It was said that Caffe2 and PyTorch are merging together for easier production deployment. However in PyTorch conference yesterday it seems the newly introduced C++ API will be used for production instead of converting model to Caffe2. I was wondering what’s the relationship between Caffe2 and C++ API? Specifically,

Will Caffe2 be part of the C++ API, and/or will Caffe2 be (sort of) deprecated?
In the future, which one is considered better to use for production deployment. Caffe2 or C++ API?

Thanks!
