Wonderful things I learned about onnx.js
- It does not support 1D or 3D convolutions
- Operation support is in fact really patchy for more involved models
- What is really funny - some of these combinations really lock you in - for example absence of Shape op for some backends

Comparing Popular Model Hubs - Conclusion
ONNX and OpenVino hubs are designed to make models built by other people load / work using "1 line" of code with a semblance of everything being done properly in legal terms, but there is very little incentive for model creators to share models there.
TF and Torch hubs may actually help with discovery and they are low-maintenance.
All of this is kind obvious, if you compare my conclusions with strategies of companies maintaining these, especially the no-GPL mumo-jumbo by Intel.

ONNX Models
- Looks like it is mostly community-driven
- Their submission process is mostly biased towards community uploading third-party research artefacts, though
- Though description format is plain md, it is mostly geared towards people packaging third-party research artefacts
- You MUST upload all of your models / artefacts / datasets to their git-lfs storage
- All in all of this mostly implies between the lines that your models will not be d / will be hard to maintain
- What is most sinful - if you follow their format entirely, there is no connection between you and your models users - they will just see ONNX hub repo folders and will never care about you
- No legal problems per se, but I cannot see any motivation for independent companies to share models there - you essentially upload whole packages there and they are gone for good (I believe that links inside of github are not properly indexed, but git-lfs is NOT indexed by web-crawlers for sure)
- In the end, even if you do not care about this sort of thing, and you are 100% altruistic, this git-lfs basically implies that you have to re-upload your d models on each , create a PR, etc etc - I am just lazy to do this for each model
Open Vino models
- Well, their docs format are decent
- A bit too much focus, again, on hosting third-party research artefacts and too much belief that all datasets are free and public (and that leaderboards matter)
- The big problem is that they essentially also want you to package something and relinquish all rights to this
- It is also supported by the fact that GPL licenses are NOT allowed
- So, what is my motivation to contribute as an independent company? Well, there is very little

TF Hub
- A lot of confusion and legacy between old TF / Keras / Hub models / SavedModels
- Instructions are like 10 separate documents, but after looking at examples it is kind of easy ... but the docs are very ... non-intuitive
- ~1000 models published, most of them by Google, most of them just very niche research artefacts
- Overall structure consists of models and collections. Nice tagging, nice web UI to look through the models, I see why there is so much hassle with format documents
- Zero traffic from there though =(
- Core models and community models are separated ... so I believe this is the reason. Also PyTorch hosts its hub on their main domain, whereas TF created a separate one ... you see what I mean =)
- I could fit PyTorch logic there as well, so it is nice after all!
- No focus on licensing - you can just add any license you want

Comparing Popular Model Hubs
The contenders are:
- PyTorch Hub
- TF Hub (latest PR not merged yet)
- ONNX models
- OpenVino models
So, I read the docs for all of them, created PRs for 3 of them, in the end our models were accepted to PyTorch Hub and TF Hub.
PyTorch Hub
- Instructions are literally 4 steps long
- The way the models are packaged and distributed is beautiful, clean, minimalistic and easy to use and maintain. Some great mind really designed it
- Essentially you just host your model, add a special file to your repo, torch hub just pull your repo behind the scenes and loads the model. It is embarrassingly easy
- I was greeted by Soumith Chintala himself
- After publishing, our models got a decent surge of traffic - cool!
- No focus on licensing or any similar sort of bs - you just share your models

The State of JS Inference in Browsers
Last time I looked at ONNX was 2+ years ago. It was basically nowhere. Now I decided to export our models from silero-models to ONNX and TensorFlow.
After fixing numerous issues, tldr - vanilla ONNX (via onnx-runtime) and TF models just work without looking under the hood. Ofc, I have not tested all of the teased back-ends for onnx-runtime, but it works at least on x86 w/o any issues out-of-the-box.
As for running in browsers ... my bet was on onnx.js (PyTorch => ONNX), but it looks like it is still early. Some issues I created - 1, 2. Interestingly, similar issues were addressed in onnx-tensorrt.
As for TF, I do not believe it is a go-to option just because you need to transform your model 3 times (PyTorch => ONNX => TF => TF js).
Such things looks like Sisyphus tasks, but in the long run ecosystem evolves, which is cool.

ДОКЛАД NVIDIA "Fast training with AMP/TF32 using TensorCores on NVIDIA GPU" на Data Fest + СЕССИЯ Q&A
Денис Тимонин, AI Solutions Architect в NVIDIA, расскажет об одном из самых эффективных методов ускорения обучения и инференса нейросетей - применении смешанной точности. В своем докладе Денис разберет статью “Mixed Precision Training” от NVIDIA и Baidu Research и расскажет о деталях работы с точностью формата TensorFloat32. Также мы обсудим алгоритмы, которые применяются при обучении с помощью смешанной точности и поговорим об аппаратных решениях, которые обеспечивают высокую скорость работы для форматов данных в нейросетях.
В первой части доклада мы разберем числа с плавающей точкой, мотивацию за обучением в смешанной точности, тензорные ядра, а также обучим сложную нейросеть StarGAN V2 (CVPR 2020) в режиме Automatic Mixed precision (AMP).
Во второй части погрузимся в оптимизацию работы с тензорными ядрами: разберем трюки для быстрого обучения в высокоуровневых фреймворках, C++ API, а так же научимся подбирать правильные размеры данных и слоев в нейросети для наибыстрейшего обучения.
Доклад записан на английском языке.
Доклад уже доступен на Youtube канале ODS: https://bit.ly/3kPAvPA
Сессия Q&A состоится в субботу, 26 сентября с 12 до 14 тут: https://spatial.chat/s/ods Пароль для входа можно получить тут: https://bit.ly/2GbDB1j

Also about competition.
.... why Microsoft of all people wants to train a effing TRILLION parameter transformer?
... ( ° °) because they license a 100bn one from another company.
PS
I may be wrong in the exact figures.

Microsoft ... Stepping up its Game in ML?
Wow, wow, do not close yet! I am a big MS-hater myself.
Well, an outsider / legacy player in cutting edge tech / ML, looks like with a series of well-placed decisions it may earn its place under the ML sun?
Yes, you heard me right. I am big Microsoft hater, but Just check this out:
- https://github.com/microsoft/onnxjs
- https://github.com/microsoft/onnxruntime#binaries
- https://github.com/microsoft/DeepSpeed
- ... OpenAI deal is just for hype I guess, no-one takes OpenAI seriously, right? ( ° °)
- Also I recently used Azure datasets ... it was clunky compared to S3, but beggars cannot be choosers. Download speeds were slow, but their VScode-like desktop app was ok ... but some features just did not work
It used to be a standard narrative "TF = production". But I guess a more correct one would be "Google has invested billions in marketing and it has huge captive audience".
Lately I spent some time reading TF tutorials ... and they are so needlessly difficult - they fucking invent a protocol for everything! For what PyTorch hub achieves in 4 steps, TF hub requires you to read 10 markdown docs ... written in corporate language.
So, why is this important? Because proper competition makes everything shine brighter.
Why TF 2.0? Because PyTorch 1.0 ( ° °). Now it looks like Google and Nvidia have a new real competitors in ML inference market together with Intel (which afaik is losing in general, but that is another story).
Nice!
