Category：教育 Education ? 摘要 Abstract ? 內容主要將透過PAIA機器學習系統，了解學生如何透過該系統學習AI與python，並依據 PAIA 系統的特性，揭露我們如何使用 Kubernetes API 配合 Python，重新架構與設計該系統拆分為各項微服務，來達到方便 PAIA 系統部署、維運、與快速更新的目標。此過程主要闡述解決四大問題： 1. Python 與 Kubernetes 配合使用，建立以 Infrastructure as code 的系統架構。 2. 微服務化後的系統可更新單一服務，不影響其他元件運作。 3. 透過 k8s configmap 參數化系統設定，方便快速多 (prod, stage, dev) 環境部署。 4. AI 模擬、訓練、與競賽的過程，都containerize化，並透過 k8s 特性集中 logs，易於查找問題與隔離問題。 ? 說明 Description ? 我們 PAIA 系統使用的是 Python Django框架，主要處理 API 的創建，包含 authentication, authorization，accounting 並連接 postgreSQL 資料庫。在我們 PAIA 的客戶端使用場景為，提供使用者一個透過 AI 學習撰寫程式碼，來與其他AI程式碼競賽的執行遊戲環境。使用者可以選擇除了Python 以外，還有 block-based 的 blockly (類似 scrach) 圖形化語言方式來撰寫 AI 程式碼，並在完成 AI model 的選用與 data training 之後上傳至我們的 PAIA 系統，進行以下執行3階段步驟的過程： Frontend (Vue/NuxtJS) ==== Backend (Django) ==== MLGame (Python/Pygame) 除了 frontend 部份不是使用 Python 以外，剩下兩個部份 backend 與 MLGame 皆使用 Python 與其相關技術。將會在此次演講闡述以下項目的實作與架構過程： 1. Backend: API design, serializer and its folder structure in Django, database creation and migration, redis and cache mechanism, pika and websocket, and AAA (authentication, authorization, accounting) design. 2. MLGame: rabbitmq consumer(pika) with websocket, kubernetes client API in python, python multiple inheritance and design pattern in AI fields 主要大綱為： ‧ What is PAIA? ‧ Why we build up AI learning system? ‧ Why Python? ‧ How we use python to design the architecture and its rich library to build up microservices ‧ How we do devops and maintenance on production ‧ How we apply the PAIA system into physical education environment ‧ What is the next approach of AI system PAIA ‧ Conclusion 可參考以下額外資料： - PAIA 系統網站：https://www.paia-arena.com/ - PAIA 系統介紹影片：https://youtu.be/N68eL2ZDeNc - 使用技術分享：https://bit.ly/3IMiyx1 ? 講者介紹 About Speaker - 邱文淇 (Ivan Chiou) ? 曾經在各大公司先後擔任過介面工程師、系統工程師、系統分析師、專案經理、產品經理、Scrum Master、前端主管等歷練，目前為 PAIA 團隊資深技術經理。專注於程式教育、遠端協同、敏捷思維、團隊領導與網站技術的研究、創新、與導入。對於多媒體融合、跨領域職能協同合作有相當豐富的經驗，自許為團隊的心靈導師 (Mentor)，為年輕的工程師注入希望並指引方向。 #pycontw #pyconapac2022 #python #paia #django #mlgame #pygame #pika Follow “PyCon Taiwan” ⭐️ Official Website: https://tw.pycon.org ⭐️ Facebook: https://www.facebook.com/pycontw ⭐️ Instagram: https://www.instagram.com/pycontw ⭐️ Twitter: https://twitter.com/PyConTW ⭐️ LinkedIn: https://www.linkedin.com/company/pycontw ⭐️ Blogger: https://pycontw.blogspot.com ... https://www.youtube.com/watch?v=lNBDTDyyJ8E

By using Streamlit and streamlit-webrtc, we can create web-based real-time computer vision apps only with ~10 or 20 additional lines of Python code. It's a new easy way to turn computer vision models into web-based demos and has some advantages over the conventional ways which use OpenCV. In this talk, I will demonstrate the development process using these libraries and show a variety of examples so that we see how easy and useful they are and can make use of them in daily development and research. ? 說明 Description ? Streamlit is a fast-growing framework with which developers can build web-based data apps only with Python code. streamlit-webrtc is a custom component for Streamlit which allows to use real-time video/audio streams on Streamlit apps. With a combination of these libraries, we can create web-based real-time video apps quickly. The speaker is the author of streamlit-webrtc, and has been selected as a member of the Streamlit Creators program for the contributions including it. A lightning talk about these technologies at PyCon JP 2021 is available: https://youtu.be/_LuLs8H1gJc About development using these libraries, following articles have been published: - Developing Web-Based Real-Time Video/Audio Processing Apps Quickly with Streamlit - Real-Time Video Streams With Streamlit-WebRTC As linked from the streamlit-webrtc repo, demo apps I have developed are available online: - Demo showcase including real-time object detection: https://share.streamlit.io/whitphx/streamlit-webrtc-example/main/app.py - Source code: https://github.com/whitphx/streamlit-webrtc-example/blob/main/app.py - Real-time Speech-to-Text: https://share.streamlit.io/whitphx/streamlit-stt-app/main/app_deepspeech.py - Source code: https://github.com/whitphx/streamlit-stt-app - Real-time style transfer: https://share.streamlit.io/whitphx/style-transfer-web-app/main/app.py - Source code: https://share.streamlit.io/whitphx/style-transfer-web-app/main/app.py - Real-time Tokyo 2020 Pictogram: https://share.streamlit.io/whitphx/tokyo2020-pictogram-using-mediapipe/streamlit-app - Source code: https://github.com/whitphx/Tokyo2020-Pictogram-using-MediaPipe - Video chat: online demo is not available because it does not have an auth mechanism and is only for private use. - Source code: https://github.com/whitphx/streamlit-video-chat-example ? 關於講者 About Speaker - Yuichiro Tachibana ?
