[BUG] The result of cvtColor RGB2YUV is not same with opencv

[hezeli123]

opencv code：

from pathlib import Path
import numpy as np
import cv2
import cvcuda
import logging
import torch
from PIL import Image

img = cv2.imread('./0.jpg', cv2.IMREAD_UNCHANGED)
pil_img = Image.fromarray(img.astype(np.uint8))
image1 = np.array(pil_img)
image2 = cv2.cvtColor(image1, cv2.COLOR_RGB2BGR).astype(np.float32)
cv_YUV = cv2.cvtColor(image2, cv2.COLOR_BGR2YUV)

cvcuda

image = torch.from_numpy(image1).to(torch.uint8).cuda()
frame_hwc = cvcuda.as_tensor(image .cuda(), "HWC")
cvcuda_YUV = cvcuda.cvtcolor(frame_hwc, cvcuda.ColorConversion.RGB2YUV)

Describe the bug
cv_YUV != cvcuda_YUV

Expected behavior
cv_YUV == cvcuda_YUV
