这里仅记载下labelImg的安装过程，因为有坑。
我的安装方式是从源码编译，环境ubuntu16.04，一开始是使用python2安装，从github上下载好源码，然后执行安装命令
sudo apt-get install pyqt4-dev-tools
sudo pip install lxml
make qt4py2
python labelImg.py
make qt4py2的时候，会显示如下
pyrcc4 -py2 -o resources.py resources.qrc Couldn't open /home/wzy/labelImg-master/icons/next.png Couldn't open /home/wzy/labelImg-master/icons/zoom-out.png Couldn't open /home/wzy/labelImg-master/icons/format_voc.png Couldn't open /home/wzy/labelImg-master/icons/expert2.png Couldn't open /home/wzy/labelImg-master/icons/copy.png Couldn't open /home/wzy/labelImg-master/icons/format_yolo.png Couldn't open /home/wzy/labelImg-master/icons/color_line.png Couldn't open /home/wzy/labelImg-master/icons/prev.png Couldn't open /home/wzy/labelImg-master/icons/cancel.png Couldn't open /home/wzy/labelImg-master/icons/edit.png Couldn't open /home/wzy/labelImg-master/icons/labels.png Couldn't open /home/wzy/labelImg-master/icons/color.png Couldn't open /home/wzy/labelImg-master/icons/close.png Couldn't open /home/wzy/labelImg-master/icons/quit.png Couldn't open /home/wzy/labelImg-master/icons/fit-window.png Couldn't open /home/wzy/labelImg-master/icons/fit-width.png Couldn't open /home/wzy/labelImg-master/icons/resetall.png Couldn't open /home/wzy/labelImg-master/icons/eye.png Couldn't open /home/wzy/labelImg-master/icons/undo.png Couldn't open /home/wzy/labelImg-master/icons/save-as.png Couldn't open /home/wzy/labelImg-master/icons/done.png Couldn't open /home/wzy/labelImg-master/icons/open.png Couldn't open /home/wzy/labelImg-master/icons/app.png Couldn't open /home/wzy/labelImg-master/icons/file.png Couldn't open /home/wzy/labelImg-master/icons/help.png Couldn't open /home/wzy/labelImg-master/icons/zoom.png Couldn't open /home/wzy/labelImg-master/icons/save.png Couldn't open /home/wzy/labelImg-master/icons/zoom-in.png Couldn't open /home/wzy/labelImg-master/icons/verify.png Couldn't open /home/wzy/labelImg-master/icons/objects.png
再然后执行labelImg.py会报错
Traceback (most recent call last):
File "labelImg.py", line 29, in <module>
import resources
File "/home/wzy/文档/labelImg-master/resources.py", line 9, in <module>
from PyQt4 import QtCore
ImportError: No module named PyQt4
找不到pyqt4，然额明明安装过。
于是改用python3，OK了，命令如下，与Python2很像。
sudo apt-get install pyqt5-dev-tools sudo pip3 install lxml make qt5py3 python3 labelImg.py
软件截图如下
