This is an expanded version of Luper Rouch’s answer that worked for me to get an openmp extension to compile using both mingw and msvc on windows. After subclassing build_ext you need to pass it to setup.py in the cmdclass arg. By subclassing build_extensions instead of finalize_options you’ll have the actual compiler object to look … Read more
Try building with environment variable CC=”ccache gcc”, that will speed up build significantly when the source has not changed. (strangely, distutils uses CC also for c++ source files). Install the ccache package, of course. Since you have a single extension which is assembled from multiple compiled object files, you can monkey-patch distutils to compile those … Read more
What I ended up doing is: setup( name=”py_my_lib”, version=version, # specified elsewhere packages=[”], package_dir={”: ‘.’}, package_data={”: [‘py_my_lib.so’]}, ) This way I get to import the lib by its name, and don’t have another level of nestedness: import py_my_lib and not from py_my_lib_wrapper import py_my_lib
I’d like to add a few notes on recent developments: PEP 518, first drafted in 2016, was marked as final in April of 2020. I’m interpreting it as an invitation to use pyproject.toml instead of setup.cfg. Quoting from the PEP: There are two issues with setup.cfg used by setuptools as a general format. One is … Read more
You can see such a file in JoshData/pdfminer/MANIFEST.in or openstack/deb-python-falcon/MANIFEST.in for instance. It is a python project which uses the MANIFEST.in template A MANIFEST.in file can be added in a project to define the list of files to include in the distribution built by the sdist command. When sdist is run, it will look for … Read more
The method I normally use is to override the command in question: from distutils.command.install import install as DistutilsInstall class MyInstall(DistutilsInstall): def run(self): do_pre_install_stuff() DistutilsInstall.run(self) do_post_install_stuff() … setup(…, cmdclass={‘install’: MyInstall}, …) This took me quite a while to figure out from the distutils documentation and source, so I hope it saves you the pain. Note: you … Read more
If I understand correctly, the paths in package_dir should stop at the parent directory of the directories which are Python packages. In other words, try this: package_dir={‘package1’: ‘../Framework’, ‘package2’: ‘../Framework’, ‘main_package’: ‘src’})
The standard pkgutil module’s get_data() function will calculate the path to your data, relative to your package, and retrieve the data for you via whatever module loader Python used to import the hermes package: import pkgutil data = pkgutil.get_data(‘hermes’, ‘templates/python.tpl’) Of course in certain cases you could just read your data using a path calculated … Read more
I dug through distutils source for a day to learn enough about it to make a bunch of custom commands. It’s not pretty, but it does work. import distutils.core from distutils.command.install import install … class my_install(install): def run(self): install.run(self) # Custom stuff here # distutils.command.install actually has some nice helper methods # and interfaces. I … Read more
This is a known bug which has been patched: https://github.com/pytorch/pytorch/pull/69904 You can either use the nightly-release of PyTorch, or otherwise downgrade setup tools to setuptools version 59.5.0: pip install setuptools==59.5.0
