使用python怎么實現(xiàn)一個人臉識別打卡系統(tǒng)？相信很多沒有經(jīng)驗的人對此束手無策，為此本文總結(jié)了問題出現(xiàn)的原因和解決方法，通過這篇文章希望你能解決這個問題。
1、云計算，典型應(yīng)用OpenStack。2、WEB前端開發(fā)，眾多大型網(wǎng)站均為Python開發(fā)。3.人工智能應(yīng)用，基于大數(shù)據(jù)分析和深度學(xué)習(xí)而發(fā)展出來的人工智能本質(zhì)上已經(jīng)無法離開python。4、系統(tǒng)運維工程項目，自動化運維的標配就是python+Django/flask。5、金融理財分析，量化交易，金融分析。6、大數(shù)據(jù)分析。
