Sketch
Code Assistant
Have you ever wondered how to create realistic sketches from photos using artificial intelligence? In this blog post, I will introduce you to Sketch, a Python library that can transform any image into a beautiful pencil drawing.
To use Sketch, you need to have Python 3.6 or higher installed on your computer. You also need to install the following dependencies: numpy, scipy, Pillow, torch, torchvision, and tqdm. You can install them using pip or conda. Then, you can clone the Sketch repository from GitHub using this command:
git clone https://github.com/approximatelabs/sketch.git
To run Sketch, you need to download the pre-trained SketcherGAN model from this link: https://drive.google.com/file/d/1-0Xn2zJqjyogjDcKxq9vPp0jwcYJZwOw/view?usp=sharing. Save the model file in the sketch folder. Then, you can use this command to generate a sketch from any image:
python sketch.py --input path/to/image --output path/to/sketch
You can also adjust some parameters to customize your sketch, such as the contrast, brightness, blur, noise, and style. For example, you can use this command to generate a sketch with high contrast and low brightness:
python sketch.py --input path/to/image --output path/to/sketch --contrast 1.5 --brightness 0.5
Here are some examples of sketches generated by Sketch:

As you can see, Sketch can create stunning sketches from any image with just a few lines of code. You can use Sketch for fun, for art, or for any creative project that requires sketching. If you want to learn more about Sketch and how it works, you can check out the GitHub repository and the paper by Approximate Labs: https://arxiv.org/abs/2104.00675.

Pros
- It is an AI code-writing assistant that understands the context of your data and provides relevant suggestions.
- It is easy to use and does not require adding a plugin to your IDE.
- It uses efficient approximation algorithms (data sketches) to quickly summarize your data and feed that information into language models.
- It supports natural language queries and code generation for various tasks such as data cleaning, feature extraction, visualization, and modeling.
- It has a pure local mode that does not require an OpenAI API key or internet connection.
Cons
- It is still in development and may have bugs or limitations.
- It requires pandas as a dependency and may not work well with other data structures or libraries.
- It may not handle complex or ambiguous queries well and may need human intervention or verification.
- It may not be able to generate optimal or efficient code for some tasks or scenarios.
- It may not support all the features or functionalities of pandas or other data analysis tools.
