sudo apt-get install pyqt5-dev-tools
pip3 install lxml
git clone https://github.com/tzutalin/labelImg.git
cd labelImg

开始编译

make all

报错如下

pyrcc5 -o libs/resources.py resources.qrc

python3 -m unittest discover tests

....Remove setting pkl file $/home/ps/.labelImgSettings.pkl

...E..

======================================================================

ERROR: test_setInvaleLocaleToEnv_printErrorMsg (test_stringBundle.TestStringBundle)

----------------------------------------------------------------------

Traceback (most recent call last):

File "/home/ps/dev/yolo/label/labelImg/tests/test_stringBundle.py", line 18, in test_setInvaleLocaleToEnv_printErrorMsg

KeyError: 'LC_ALL'

----------------------------------------------------------------------

Ran 10 tests in 0.105s

FAILED (errors=1)

make: *** [Makefile:11: testpy3] Error 1

设置环境变量export LC_ALL=en_US.UTF-8

使用指令如下

python3 labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

直接python3 labelImg.py的话默认如下

默认的label列表是在data/predefined_classes.txt

python3 labelImg.py ../../dataset/test/images/ ../../dataset/test/classes.txt

然后最好把auto save勾上

常用的快捷键：

w 创建矩形框

d 切换到下一张图

a 切换到上一张图

del 删除选中的标注矩形框

标注第一个图片看下

看下保存的标注文件
