qiuxuezhong

• nmt

  • running transformer on paddle cloud with multi-machines，with some problems:
    • stability: cored when trainer num is large，for example 8，16
    • precision: avg loss is 3.5+, the best is 2.5 when trained wite multi-cards on one machine
    • old version：only one card multi-machines
  • move newest version of transformer to paddle cloud
    • one bug to be fixed：gpu release verson of paddle won't assert when embbeding index out of range

• abacus2paddle

  • paddle cloud can afford 100+ machine for ctr trainning test
