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.

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:

root@copbint:~# python3
Python 3.8.10 (default, Mar 15 2022, 12:22:08)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dlib
>>>

Thanks, it does work!

Does anyone has a solution to that?

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

Im still facing the same issue?
Do you have any other ideas ?
Thanks

I have noticed there have some problem with dlib version 19.24.99, there is no 19.24.99 for dlib(only 19.24.0). Is there any comment of this issue?
