British developer Nicholas Tollervey announced the release of Mu version 1.0, a new IDE for Python. The tool is positioned as a development environment for beginners and is available for Windows, MacOS, Linux and Raspbian, the official OS of the Raspberry Pi platform. To ensure an easy start, the developers have prepared a guide for beginners working with the new IDE.

When you start the development environment, you can choose one of the following modes of operation:

  • Python 3 programmming;
  • micro: bit programming;
  • games development using Pygame Zero;
  • CircuitPython boards operations using Adafruit.

The development environment has the following capabilities:

  • markup of syntax;
  • automatic indents;
  • built-in help;
  • code checking;
  • error tracking.

According to the developers, Mu can be a good tool for beginners, but they do not expect to make this platform universal. Having enough experience, the programmer can choose a more advanced IDE.

Nvidia to Open SPADE Source Code

SPADE machine learning system creates realistic landscapes based on rough human sketches
15 April 2019   671

NVIDIA has released the source code for the SPADE machine learning system (GauGAN), which allows for the synthesis of realistic landscapes based on rough sketches, as well as training models associated with the project. The system was demonstrated in March at the GTC 2019 conference, but the code was published only yesterday. The developments are open under the non-free license CC BY-NC-SA 4.0 (Creative Commons Attribution-NonCommercial-ShareAlike 4.0), allowing use only for non-commercial purposes. The code is written in Python using the PyTorch framework.

Sketches are drawn up in the form of a segmented map that determines the placement of exemplary objects on the scene. The nature of the generated objects is set using color labels. For example, a blue fill turns into sky, blue into water, dark green into trees, light green into grass, light brown into stones, dark brown into mountains, gray into snow, a brown line into a road, and a blue line into the river. Additionally, based on the choice of reference images, the overall style of the composition and the time of day are determined. The proposed tool for creating virtual worlds can be useful to a wide range of specialists, from architects and urban planners to game developers and landscape designers.

Objects are synthesized by a generative-adversarial neural network (GAN), which, based on a schematic segmented map, creates realistic images by borrowing parts from a model previously trained on several million photographs. In contrast to the previously developed systems of image synthesis, the proposed method is based on the use of adaptive spatial transformation followed by transformation based on machine learning. Processing a segmented map instead of semantic markup allows you to achieve an exact match of the result and control the style.

To achieve realism, two competing neural networks are used: the generator and the discriminator (Discriminator). The generator generates images based on mixing elements of real photos, and the discriminator identifies possible deviations from real images. As a result, a feedback is formed, on the basis of which the generator begins to assemble more and more qualitative samples, until the discriminator ceases to distinguish them from the real ones.
