我正在嘗試部署我的 ml model 來對植物圖像進行分類，但是即使路徑正確，我也找不到文件錯誤

Question

錯誤是cmd 錯誤截圖上圖顯示了我在 cmd 中面臨的錯誤

首先我通過 html 文件上傳一張圖片，這個上傳的文件被傳遞到我保存的 cnn model 將用於預測植物病害，這將顯示為 Z78E6221F6393D1356681DB398F14CE6681DB398F14CE6。

要么像這樣添加：

import os

basedir = os.path.abspath(os.path.dirname(__file__))
UPLOAD_FOLDER = os.path.join(basedir, '/uploads')

或者

UPLOAD_FOLDER = os.getcwd() + '/uploads'
