cv2 error, fly_seg

[DrinkAstragalus]

Hi, I met an error recently when the program calculated background image:
Traceback (most recent call last):
File "", line 198, in run_module_as_main
File "", line 88, in run_code
File "C:\Users\huang\micromamba\envs\mpy\Scripts\easyFlyTracker.exe_main.py", line 7, in

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
cv2.error: OpenCV(4.8.1) d:\a\opencv-python\opencv-python\opencv\modules\imgproc\src\color.simd_helpers.hpp:92: error: (-2:Unspecified error) in function '__cdecl cv::impl::anonymous-namespace'::CvtHelper<struct cv::impl::anonymous namespace'::Set<3,4,-1>,struct cv::impl::A0xd8611878::Set<1,-1,-1>,struct cv::impl::A0xd8611878::Set<0,2,5>,3>::CvtHelper(const class cv::_InputArray &,const class cv::_OutputArray &,int)'

Invalid number of channels in input image:
'VScn::contains(scn)'
where
'scn' is 1

It seems there is an error of color channels.

It should be
bg = sx[0]
in line 278 in fly_seg.py,
as 'keepdims' is set to false by default in stats.mode in SciPy v1.11.3.

Thank you for your feedback! This issue has been fixed, you can update easyFlyTracker and use it:
pip install --upgrade easyFlyTrakcer
Thanks.
