Python dlib not working properly on Apple Silicon chip (M4)

I want to use dlib on Python. I installed it without any issue. The problem is that, when I try to import it, I get this error:

Traceback (most recent call last):
  File "/Users/elgamernovato/Projects/Free Code/Python/Test Proyecto Rene/test.py", line 1, in <module>
    import dlib
  File "/Users/elgamernovato/Projects/Free Code/Python/Test Proyecto Rene/venv/lib/python3.13/site-packages/dlib/__init__.py", line 19, in <module>
    from _dlib_pybind11 import *
ImportError: 
dlopen(/Users/elgamernovato/Projects/Free Code/Python/Test Proyecto Rene/venv/lib/python3.13/site-packages/_dlib_pybind11.cpython-313-darwin.so, 0x0002): 
tried:

'/System/Volumes/Preboot/Cryptexes/OS/Users/elgamernovato/Projects/Free Code/Python/Test Proyecto Rene/venv/lib/python3.13/site-packages/_dlib_pybind11.cpython-313-darwin.so' (no such file),

I installed cmake, boost and openblas using brew. I installed dlib again for arm:

CMAKE_PREFIX_PATH=$(brew --prefix) arch -arm64 pip install dlib --no-binary dlib

But still the same error.

I even ensured python is working for arm64 with

arch -arm64 python3 -c "import platform; print(platform.machine())"

On the terminal I ran uname -m to confirm that I am using arm64.

I expected dlib to import smoothly, but simply importing it causes errors.

Yeah guys, I found the solution in this video: https://www.youtube.com/watch?v=F0V5AbxwzSE

First, I ran pip3 install cmake, then pip3 install dlib==29.24.2, now everything it's working fine.

Try installing it first through Homebrew. Run this to install it through Homebrew (make sure you have Homebrew downloaded) and it will install dlib (and dependencies):

python3 -m venv env
brew install cmake
brew install boost
brew install boost-python
brew install dlib
source env/bin/activate
python3 -m pip install numpy
python3 -m pip install scipy
python3 -m pip install scikit-image
python3 -m pip install dlib
