I tried and it returns 'cpp' as expected. First, make sure you use the correct commands: python setup.py build --cpp_implementaion python setup.py install --cpp_implementaion
Second, Where do you put your .py file to check api_implementation.Type()? Make sure your file does not under protobuf/python (DO NOT in the same directory as setup.py) On Fri, Jul 29, 2016 at 12:30 PM, Feng Xiao <xiaof...@google.com> wrote: > +Jie > > On Fri, Jul 29, 2016 at 10:10 AM, Oi Lee <lee...@gmail.com> wrote: > >> I initially used a pure python implementation of protocol buffers, but I >> changed it later to use the c++ library implementation.
