Docker for Data Science: What every data scientist should know about Docker

Juha KiiliJuha Kiili

Docker isolates the software from all other things on the same system. A program running inside a "spacesuit" generally has no idea it is wearing one and is unaffected by anything happening outside.

What every data scientist should know about Python dependencies

Juha KiiliJuha Kiili

Dependency management is the act of managing all the external pieces that your project relies on. It has the risk profile of a sewage system. When it works, you don't even know it's there, but when it fails, it becomes very painful and almost impossible to ignore.

Self-Driving with Valohai

Juha KiiliJuha Kiili

One of the hottest areas of application for deep learning is undoubtedly self-driving cars. We’ll go through the problem space, discuss its intricacies and build a self-driving solution utilizing the Unity game engine, training a neural network on top of the Valohai platform. Regardless of the technologies used, you’ll get an understanding of the basics as well as the code to tweak for yourself.

Asynchronous Workflows in Data Science

Juha KiiliJuha Kiili

Pointlessly staring at live logs and waiting for a miracle to happen is a huge time sink for data scientists everywhere. Instead, one should strive for an asynchronous workflow. In this article, we define asynchronous workflows, figure out some of the obstacles and finally guide you to a next article to look at a real-life example in action in Jupyter Notebooks.

From Zero to Hero with Valohai CLI, Part 2

Juha KiiliJuha Kiili

Valohai executions can be triggered directly from the CLI and let you roll up your sleeves and fine-tune your options a bit more hands-on than our web-based UI. In part one, I showed you how to install and get started with Valohai’s command-line interface (CLI). Now, it’s time to take a deeper dive and power up with features that’ll take your daily productivity to new heights.

From Zero to Hero with Valohai CLI, Part 1

Juha KiiliJuha Kiili

As new Valohai users get acquainted with the platform, many fall in love our web-based UI - and for good reason. Its responsive, intuitive and gets the job done with just a few clicks. But don’t be fooled into thinking that’s the end of the interface conversation. We know it takes different [key]strokes for different folks, so Valohai also includes a command-line interface (CLI) and the REST API.

TensorBoard + Valohai Tutorial

Juha KiiliJuha Kiili

One of the core design paradigms of Valohai is technology agnosticism. Building on top of the file system and in our case Docker means that we support running very different kinds of applications, scripts, languages and frameworks on top of Valohai. This means most systems are Valohai-ready because of these common abstractions. The same is true for TensorBoard as well.

Automatic Version Control Meets Jupyter Notebooks

Juha KiiliJuha Kiili

Running a local notebook is great for early data exploration and model tinkering, there’s no doubt about it. But eventually you’ll outgrow it and want to scale up and train the model in the cloud with easy parallel executions, full version control and robust deployment. (Letting you reproduce your experiments and share them with team members at any time.)

PocketFlow with Valohai

Juha KiiliJuha Kiili

PocketFlow is an open-source framework from Tencent to automatically compress and optimize deep learning models. Especially edge devices such as mobile phones or IoT devices can be very limited on computing resources so sacrificing a bit of model performance for a much smaller memory footprint and lower computational requirements is a smart tradeoff.
