If there is a mis-match between the pattern used in
FuseOpsByPattern
and the expected relax function used in a relax codegen function (e.g."relax.ext.cublas"
), this will raise an error when attempting to unpack the primitive relax function. This commit improves the error message provided when this occurs, stating what pattern was expected, and what function was expected to match the pattern.
