Labelimg: Installation in macOS Sierra:*** No rule to make target `qt4py2'. Stop.

[zhihongzeng2002]

laptop: MacBook Pro 2015, MacOS Sierra.

Installation:
brew install qt: success
brew install qt4: Error No formulae found in taps
brew install cartr/qt4: success
brew install libxml2: success
brew install pyqt: success
$ make qt4py2
make: * No rule to make target `qt4py2'. Stop.
$ python labelImg.py
python: can't open file 'labelImg.py': [Errno 2] No such file or directory

The current version:
qt 5.9.2 is already installed
libxml2 2.9.6 is already installed
pyqt 5.9_1 is already installed

Is there something missing?

[zhihongzeng2002]

I fixed this issue with the following solution:

1) git clone https://github.com/tzutalin/labelImg.git, and cd labelImg
2) brew install qt
3) brew install cartr/qt4
4) export PYTHONPATH=/usr/local/Cellar/libxml2/2.9.6/lib/python2.7/site-packages:/usr/local/Cellar/sip/4.19.3_4/lib/python2.7/site-packages/:/usr/local/Cellar/pyqt@4/4.12_1/lib/python2.7/site-packages:$PYTHONPATH
5) brew install libxml2
6) sudo easy_install pip
7) sudo pip install lxml (I install it because step 9 show "no module lxml")
8) make qt4py2
9) python labelImg.py

It works very well now.

[MatinC]

doesn't work for me, in high sierra

[zhihongzeng2002]

@MatinC
Could you post the error messages so that we can figure out what is missing?
For qt4 installation, there are several components. You may try:
brew install cartr/qt4/qt@4
brew install cartr/qt4/qt-legacy-formula
brew install cartr/qt4/pyqt@4

Could you please help me with it

[zhihongzeng2002]

@megha-17 I think that you may create a new issue. Your problem is different from the current issue.

[megha-17]

@zhihongzeng2002 , Actually I am also trying to install labelImg on my mac osx and have followed solution provided by you to install but it is not working and facing following issue:-

$ python labelImg.py
Traceback (most recent call last):

@megha-17
Here is my work env. You may check your work env or use python virtualenv (I tested) to repeat my work env. Good luck.
laptop: MacBook Pro 2015, MacOS high Sierra version 10.13.1 which was updated yesterday (I don't think it would matter)
python 2.7.10.

$brew install cartr/qt4/qt@4
qt@4 4.8.7_2 is already installed
$brew install cartr/qt4/qt-legacy-formula
cartr/qt4/qt-legacy-formula 999.0.0 is already installed
$brew install cartr/qt4/pyqt@4
pyqt@4 4.12_1 is already installed
$pip install lxml
Requirement already satisfied: lxml in /Library/Python/2.7/site-packages
$brew install libxml2
libxml2 2.9.6 is already installed

$git clone https://github.com/tzutalin/labelImg.git
$cd labelImg
$make qt4py2
pyrcc4 -py2 -o resources.py resources.qrc
$python labelImg.py

It works fine.

[RodolfoFerro]

Hey, this worked for me:

Python 3 + Qt5 (Works on macOS High Sierra)

brew install qt  # will install qt-5.x.x
brew install libxml2
make qt5py3
python labelImg.py
python  labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

[aysark]

Doesn't work for me on latest macOS.

make qt4py2

pyrcc4 -py2 -o resources.py resources.qrc

python labelImg.py

Segmentation fault: 11

[RodolfoFerro]

A possible thing happening is that you're not using Qt-5 with Python 3 or Qt-4 with Python 2.
What Python version are you using? Can you share your output from qmake --version? @aysark

[aysark]

Frankly i just gave up since it was taking way too long to bootstrap it, i downloaded this packaged version of labelmg:
https://github.com/jiyeqian/labelImg/releases/download/1.4.4-pre/labelImg_qt5py3_mac_latest.zip

[RodolfoFerro]

A better solution! 😃 👍

[ttungl]

Hope this https://github.com/tzutalin/labelImg/issues/202 will help, it works for my case.

[saikanam]

@aysark
You, sir, just made my day. Thanks

[pallavtrivedi03]

@aysark You saved my day. Thanks a ton.

[vijaysan]

@aysark Most elegant solution, ever ;-)

[wxianfeng]

when compile, i meet this:

➜  labelImg git:(master) make qt5py3
pyrcc5 -o resources.py resources.qrc
make: pyrcc5: No such file or directory

@aysark thx, Man ~

this app is very Cool ~ it dont need compile .

[vdalv]

This issue appears to be resolved. @wxianfeng Please open a separate issue if necessary.

Thanks,

I used a combo (High Sierra)
already had python 3.x and python 2.x

1.- git clone https://github.com/tzutalin/labelImg.git
2.- cd labelImg
3.- brew install qt
4.- brew install cartr/qt4/qt@4
5.- brew install libxml2
6.- make qt5py3
7.- python3 labelImg.py (used python3 !!)
8.- I used the application file explorer to choose the folder

[bubjanes]

@aysark has got the goods!

[svengateswaran]

pip3 install pyqt5 lxml

The above command seems to fix the following error:
make: pyrcc5: No such file or directory

Reference : https://pypi.org/project/labelImg/

[enyangxxx]

same issue with pyrcc5: No such file or directory

[tzutalin]

missing pyrcc is because pyqt5 is not installed properly.

If you are using mac, try $ pip install pyqt5 lxml. Or else you can check out how I set up for build machine

https://github.com/tzutalin/labelImg/blob/master/.travis.yml#L78

[javadba]

pyqt5 is in place but pyrcc5 is missing anyways. Any thoughts?

[sweihub]

Summary

MacOS: QT5 + Python3

pip3 install pyqt5 lxml
make qt5py3
python3 labelImg.py

Build an App:
python3 setup.py py2app -A sudo mv dist/labelImg.app /Applications/

[javadba]

As I mentioned "pyqt5 is in place".

$ python3 -c "from PyQt5.QtCore import *; import lxml"
$

$make qt5py3
pyrcc5 -o libs/resources.py resources.qrc
make: pyrcc5: No such file or directory
make: *** [qt5py3] Error 1
