This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.
из Ultralytics import YOLO
model = YOLO('yolov8n.pt')
results =
model.train(data="D:\Programming\Pythoncode\Computer_Vision\data.yaml",
epochs=1, imgsz=640)
И в data.yaml есть это:
train: D:\Programming\Pythoncode\Computer_Vision\train\images val:
D:\Programming\Pythoncode\Computer_Vision\valid\images test:
D:\Programming\Pythoncode\Computer_Vision\test\images
nc: 1
