mac sierra run program crash about labelimg HOT 7 CLOSED

I had already resolved this error.

it caused by qt bug. https://bugreports.qt.io/browse/QTBUG-58344

Now, I installed pyqt5.7, it works fine.

1. change current directory to brew repo:

cd "$(brew --repo)"

2. change to homebrew-core's formula dir:

cd Library/Taps/homebrew/homebrew-core/Formula/

3. reset and checkout pyqt5.rb file to pyqt 5.7 version (latest version is pyqt 5.8, it has bug.)

git reset 233b493d3b7fe4fe7e2882765507693517f9817a pyqt5.rb
git checkout pyqt5.rb

4. install pyqt5.7

brew install pyqt5.rb

5. reset and checkout to latest version (pyqt 5.8)

git reset HEAD pyqt5.rb
git checkout pyqt5.rb

Error on step 4. Pls help!

I think it would be worthy to add some more input here as this is the solution to a popular question.

If you installed [email protected] and still get the old error, you probably have [email protected]. Do brew uninstall pyqt to make sure you only have [email protected] in your system.

I have not installed [email protected] before

@dqhieu Did you already installed pyqt5?

@aaronshan I am not very familiar with brew structure but as you can see in my comment, it seems recently when you install pyqt5, there won't be any pyqt5.rb but only pyqt.rb. And that pyqt is version 5.8.2. Did pyqt5 change the way it's installed?

installing Qt5 through pip3 inside virtual environment worked just fine for me
This link was useful How can I install PyQt5 on Mac?

First Error I got

Traceback (most recent call last): File "labelImg.py", line 24, in <module> from PyQt4.QtGui import *

I uninstalled Qt5 using brew uninstall pyqt

I just use pip3 install PyQt5

Then ran
make qt5py3
python labelImg.py

Then got error
from lxml import etree ModuleNotFoundError: No module named 'lxml'

So installed pip3 install lxml

It worked Awesome!!!!!!!
