Could't open YOLOv3 custom trained file

[amar-mustaqim]

I've done training YOLO v3 of my own dataset(9000 images of 3 different classes). But when i try to run the detection, this error appeared. Any suggestion?

@amar-mustaqim What command did you enter ?

It looks like the weights' path is wrong.

[amar-mustaqim]

darknet.exe detector test data/obj.data yolo-obj.cfg yolo-obj_last.weights. I stop the training after 6000 iterations.

U need an image path after that darknet.exe detector test data/obj.data yolo-obj.cfg yolo-obj_last.weights image.jpg

check yolo-obj_last.weights path try with yolo-obj_6000.weights path

[amar-mustaqim]

Actually both yolo-obj_last.weights and yolo-obj_6000.weights are at the same path which is in x64/backup. I understand about the image path, but what if I want to run the detection through the webcam?

[ghost]

darknet.exe detector demo data/obj.data yolo-obj.cfg x64/backup/yolo-obj_last.weights 0

for webcam it's demo command and you need opencv compiled You have to enter the exact path for .data .cfg .weights files 0 is for webcam

Thank you so much for your help mate! Will figure it out 😄

I try to run this command:

darknet.exe detector demo data/obj.data yolo-obj.cfg backup/yolo-obj_last.weights 0

and this error appear.

[vaishnavm217]

darknet.exe detector demo data/obj.data yolo-obj.cfg backup/yolo-obj_last.weights 0

Correct command is darknet.exe detector demo data/obj.data yolo-obj.cfg backup/yolo-obj_last.weights -c 0

General structure of commands are darknet.exe <function1> <function2> <data path> <cfg path> <weights path> <rest of things (image, camera,-show etc)>

Thank you so much! It works!
