cv2 报错
error: OpenCV(4.6.0) /io/opencv/modules/imgproc/src/color.simd_helpers.hpp:94: error: (-2:Unspecified error) in function ‘cv::impl::{anonymous}::CvtHelper::CvtHelper(cv::InputArray, cv::OutputArray, int) [with VScn = cv::impl::{anonymous}::Set<3, 4>; VDcn = cv::impl::{anonymous}::Set<3, 4>; VDepth = cv::impl::{anonymous}::Set<0, 2, 5>; cv::impl::{anonymous}::SizePolicy sizePolicy = cv::impl::::NONE; cv::InputArray = const cv::_InputArray&; cv::OutputArray = const cv::_OutputArray&]’

Unsupported depth of input image:
‘VDepth::contains(depth)’
where
‘depth’ is 6 (CV_64F)

调整数据的类型即可， np.float32 或者 uint8

cv2.cvtColor(over.astype("uint8"), cv2.COLOR_RGB2BGR)
