cv2.error: OpenCV(4.9.0) 👎 error: (-5:Bad argument) in function 'cvtColor'

I encountered the following issues during execution：

Traceback (most recent call last):
File "/Halo/hallo/scripts/inference.py", line 376, in
inference_process(command_line_args)
File "/Halo/hallo/scripts/inference.py", line 163, in inference_process
source_image_lip_mask = image_processor.preprocess(
File "/root/anaconda3/envs/hallo/lib/python3.10/site-packages/hallo/datasets/image_processor.py", line 124, in preprocess
faces = self.face_analysis.get(cv2.cvtColor(np.array(ref_image_pil.copy()), cv2.COLOR_RGB2BGR))
cv2.error: OpenCV(4.9.0) 👎 error: (-5:Bad argument) in function 'cvtColor'

Overload resolution failed:

• src is not a numpy array, neither a scalar
• Expected Ptrcv::UMat for argument 'src'

appreciate for explaination

Could you check whether ref_image_pil.copy() is empty?
