For example, you can create consistent way of handling your own generic exception type. It's very easy, but can be super useful! To show how it's working, we'll create helpful handler that...
In this post I'll show how to prepare Docker container able to run already trained Neural Network (NN). It can be helpful if you want to redistribute your work to multiple machines or send it to a client, along with one-line run command. Sample code is using Keras with TensorFlow backend. Prerequisites Already prepared Keras NN. We'll save it to...
If you came here, you probably know what is a context processor, but let's quickly recap. It's a function, that returns dictionary of values. Those values will be injected to rendering context without explicitly defining them in view. They allows us to refactor commonly used variables out of views. The most well-known context processor is Authentication, making it possible to...
You can write all code in notepad / vim / sublime text. But, does it make any sense, when there are other tools designed to help you go faster? One of them, dedicated to Machine Learning in Python, is Spyder. I've found it when I was following Udemy Deep Learning Course. And since I was programming in RStudio (R programming language) earlier,...
If you are programming for some time, you probably heard that sentence: I made that mistake many times - I've spent lot of time optimizing something that was totally irrelevant. Basically, most of the time you should focus to create readable, maintainable code. AND THEN, if something is not fast enough, yo can try to optimize it. But firstly, profile!...
