Location of C API

[vincent-grosbois]

Hello
After browsing the code and documentation for this project, I'm unable to find a C API / headers for oneDAL, does it exists?
It seems that these C bindings are mentionned on the Intel website, but I can't find them.
Otherwise, if they don't exist, how does daal4py interacts with the native OneDal code?

thanks !

Hi, native part of oneDAL is C++ library, there is no C API. All C++ APIs/implementations are located in /cpp directory. Currently there are two types of supported C++ APIs:

• CPU only API, which is called daal by historical reasons;
• New API called oneapi, which as part of oneAPI open specification and can run on various hardware including CPU, GPU, ...

At the moment daal4py is based on CPU only API, header files can be found here.

All Python bindings are based on Cython and part of daal4py repository.

Thanks for you answer! for some reason I thought that the python binding could only be done through pure C and not C++
