This file basically just uses CMake to compile the dlib python bindings project
|
|
located in the tools/python folder and then puts the outputs into standard
|
|
python packages.
|
|
|
|
To build the dlib:
|
|
python setup.py build
|
|
To build and install:
|
|
python setup.py install
|
|
To package the wheel (after pip installing twine and wheel):
|
|
python setup.py bdist_wheel
|
|
To upload the binary wheel to PyPi
|
|
twine upload dist/*.whl
|
|
To upload the source distribution to PyPi
|
|
python setup.py sdist
|
|
twine upload dist/dlib-*.tar.gz
|
|
To exclude/include certain options in the cmake config use --yes and --no:
|
|
for example:
|
|
--yes USE_AVX_INSTRUCTIONS: will set -DUSE_AVX_INSTRUCTIONS=yes
|
|
--no USE_AVX_INSTRUCTIONS: will set -DUSE_AVX_INSTRUCTIONS=no
|
|
Additional options:
|
|
--compiler-flags: pass flags onto the compiler, e.g. --compiler-flags "-Os -Wall" passes -Os -Wall onto GCC.
|
|
-G: Set the CMake generator. E.g. -G "Visual Studio 14 2015"
|
|
--clean: delete any previous build folders and rebuild. You should do this if you change any build options
|
|
by setting --compiler-flags or --yes or --no since last time you ran a build to make sure the changes
|
|
take effect.
|
|
--set: set arbitrary options e.g. --set CUDA_HOST_COMPILER=/usr/bin/gcc-6.4.0
