graph

does not have

to use with lower
+ precision, put it in FP32_FUNCS list,
+ - if your operator supports both FP32 and lower
precision, has
+ multiple inputs and expects all inputs to be of the
same
+ type, put it in WIDEST_TYPE_CASTS list,
+ - if your operator supports both FP32 and lower
precision and has
+ either a single input or supports inputs of different
type,
+ put it in FP16_FP32_FUNCS list,
+ - if your operator is both safe to use in lower
precision and
+ it is highly beneficial to use it in lower precision,
then
+ put it in FP16_FUNCS (this is unlikely for new
operators)

is the
