Summary:
For dynamic shape, if delegate output is dynamic shape, the return might be something like
(s0, x, y)
, ands0
is a sym type while others are fake tensor. In this case, we will emit the sym value (includingSymFloat
,SymBool
,SymInt
) to a unique Evalue.Since the sym type node will have an empty spec, we use the
node.meta['val']
to find out it's a sym type node.Differential Revision: D56176100
