This means that it is not possible to store two tuple fields on different devices, so we only need one virtual device for these types. More...

Detailed Description

Primitive Op(builtin intrinsics)

This data structure stores the meta-data about primitive operators that can be invoked via Call.

Low-level IR intrinsics(such as libc.expf) are also implemented via Op.

◆ IsPrimitiveOp

bool IsPrimitiveOp ( const RelayExpr & expr )

friend

Check that an expression is a "primitive operator".

Will return true if the expression is an operator which matches the form of primitive operators registered directly by the Relay codebase.

That is the arguments are all type variables, and there is a single type relation applied to the input and output types.

Parameters

expr	An expression.

Returns: Whether the expression is primitive op.
