How to install dlib v19.9 or newer (w/ python bindings) from github on macOS and Ubuntu

Pre-reqs:

  • Have Python 3 installed. On macOS, this could be installed from homebrew or even via standard Python 3.6 downloaded installer from https://www.python.org/download. On Linux, just use your package manager.
  • On macOS:
    • Install XCode from the Mac App Store (or install the XCode command line utils).
    • Have homebrew installed
  • On Linux:
    • For a full list of apt packages required, check out the example Dockerfile and copy what's installed there.
    • These instructions assume you are using Ubuntu 16.04 or newer. If you are using 14.04, you can try these installation instructions instead to work around the old CMake version.
  • These instructions assume you don't have an nVidia GPU and don't have Cuda and cuDNN installed and don't want GPU acceleration (since none of the current Mac models support this).

Clone the code from github:

git clone https://github.com/davisking/dlib.git

Build the main dlib library (optional if you just want to use Python):

cd dlib
mkdir build; cd build; cmake ..; cmake --build .

Build and install the Python extensions:

cd ..
python3 setup.py install

At this point, you should be able to run python3 and type import dlib successfully.

if required login-pswd, then clone in this way:
git clone git@github.com:davisking/dlib.git

if you have a python version of 3.7.x then instead of
python3 setup.py install
do
python3.7 setup.py install

what should i do??

I just made that mistake because the command failed the first i tried, soi I installed cmake, than the second time I tried your error appeared to me due to me not being at folder /dlib, but /dlib/build

Hi, how do we cross compile python binding libs on new MAC M1 for x86_64 ? I tried following and still got arm64.

make
cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 ..
cmake --build .
python3 setup.py install

find . -name "*.so" -exec file {} ;
./build/lib.macosx-10.9-x86_64-3.9/_dlib_pybind11.cpython-39-darwin.so: Mach-O 64-bit bundle arm64

How can I build python bindings which are for x86_64 ?

Probably I have the same problem with new MAC M1. No matter what I do, I get the same error.

I am not familiar with pip, but this simple command work on ubuntu 20.04:

pip install dlib-binary

referenced from: https://pypi.org/project/dlib-binary/

then we can import dlib in python3:

Python 3.8.10 (default, Mar 15 2022, 12:22:08)
[GCC 9.4.0] on linux

I have same issue ,
but when I check on repository dlib.
I found some replay for mac m1.

Please uninstall your dlib . And do this Step.

  1. brew install cmake
  2. brew install dlib
  3. pip install dlib
