- Windows & Linux
- OS X. Binaries for OS X are not yet available. Help would be appreciated. At present, it must be built from source.
Linux/Ubuntu/Mac requires at least Python 2.6 and has been tested with PyQt 4.8.
sudo apt-get install pyqt4-dev-tools sudo pip install lxml make all ./roLabelImg.py ./roLabelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]
brew install qt qt4 brew install libxml2 make all ./roLabelImg.py ./roLabelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]
Download and setup Python 2.6 or later, PyQt4 and install lxml.
Open cmd and go to roLabelImg directory
pyrcc4 -o resources.py resources.qrc python roLabelImg.py python roLabelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]
docker pull tzutalin/py2qt4 docker run -it \ --user $(id -u) \ -e DISPLAY=unix$DISPLAY \ --workdir=$(pwd) \ --volume="/home/$USER:/home/$USER" \ --volume="/etc/group:/etc/group:ro" \ --volume="/etc/passwd:/etc/passwd:ro" \ --volume="/etc/shadow:/etc/shadow:ro" \ --volume="/etc/sudoers.d:/etc/sudoers.d:ro" \ -v /tmp/.X11-unix:/tmp/.X11-unix \ tzutalin/py2qt4
