Error when trying to make OpenKAI on Jetson TX2

[aman-patel]

Hi,

I'm trying to run openKAI on the Nvidia Jetson TX2 flashed with the jetpack 3.3.1. I have installed OpenCV 3.4.0 on the TX2.

I'm getting the following error when I run the make command :

/home/nvidia/OpenKAI/src/Detector/_DNNdetect.cpp: In constructor ‘kai::_DNNdetect::_DNNdetect()’:
/home/nvidia/OpenKAI/src/Detector/_DNNdetect.cpp:22:15: error: ‘DNN_BACKEND_OPENCV’ is not a member of ‘cv::dnn’
m_iBackend = cv::dnn::DNN_BACKEND_OPENCV;

I am following the steps of the documentation : http://docs.openkai.xyz/tegrabuild.html#jetson-inference-batch.

Any help regarding the issue would be great.
Thanks you!

Hi, I think you need to upgrade to OpenCV > 4.0 to solve the issue, here is a reference:

OpenKAI/sh/Setup/OpenKAI_dev_setup.sh

Line 138 in 037250c

Hi,
I follow OpenKAI/sh/Setup/OpenKAI_dev_setup.sh to make OpenKai on Tx2, bit I got some errors and I don't know where is wrong
My jetpack version is 4.4

I would appreciate it if someone can help
Thanks you!
