hi everyone, anis again
i'm trying to run this object detection script:

Code:

import cv2from picamera2 import Picamera2from ultralytics import YOLO# Set up the camera with Picampicam2 = Picamera2()picam2.preview_configuration.main.size = (1280, 1280)picam2.preview_configuration.main.format = "RGB888"picam2.preview_configuration.align()picam2.configure("preview")picam2.start()# Load YOLOv8model = YOLO("yolov8n.pt")while True:    # Capture a frame from the camera    frame = picam2.capture_array()        # Run YOLO model on the captured frame and store the results    results = model(frame)        # Output the visual detection data, we will draw this on our camera preview window    annotated_frame = results[0].plot()        # Get inference time    inference_time = results[0].speed['inference']    fps = 1000 / inference_time  # Convert to milliseconds    text = f'FPS: {fps:.1f}'    # Define font and position    font = cv2.FONT_HERSHEY_SIMPLEX    text_size = cv2.getTextSize(text, font, 1, 2)[0]    text_x = annotated_frame.shape[1] - text_size[0] - 10  # 10 pixels from the right    text_y = text_size[1] + 10  # 10 pixels from the top    # Draw the text on the annotated frame    cv2.putText(annotated_frame, text, (text_x, text_y), font, 1, (255, 255, 255), 2, cv2.LINE_AA)    # Display the resulting frame    cv2.imshow("Camera", annotated_frame)    # Exit the program if q is pressed    if cv2.waitKey(1) == ord("q"):        break# Close all windowscv2.destroyAllWindows()
on my raspberry pi zero 2w. Crazy right, hhh
