Can't find GpuMAT() functions in v4.2.0-dev compiled with python & CUDA
I have "successfully" compiled OpenCV v4.2.0-dev with python bindings and CUDA support on my Windows 10 machine following the many directions available online. I say successfully because compilation didn't throw errors. However, when I try to run a cv2.cuda command, I get an error such as:
>>>q=cv2.cuda.resize(base,dsize=(100,100))
---------------------------------------------------------------------------
error Traceback (most recent call last) <ipython-input-10-f4bd798fbe4a> in <module>
----> 1 q=cv2.cuda.resize(base,dsize=(100,100))
error: OpenCV(4.2.0-dev) C:\Users\M43259\Documents\python\opencv\modules\core\src\matrix_wrap.cpp:359: error: (-213:The function/feature is not implemented) getGpuMat is available only for cuda::GpuMat and cuda::HostMem in function 'cv::_InputArray::getGpuMat'
It turns out there is no python call available that has anything with GpuMAT in it. For example:
>>>cv2.cuda_GpuMAT()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last) <ipython-input-11-c14055330a2d> in <module>
----> 1 cv2.cuda_GpuMAT()
AttributeError: module 'cv2' has no attribute 'cuda_GpuMAT'
I'm stumped. I can provide loads of files and details if anyone wants.
EDIT 1 -------
While I'm looking for relevant cmake outputs, here is the output from cv2.getBuildInformation()

please append the cmake output to your question
(it seems, it did not properly pick up cuda components)
I quit the cmake.exe and VS2017 programs yesterday so I don't have those outputs on a screen. Do you have thoughts of what files on disk might be helpful instead? I did edit the question to include the getBuildInformation if that is helpful to start with?
That's strange, from your build info CUDA was picked up. Your GpuMat error is consistent with not having built with CUDA however I would expect your resize error to resemble the below
How did you install the python binary (cv2.cp37-win_amd64.pyd)? Did you manually copy it into the site-packages directory? Are other functions from cv2 working? Do you also have opencv installed through conda? If you didn't build with
-DOPENCV_SKIP_PYTHON_LOADER=ON
it may be worth deleting the site-packages/cv2 directory and manually copying cv2.cp37-win_amd64.pyd directly into site-packages. I guessshows the path to the dll built with CUDA and not one which you built previously without?
Does this help? Unfortunately, don't use key.
