Steps to Reproduce

when I use the blow commend:
sudo apt-get install python3.6-dev
and
sudo apt-get install python3-dev
it did not work,it still has the same errop

  • Version: dlib19.10
  • Platform: Ubuntu 16.04 64bit
  • Compiler:python 3.6.3 cmake version 3.5.2

I figured out why some people might be running into this issue.

tl;dr Recreate your virtualenv after you've installed the python3.6-dev package (or the python version your virtualenv is using).

Python 3.6 isn't supported in Ubuntu 16.04, so people may install it in different ways.

How I did it:

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt update
sudo apt install python3.6 python3.6-dev
sudo apt remove python3-dev # to ensure the system's Python 3.5 wouldn't interfere

mkvirtualenv test --python=/usr/bin/python3.6
# now in the "test" virtualenv
pip install dlib

This gives the same results as what other commenters got.

Tracing this, I tried to install from dlib source using python setup.py install and got the same error.

Going to the cmake build dir build/temp.linux-x86_64-3.6 I ran make VERBOSE=1 to show compiler command lines.

The first target to fail uses the command line:

[ 72%] Building CXX object CMakeFiles/dlib_python.dir/src/dlib.cpp.o
/usr/bin/c++  -DDLIB_VERSION=19.15.99 -Ddlib_python_EXPORTS -I/home/joel/src/dlib/dlib/external/pybind11/include -I/home/joel/.virtualenvs/test/include/python3.6m -I/home/joel/src/dlib/dlib/..  -O3 -DNDEBUG -fPIC -fvisibility=hidden   -std=c++14 -DDLIB_NO_ABORT_ON_2ND_FATAL_ERROR -DDLIB_JPEG_SUPPORT -DDLIB_USE_BLAS -DDLIB_USE_LAPACK -DDLIB_USE_CUDA -DDLIB_PNG_SUPPORT -DDLIB_GIF_SUPPORT -mavx -Wreturn-type -std=gnu++11 -o CMakeFiles/dlib_python.dir/src/dlib.cpp.o -c /home/joel/src/dlib/tools/python/src/dlib.cpp

The issue is with -I/home/joel/.virtualenvs/test/include/python3.6m - which doesn't exist. The headers are in /usr/include/python3.6m.

Solution: Create a new virtualenv after python3.6-dev (or equivalent) package is installed

Why? When you create a virtualenv the include directories will be installed in the virtualenv if they exist.

So if you create a virtualenv, but don't have the headers for python (e.g. from python3.6-dev), then even if you install the headers in a system location afterwards, they won't be in the virtualenv and dlib will failed to build because of this.

Hope this helps!

I also use Ubuntu 16.04 and this doesn't happen.

Post a complete set of instructions that causes this to happen. So you log in to the computer, and then what does someone type to make this happen? You obviously already did a lot of other stuff like setup a virtualenv. You can't post a question like "I did 20 commands I'm not going to tell you about and now python is broken, what did I do?". For all I know this has nothing to do with dlib.

Getting the same error here.

Environment

  • Platform: Ubuntu 16.04
  • Python Version: 3.6.6
  • Pip Version: 18.0 (In a virtualenv)
  • Cmake version: 3.12.0 CMake suite maintained and supported by Kitware (kitware.com/cmake).

Steps:

  • Navigate to project directory
  • Activate virtualenv
  • pip install dlib

Did you install the python dev package?

More importantly, what exactly do you type in a terminal? Provide complete instructions to replicate this error.

davisking picture davisking on 29 Jul 2018

Install the what now?

Reproduction Steps:

cd Desktop
mkdir example
cd example
virtualenv env -p python3.6
source env/bin/activate
pip install dlib

# Above error occurs
FelixVicis picture FelixVicis on 29 Jul 2018

On Ubuntu the package is called python3-dev.

davisking picture davisking on 29 Jul 2018

I can't find anything in the docs for dlib about the dev package. Why do I need it for dlib?

I figured out why some people might be running into this issue.

tl;dr Recreate your virtualenv after you've installed the python3.6-dev package (or the python version your virtualenv is using).

Python 3.6 isn't supported in Ubuntu 16.04, so people may install it in different ways.

How I did it:

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt update
sudo apt install python3.6 python3.6-dev
sudo apt remove python3-dev # to ensure the system's Python 3.5 wouldn't interfere

mkvirtualenv test --python=/usr/bin/python3.6
# now in the "test" virtualenv
pip install dlib

This gives the same results as what other commenters got.

Tracing this, I tried to install from dlib source using python setup.py install and got the same error.

Going to the cmake build dir build/temp.linux-x86_64-3.6 I ran make VERBOSE=1 to show compiler command lines.

The first target to fail uses the command line:

[ 72%] Building CXX object CMakeFiles/dlib_python.dir/src/dlib.cpp.o
/usr/bin/c++  -DDLIB_VERSION=19.15.99 -Ddlib_python_EXPORTS -I/home/joel/src/dlib/dlib/external/pybind11/include -I/home/joel/.virtualenvs/test/include/python3.6m -I/home/joel/src/dlib/dlib/..  -O3 -DNDEBUG -fPIC -fvisibility=hidden   -std=c++14 -DDLIB_NO_ABORT_ON_2ND_FATAL_ERROR -DDLIB_JPEG_SUPPORT -DDLIB_USE_BLAS -DDLIB_USE_LAPACK -DDLIB_USE_CUDA -DDLIB_PNG_SUPPORT -DDLIB_GIF_SUPPORT -mavx -Wreturn-type -std=gnu++11 -o CMakeFiles/dlib_python.dir/src/dlib.cpp.o -c /home/joel/src/dlib/tools/python/src/dlib.cpp

The issue is with -I/home/joel/.virtualenvs/test/include/python3.6m - which doesn't exist. The headers are in /usr/include/python3.6m.

Solution: Create a new virtualenv after python3.6-dev (or equivalent) package is installed

Why? When you create a virtualenv the include directories will be installed in the virtualenv if they exist.

So if you create a virtualenv, but don't have the headers for python (e.g. from python3.6-dev), then even if you install the headers in a system location afterwards, they won't be in the virtualenv and dlib will failed to build because of this.

Hope this helps!

Thanks everyone.I reinstall my Ubuntu system and the problem is solved.

I experienced the same issue while trying to install dlib with cuda enabled as instructed by Adrian @pyimagesearch.
I have Ubuntu 16.04.5 amd64 LTS server installed with python 3.5m as default.
I have CUDA 8.0 and CUDNN 6.0 installed.
I solved the problem by fixing the virtual environment as follows:

my virtual environment name is 'dl4cv'. I used the same name without doing anything.

$ deactivate
$ sudo apt-get update
$ sudo apt-get install python3 python3-dev
$ mkvirtualenv dl4cv -p python3

After the commands above, i have rerun "python setup.py line. The installation continued from %70, and finished succesfully.
I think mkvirtualenv fixes the linking of headers those could not be found in previous installation trial.
