[GitHub] [incubator-tvm] comaniac opened a new pull request #5288: [BYOC]
Refine DNNL Codegen
comaniac opened a new pull request #5288: [BYOC] Refine DNNL Codegen
URL: https://github.com/apache/incubator-tvm/pull/5288
With multiple output and merge compiler region support, we can now refine the DNNL codegen to support ops with multiple outputs such as `batch_norm`. This PR:
- Support operators with multiple outputs.
- Fix the issue that the second fuse run in VM will go into external functions and decompose `batch_norm`.
- Turn on DNNL `batch_norm`.
- Fix `TupleGeItem` in DNNL codegen.
- Skip MobileNet test because of the constant node issue for now.

Review comment:
zhiics previously made a PR to outline all partition function to avoid being touched by some passes such as `fuse_ops`, but you can see that before this PR the second run of `fuse_ops` pass is invoked after the inline pass, resulting in the decomposition of `batch_norm`. After this change, we inline the partition functions back after finishing all other passes so that `batch_norm` could be preserved safely to external codegen.

Review comment:
Ah I missed one line in this separated PR. We added `mod["main"] = relay.build_module.bind_params_by_name(mod["main"], params)` to this case and it results in the large contant tensor issue that we didn't handle it in this PR.

ok makes sense, but batch_norm is decomposed by SimplifyInference, fuse_ops does something else.

This looks ok to me, why "FIXME"? TupleGetItem only cares about one output.

Review comment:
yeah, if batch_norm is encapsulated in an external function, it will be lifted out and therefore invisible by simplifyinference. Later on, if we inline it and run fusion, fusion pass will see this op and complain that on OpPattern is registered for this op...

Review comment:
In terms of the semantic, if we generate a partition function like `conv2d->BN->relu`, we should have a tuple output with 3 elements `(relu_out, BN_out_1, BN_out_2)` even the rest 2 are useless. In general we should achieve this semantic, but since no one cares the rest 2 outputs of `batch_norm` it's fine for now.
