/tmp/build_opencv/opencv_contrib/ is not available in docker image

[kukirokuk]

I try to use cuda cv2.cuda_CascadeClassifier, my application based on your docker image here https://hub.docker.com/r/mdegans/tegra-opencv But I receive error

cv2.error: OpenCV(4.5.1) /tmp/build_opencv/opencv_contrib/modules/cudaobjdetect/src/cascadeclassifier.cpp:155: error: (-217:Gpu API call) NCV Assertion Failed: NcvStat=4, file=/tmp/build_opencv/opencv_contrib/modules/cudalegacy/src/cuda/NCVHaarObjectDetection.cu, line=2363 in function 'NCVDebugOutputHandler'

When I check /tmp/ directory inside this docker image, its empty. Cat it be the reason why app is failing?

[kukirokuk]

I have installed opencv via build_opencv.sh script but tests fails. What can be wrong?

It's related to #43

Test data is missing. I will address it in the next release so that the test functionality works.

Anything not strictly needed at runtime is deleted, including any build files. It's by design. When I fix #43 I will address this as well so tests can be run.

Nope. It's just saying "the error is here in the source" and if it's still around you can check the .cpp, but you can also check that file on GitHub.

Possibly the container does not have permission to access the GPU. What's your docker run command?

100 % of my test failed, is it ok or some of them should only fail?

I run my app in docker-compose and there I have runtime: nvidia

When I try to run ./deviceQuery previously copied to container from host dir /usr/local/cuda/samples/ result is: `./deviceQuery Starting...

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35 -> CUDA driver version is insufficient for CUDA runtime version Result = FAIL`

[kukirokuk]

Should there be cuda 10_2 instead 10_0 in path? https://github.com/mdegans/nano_build_opencv/blob/docker/build_opencv.sh#L49

Yup, that's a bug and could prevent buildling something like pycuda. Thanks for spotting that.

Ack. looks like I edited your comment instead of hitting quote reply. Sorry. Not much sleep last night.

I run my app in docker-compose and there I have runtime: nvidia

I haven't tried compose, but if the options are the same as with docker run it should work fine. Try the example launch like this and let me know if it works:

$ sudo docker run --user $(id -u):$(cut -d: -f3 < <(getent group video)) --runtime nvidia -it --rm mdegans/tegra-opencv:latest

--user should not be required. It's just a suggest you not run any containers as root. Root inside the container is the same as root outside the container. In this case the uid could be some user dedicated to storing files for this container if you are using volumes/bind mounts.

I have the same result as you. ` Device count: 1

The most interesting part is that cuda haarcascade smile detector is working but others like face or eyes detector doesn`t work:

cv2.error: OpenCV(4.5.1) /tmp/build_opencv/opencv_contrib/modules/cudaobjdetect/src/cascadeclassifier.cpp:155: error: (-217:Gpu API call) NCV Assertion Failed: cudaError_t=702, file=/tmp/build_opencv/opencv_contrib/modules/cudale gacy/src/cuda/NCVHaarObjectDetection.cu, line=1157 in function 'NCVDebugOutputHandler'

Looks like the error is in this line:

https://github.com/opencv/opencv_contrib/blob/master/modules/cudaobjdetect/src/cascadeclassifier.cpp#L155

I don't know much in C++ language, maybe you can tell me what's the problem?

@kukirokuk

cudaError_t 702 means it timed out. Have you tried the same version outside docker?

Yep, same error. Only smile classifier works properly.
