I have ported some code that ran successful on the TX1 over to the TX2. I’m getting the following error when I try to access the GPU.
OpenCV Error: Gpu API call (invalid device symbol) in linearRow, file /hdd/buildbot/slave_jetson_tx_3/35-O4T-L4T-R24/opencv/modules/gpu/src/cuda/row_filter.h, line 552 terminate called after throwing an instance of 'cv::Exception' what(): /hdd/buildbot/slave_jetson_tx_3/35-O4T-L4T-R24/opencv/modules/gpu/src/cuda/row_filter.h:552: error: (-217) invalid device symbol in function linearRow
Most articles online say this error is related to OpenCV being built with the wrong architecture and the fix set CUDA_GENERATION=AUTO during the OpenCV build process. Unfortunately, I’m trying use OpenCV4Tegra 2.4.13 and you don’t build this from source.
ubuntu@tx2-u1604-b:~/GFBTracker_GPU/staExec$ pkg-config --modversion opencv 2.4.13
I cleaned and built my code from scratch after the port and the CPU version works fine. The exact function it breaks on is cv::gpu::cornerHarris.
Has anyone had a similar issue or have any ideas to try?
