Description
为XPU下面的bfloat16单测做准备:
mean
算子的注册类型,因为:paddle/phi/kernels/reduce_mean_kernel.cc
里面已经有了bfloat16的注册;op_test_xpu.py
里面有调用mean_grad_op_types = get_xpu_op_support_types('mean')
,根据不同结果,会走不同的计算逻辑。在单测中,float16和bfloat16没啥本质区别,都属于“非float32”的浮点型。op_test_xpu.py
里面有个针对float16的特殊处理,本PR增加了对bfloat16的特殊处理,并大幅缩小这个检查阈值(不知道前一个版本中为什么放1.0这么大的数)。先拍一个0.1放在这里,后续如有需求再调整。test_adamw_op_xpu.py
里面有个地方用了self.in_type_str
,在bfloat16的时候会报错,因此改成了self.in_type
。其它:
paddle/phi/kernels/funcs/tensor_formatter.cc
,增加对float16和bfloat16的支持。要不然用它来调试的时候,会提示“unprintable type”。为了能过覆盖率检查,修改了PrintOp
的GPU单测。
