yolov8跟踪报错 File “_lapjv_src/_lapjv.pyx”, line 1, in init _lapjv ImportError: numpy.core.multiarray

我的代码

from ultralytics import YOLO

# Load an official or custom model
model = YOLO("weights/yolov8m.pt")  # Load an official Detect model
# Perform tracking with the model
results = model.track("./input/20240608-212555.mp4", show=True, tracker="bytetrack.yaml")  # with ByteTrack
