based on folloing site : prediction based on yolo

i have implemented following code :

from ultralytics import YOLO

# Build a YOLOv6n model from scratch
model = YOLO("yolov10n.pt")
results = model("human.png")

# Display the results
print(results[0].show())

where human.png is image like this :

but it generates such error :

AttributeError: Can't get attribute 'SCDown' on <module 'ultralytics.nn.modules.block' from 'C:\Users\User\PycharmProjects\Artificial_Inteligence\.venv\Lib\site-packages\ultralytics\nn\modules\block.py'>

i have uninstalled and installed again ultralytics,but still getting same error, please advice me what to do ?
