TVM Monthly - Feb 2019


#1

As discussed with TVM PMC, we would like to give a summary of the project per month, so that people can get better sense of what is going on in the community.

Feedback and suggestion are welcomed so that we can further improve the report. Also correct me if I made any mistake or missed anything. Thanks!

Community

In Feb 2019, we successfully released TVM v0.5 (release notes) and made the roadmap for v0.6.

The community welcomes new Reviewer Zhao Wu (@FrozenGene), Committer Jared Roesch (@jroesch) and PMC member Lianmin Zheng (@merrymercy)

TVM community has voted through Apache Incubation proposal (#2543). Markus Weimer posted a proposal to general@incubator.apache.org seeking for ideas and suggestions. The official voting is ongoing on general@ right now.

Features and Improvements

The community keeps making progress on supporting a variety of deep learning frameworks, providing better programming interfaces by improving Hybrid Script and introducing Rust frontend. We (partially) delivered major features including Quantization, Automatic Differentiation and Algebraic Data Types support.

On the forum we also had inspiring discussion about the latest ML/DL compiler techniques & designing.

More improvements along with details are listed below.

Operator Support

  • A special operator annotation.stop_fusion to prevent it being fused with previous expressions (#2624).
  • batch_matmul supported (#2561).
  • reverse_reshape supported (#2503).
  • Faster-RCNN proposal operator for CUDA (#2420).
  • Vision operator for YOLO yolo_reorg (#1941).
  • slice operator for MXNet (#2662).
  • arange supported (#2621).
  • Vision operator roi_align (#2618).
  • where operator for MXNet (#2647).

User Interface and Frontend

  • Introduced HybridModule (#2477) so that normal TVM schedule can be compiled to hybrid target, run and dumped to Hybrid Script.
  • Most frameworks have been supported in Relay, including ONNX, Keras, Tensorflow, Caffe2, CoreML, NNVMv1, MXNet (#2246). Siju is working on DarkNet.
  • Relay now supports saving and loading parameter dictionaries. (#2620)
  • Rust frontend (#2292).
  • We are now supporting Tensorflow saved model for NNVM (#2493). Relay support is ongoing (#2586).
  • Add max_num_threads to Hybrid Script, which allows users to get max number of threads for GPU targets (#2672).

Runtime and Hardware Support

  • RFC for bringing TVM to Bare-Metal devices (#2563)
  • Make external library extend TVM’s NDArray more easily (#2613).

Performance Improvement

  • AlterOpLayout pass is now enabled for x86 on Relay (#2585). It is essential to get decent performance for CNN-based model on Intel CPUs.

Documents and Tutorials

  • Tutorials for deep learning frameworks support in Relay.
  • Tutorial for running AutoTVM with Relay (#2594).
  • Document for Algebraic Data Types (#2575).

High-level Optimizations

Tensor Expression

  • RFC for formalizing Integer Arithmetic Analysis (#2588). It is aiming to perform better context-dependent analysis, bound analysis, centralized arithmetic logic and arithmetic simplification.

Contribution and Commits

Thanks Wei @wweic for providing the tools.

#2

Thanks @yzhliu for taking the lead on making the first TVM community monthly. We will keep the tradition to continue publish monthly report in the discuss forum. Please also share your thoughts on how can we improve the summary


#3

This looks great! It would be helpful if a short paragraph of summary/highlight about the major progress (other than the details in bullet lists) we have made this month can be put in the beginning.


#4

Could we also list the highlight or important discussion / questions on this discuss forum? For example like this one Google lasted work: MLIR Primer


#5

@yidawang @FrozenGene Good point. Added.

We can add an individual section if there’re more interesting topics on the forum that worth highlight.

Also listed bug-fixes.
