Research direction
Start with the repository README and its checklist, then compare the reported opencv-python 4.5.3 behavior with the OpenCV repository linked in the issue. The report names no file or test here; done would require determining whether the build toolchain or prebuilt package is responsible, or redirecting the defect to OpenCV itself.
Written by the indexing model from the issue text.
Description
Expected behaviour
opencv filter should return the filtered image with the same number of channel as input, i.e.
a = np.random.randint(255, size=(100,100,600)).astype(np.uint8)
cv2.blur(a, ksize=[3,3]).shape # should be (100,100,600)
Actual behaviour
error: OpenCV(4.5.3) /tmp/pip-req-build-xw6jtoah/opencv/modules/core/src/matrix.cpp:1102: error: (-215:Assertion failed) dims <= 2 && step[0] > 0 in function 'locateROI'
Steps to reproduce
- example code
- Ubuntu20.04
- x86
- opencv-python 4.5.3
