OPENVINO for Windows on IEI DRPC-240

  • 硬體: DRPC-240-TGL-U
  • OS: Windows 10
  • 底下文中的 C:\Users\B622 代表使用者文件夾, 實際上會因使用者名稱會有不同, 在 PowerShell 中, 可以此變數 $env:USERPROFILE 獲得

OpenVINO 2022.2

  • 簡介: OpenVINO是intel開發的高速高性能計算機視覺和深度學習推理應用開發套件, 2022 版本對 Intel 核顯有較好的支援, 可善用核顯作硬體推理裝置.
  • 安裝位置: 照官方建議, 以 python virtualenv 方式安裝, 所以實際位置是在 C:\Users\B622\openvino_env\Libs\site-packages\openvino
  • 啟動方式:
  • 開啟 PowerShell V7, 執行 .\openvino_env\Scripts\activate, 應該會看到命令提示符號如下變化

金錢與財富有什麼不同？金錢不等於財富，金錢只是我們用來衡量財富的工具。錢是一種社會信用，能夠用來借貸他人時間。假如我把自己的工作做得很好，為社會創造了價值，社會說：「太感謝你了。因為你過去做的工作，未來我們要回報你。這裡是一張小借據，就把它叫做『錢』吧。」財富才是你想要的東西，是在你睡覺時，還能替你賺錢的資產。財富是工廠、是機器人，能製造出產品；財富是晚上仍在運轉，並服務顧客的電腦程式；財富是銀行裡的錢，可以被投資到其他資產或其他事業；甚至房子也是一種財富，因為可以出租，但跟擁有公司的一部分比起來，這種使用土地的效率可能比較低。所以，我對財富的定義是在你睡覺時還能增值、替你賺錢的事業或資產。
