Jetpack 3.3 OpenCV error No CUDA support (The library is compiled without CUDA support)

I’m attempting to build/run some code I inherited on a TX2 board with Jetpack 3.3. I get the following run-time message:

OpenCV error No CUDA support (The library is compiled without CUDA support)

I didn’t build OpenCV–simply installed via the Jetpack installer.

Do I need to rebuild OpenCV? Is there something else that could be wrong?

Not checked last JetPack version, but previously opencv3 package included in JetPack had no CUDA nor gstreamer support.

You can build and install your own version. You can look at these links:
https://github.com/AastaNV/JEP/blob/master/script/install_opencv3.4.0.sh
https://github.com/jetsonhacks/buildOpenCVTX2
https://jkjung-avt.github.io/opencv3-on-tx2/
https://github.com/econsystems/opencv

It sounds like I’m rebuilding OpenCV. Thanks for the links…
