Top Highlights from TensorFlow Dev Summit 2020!

Introduction

TensorFlow is a popular and leading open-source framework for developing machine learning and deep learning applications. Developed and pioneered by Google, TensorFlow is a flexible and ever-changing framework favored by deep learning industry professionals and experts.

Each year, the team behind TensorFlow hosts a dev summit event that comprises two days filled with technical updates from the TensorFlow team and presentations from users showcasing amazing applications they’ve built using TensorFlow. There are also hacker-rooms, breakout sessions, and workshops.

This year, the TensorFlow Dev Summit 2020 had a different flavor to it. With the outbreak of the coronavirus in many countries, the TensorFlow team decided to prioritize the health and safety of their attendees (and rightly so!). They changed the dev summit to the first-ever live stream on YouTube and provided recordings for those who missed it.

I am thrilled to present the top highlights from the TensorFlow Dev Summit 2020 in this article. I have included the video for each talk as well so you can watch it in its entirety!

3. Collaborative ML with TensorBoard.dev

Speaker: Gal Oshri

TensorBoard is a TensorFlow visualization toolkit that is commonly used by deep learning researchers and engineers to understand their experiment results. TensorBoard lets us track metrics, visualize our deep learning model, and explore parameters among other things.

But there was a limitation – these results could only be shared in a picture format for others to review or correct. The actual implementation where the errors could be found more easily could not be shared.

TensorBoard.dev makes this task easier. With tensorflow.dev, we can upload our TensorBoard results and get a link that we can share with everyone for free! Others can easily view and interact with our TensorBoard to compare their performance or rectify our mistakes. Here is the link to get started.

Here’s the talk on TensorBoard.dev at the TensorFlow Dev Summit 2020:

 

4. Performance Profiling in TensorFlow 2.x

Speaker: Qiumin Xu

Performance Profiling tool is finally released in Tensorflow 2.x! This tool helps to improve our deep learning model’s performance like a professional player. What performance profiling does is it produces automated performance guidance and suggestions for improving the model performance and thereby increasing the productivity of performance engineers.

8 new tools have been released, 4 of which are common to CPU, GPU, and TPU. Some of them include:

  • Overview page: This tool provides an overview of the performance of workload running on our device
  • I/O Input pipeline analyzer: A most important tool to determine if there is any bottleneck present in the model or not and provides suggestions and resources for removing this bottleneck
  • TensorFlow Stats: Present statistics in a chart or tabular format

I’m sure you’ll be excited as I am to try performance profiling in TensorFlow 2.0! You can do that on this link.
