CoreML conversion workflow

[Boca007]

Hi,
first of all great work! :) congrats. :)

can U tell me some info about the model conversion and optimization workflow from pb to CoreML please?
Ur CoreML model have only ~57 operators, and my training pb has about 847. and when i try to quantized still has about 274, and i can not convert the quantized to CoreML at all. :(

thx very much.
