Ubuntu Python: unable to pip install dlib - Failed building wheel for dlib and machine is almost stuck


I am trying to install dlib (machine learning library) for my django python environment. however, i cant get it installed. there is error and stuck.

based on this instruction, this is what I did https://www.pyimagesearch.com/2017/03/27/how-to-install-dlib/

$ sudo apt-get install build-essential cmake
$ sudo apt-get install libgtk-3-dev
$ sudo apt-get install libboost-all-dev

$ source somedotcomenv/bin/activate <-- virtualenv

$ pip install numpy
$ pip install scipy
$ pip install scikit-image
$ pip install dlib

however, it failed and i think stuck, its almost an hour at the last stage. Im not sure if its still compiling or not.

Solution

  • Try using the version of dlib in this pull request https://github.com/davisking/dlib/pull/1040. It removes the dependency on boost and should therefore fix your problem.
