win10 測試YOLOV4 報錯Couldnt open file: yolov4.weights，Couldnt open file: yolov4.cfg（已解決）

---

錯誤描述

---

在玩YoloV4時，之前的錯誤都已經解決後，準備測試時

測試dog圖片

darknet.exe detector test cfg/coco.data yolov4.cfg yolov4.weights -ext_output dog.jpg

報錯Couldn’t open file: yolov4.cfg

測試視頻時

darknet.exe detector demo cfg/coco.data cfg/yolov4.cfg yolov4.weights 1.avi -out_filename res.avi

報錯Couldn’t open file: yolov4.weights

---

錯誤原因

---

測試代碼中的cfg/coco.data cfg/yolov4.cfg yolov4.weights 未指明具體路徑

---

解決方案

---

將cfg/coco.data cfg/yolov4.cfg yolov4.weights中所有文件夾指明具體路徑

darknet.exe detector test 
C:\Users\Wang\Downloads\darknet-master\build\darknet\x64\cfg\coco.data 
C:\Users\Wang\Downloads\darknet-master\build\darknet\x64\cfg\yolov4.cfg 
C:\Users\Wang\Downloads\darknet-master\build\darknet\yolov4.weights 
-ext_output dog.jpg

在命令行中測試dog圖片時這樣輸入

darknet.exe detector test C:\Users\Wang\Downloads\darknet-master\build\darknet\x64\cfg\coco.data C:\Users\Wang\Downloads\darknet-master\build\darknet\x64\cfg\yolov4.cfg C:\Users\Wang\Downloads\darknet-master\build\darknet\yolov4.weights -ext_output dog.jpg

darknet.exe detector demo C:\Users\Wang\Downloads\darknet-master\build\darknet\x64\cfg\coco.data C:\Users\Wang\Downloads\darknet-master\build\darknet\x64\cfg\yolov4.cfg C:\Users\Wang\Downloads\darknet-master\build\darknet\yolov4.weights 1.avi -out_filename res.avi

注意 路徑需要按照自己的來

調用攝像頭識別也行
