swig vs. pybind11?

[dan-stromberg]

Can someone please help me understand why the community edition is abandoning swig for pybind11?

pybind11 is probably nicer for Python, but I suspect it won't work well for other languages.

Also, it seems like switching to pybind is a pretty large change that may even have implications for the API. Would it make sense to migrate to pybind After the switch to python 3.x?

Was there a real show-stopping bug or missing feature preventing the continued use of swig?

Thanks!

i think one of the main reasons was Windows & Python 3, both ready now in community.
Also, pybind11 is much nicer to write bindings.

but I suspect it won't work well for other languages.

likely, in our survey noone really cared about other languages, people wanted either python + c++ backend, or c++. There's also native Java, pytorch,..repos.
