套件名稱叫 python-dotenv，但 import 時寫的是 dotenv。>　pip install python-dotenv這樣做的好處是不用把 API Key 直接寫在程式裡，例如避免：

如何使用 WSL 在 Windows 上安裝 Linux> wsl --install> wsl --list --verbose
Windows 子系統 Linux 版 沒有已安裝的發佈。這表示 WSL 已啟用，但目前沒有安裝任何 Linux 發佈版，例如 Ubuntu、Debian 等。你會看到可安裝的發佈版清單。最常用的是 Ubuntu，可以直接安裝：> wsl --install -d Ubuntu

它們只分擔「CPU 端的資料前處理」，完全不分擔「GPU 端的模型運算」。 forward / backward / 梯度更新永遠是主行程一個人在 GPU 上做，4 個 worker 做的是讀圖、做資料增強、把標註轉成 tensor 這些跟模型本身無關、但訓練前必須做的雜活。
為什麼要開「行程」而不是「執行緒」
讀圖、resize、mosaic/隨機增強這些工作是 CPU + 硬碟 I/O bound。如果用 Python 的 threading 來做，會被 GIL（全域解釋器鎖）卡住——同一時間還是只有一個執行緒在真正執行 Python bytecode，多執行緒在這種 CPU 密集工作上幾乎沒有平行效益。PyTorch 的 DataLoader 因此選擇用 multiprocessing：每個 worker 是一個完全獨立的作業系統行程，各自有自己的 Python 解釋器、自己的 GIL，才能真正利用到多核心 CPU 同時處理。

Load Port
在半導體製造流程中，Load Port 安裝在設備前端（EFEM）外，
作為晶圓載體（如 FOUP 或 FOSB）進出設備的接口，確保晶圓的潔淨度和安全。
