mbrookhart commented on issue #5231: [POC] Pattern Language, Matcher, and Rewriter V0 URL: https://github.com/apache/incubator-tvm/pull/5231#issuecomment-614321103 Yes! Fuzzy diamond matching as long as all of the nodes between the parent and the child all match the path pattern. Just added this unit test, will upstream it with the refactor: ``` # Fuzzy path/nested Diamond is_conv2d = is_op('nn.conv2d')(wildcard(), wildcard()) is_unary_elemwise = (wildcard().has_attr("TOpPattern", K_ELEMWISE))(wildcard()) | is_op('add')(wildcard(), wildcard()) reduction = is_op('add')(wildcard(), wildcard()) diamond = dominates(is_conv2d, is_unary_elemwise, reduction) inp = relay.var('input') weight = relay.var('weight') conv2d = relay.op.nn.conv2d(inp, weight) relu = relay.op.nn.relu(conv2d) relu = relu + relu tanh = relay.op.tanh(relu) leaky_relu = relay.op.nn.leaky_relu(conv2d, alpha=0) out = tanh + leaky_relu assert diamond.match(out) ``` Any patterns in particular you want to see tested?
