Build OpenCV 3.4 on NVIDIA Jetson AGX Xavier Developer Kit

原先內建的 OpenCV 放在 /usr

心建立的會放在 /usr/local

$ git clone https://github.com/jetsonhacks/buildOpenCVXavier.git
$ cd buildOpenCVXavier
$ git checkout v1.0
$ ./buildOpenCV.sh

sudo ln -s /usr/local/lib/python3.6/dist-packages/cv2.cpython-36m-aarch64-linux-gnu.so envs/OpenAiGym/lib/python3.6/site-packages/
