inline |
Creates a primitive descriptor from given op_desc
, attr
, engine
, and optionally a hint primitive descriptor from forward propagation.
If allow_empty is true, the constructor does not throw if a primitive_desc cannot be created. But calling next_impl() in this case will throw.
|
inline |
Advances the next implementation for the given op descriptor.
Returns:
true
on successfalse
if the last implementation reached, and the primitive descriptor itself is kept unchanged
|
inline |
Constructs a primitive_desc from a C counterpart.
Performs certain checks to make sure that the C counterpart refers to a primitive descriptor of a particular primitive kind and propagation kind.
Note: primitive_desc constructed this way does not support next_impl().
