Problem

After running pip install dlib to install the dlib library, I found I couldn’t run ⬇️

dlib.image_window()

The script will throw this error:

AttributeError: module 'dlib' has no attribute 'image_window'

Solution

After several researching, I tried to solve it by:

• uninstall the dlib: If you are using pip to install it, you could directly run pip uninstall dlib

• Clone dlib git repo to local: git clone https://github.com/davisking/dlib

• Run dlib setup.py: python setup.py install

• Try to check setup log, if it shows any GUI error, fix the error first. I’m having ⬇️ error, then I tried to download the XQuartz.

 *****************************************************************************
 *** DLIB GUI SUPPORT DISABLED BECAUSE X11 DEVELOPMENT LIBRARIES NOT FOUND ***
 *** Make sure XQuartz is installed if you want GUI support.               ***
 *** You can download XQuartz from: https://www.xquartz.org/               ***
 *****************************************************************************

• uninstall the dlib from pip: pip uninstall dlib

• install the dlib again: pip install dlib

• Run dlib python test file: python python_examples/face_detector.py examples/faces/2007_007763.jpg

• If it shows the RuntimeError, it means we need to turn on XQuartz when running the script, XQuartz is just like an app, open it will be okay ~

RuntimeError: Failed to initialize X11 resources

All of error should disappear now. 🎉
