[jetson] PyQt5 설치하기

문제점 및 증상

pip3 명령을 이용하여 PyQt5를 설치하려고 하였더니, 다음과 같은 오류가 발생하였습니다.

nvidia@nvidia-OrinNX16G:~$ pip3 install pyqt5

NVIDIA Jetson Orin NX 환경에서 간단하게 PyQt5를 설치하는 방법을 알아보겠습니다.

해결 방안

최신 PyQt5를 설치하려고 하면, 미리 빌드된 패키지를 제공하고 있지 않아서 직접 소스를 다운로드 받아서 빌드를 하면, 위와 같은 오류가 발생하였습니다.

수동으로 직접 설치하는 방법은 "PySide2 (Qt for python) installation on Jetson Xavier - #5 by Muscle_Oliver":https://forums.developer.nvidia.com/t/160796/5 여기에 정리되어 있습니다. 이 방법으로 시도하려다가 굳이 최신버전인 5.15가 아니어도 된다는 생각에 다시 찾아보니, 손쉽게 설치할 수 있는 방법이 있었습니다.

다음과 같이 "sudo apt-get install python3-pyqt5" 명령을 수행하면 됩니다.

nvidia@nvidia-OrinNX16G:~$ sudo apt-get install python3-pyqt5

Do you want to continue? [Y/n] 

설치되는 패키지들이 꾀 많았습니다만, 설치 이후에 PyQt 프로젝트들이 정상적으로 실행되었습니다.
