Open-Source Python Code

Python is a popular programming language, so it is no surprise that it has a large opensource presence with many powerful projects that receives contribution from developers around the world.

Python is booming and so is its Github page. This year was great for Python and we saw some very powerful python open-source projects to contribute to. Today, we’re listing down some of the top python open-source projects; try contributing to at least one of these, it will help improve your Python skills.

1. Flask

Python flask

This is a micro web framework written in Python. It does not have form validation and a database abstraction layer, but it lets you use third-party libraries for common functions. And that is why it’s a microframework. Flask is designed to make creating apps easy and fast and is scalable and lightweight. It is based on the projects Werkzeug and Jinja2. You can learn more about it at DataFlair’s latest article on Python Flask.

2. Keras

Python keras

Keras is a neural network library that is open-source and written in Python. It is user-friendly, modular, and extensible, and can run on top of TensorFlow, Theano, PlaidML, or Microsoft Cognitive Toolkit (CNTK). Keras has it all- layers, objectives, activation functions, optimizers, and much more. It also supports convolutional and recurrent neural networks.

3. spaCy

Python Spacy

This is an open-source software library that deals with Natural Language Processing and is written in Python and Cython. While NLTK is more for teaching and research purposes, spaCy’s job is to provide software for production. Also, Thinc is spaCy’s machine learning library featuring CNN models for part-of-speech tagging, dependency parsing, and named entity recognition.

4. Sentry

top python projects

It offers hosted error monitoring that is also open-source so you can discover and triage errors in real-time. Simply install the SDK for your language(s) or framework(s) and get started. It lets you capture unhandled exceptions, examine the stack trace, analyze the impact of each problem, track errors across different projects, assign issues, and much more. Using Sentry means fewer bugs and more shipped code.

5. OpenCV

OpenCV is an open-source computer vision and machine learning library. The library has more than 2500 optimized algorithms for computer vision tasks like detecting and recognizing objects, classifying different human activities, tracking movements with the camera, producing 3d models of objects, stitching images to get the high-resolution images and a lot more tasks. The library is available for many languages like Python, C++, Java, etc.

6. Nilearn

Python Nilearn

This is a module for fast and easy implementation of statistical learning on NeuroImaging data. This makes use of scikit-learn for multivariate statistics for predictive modeling, classification, decoding, and connectivity analysis. Nilearn is a part of the NiPy ecosystem, which is a community devoted to using Python for analyzing neuroimaging data.

7. scikit-learn

Python scikit-learn projects

Scikit-learn is another python open-source project. This is a very famous machine learning library for Python. Often used with NumPy and SciPy, scikit-learn offers classification, regression, and clustering- it has support for SVM (Support Vector Machines), random forests, gradient boosting, k-means, and DBSCAN. This library is written in Python and Cython for performance.

8. PyTorch

Python pytorch - interesting projects in python

PyTorch is another open-source machine learning library written in and for Python. This is based on the Torch library, and is great for domains like computer vision and natural language processing (NLP). It also has a C++ frontend. Among many other features, PyTorch offers two high-level ones:

  • Tensor computing with strong acceleration using GPU
  • Deep neural networks

10. Gensim

Python libraries

Gensim is a Python library for topic modeling, document indexing, and similarity retrieval with large corpora. It targets the NLP and information retrieval communities. Gensim is short for ‘generate similar’. Earlier, this would generate a shortlist of articles similar to a given article. Gensim is clear, efficient, and scalable. This implements efficient and hassle-free realization of unsupervised semantic modeling from plain text.

12. Face Recognition

Face Recognition is a popular project on GitHub- it easily recognizes and manipulates faces using Python/command line and uses the world’s simplest face recognition library for this. This uses dlib with deep learning to detect faces with an accuracy of 99.38% on the Labeled Faces in the Wild benchmark.

13. Cookiecutter

python cookiecutter

Cookiecutter is a command-line utility we can use to create projects from templates (cookiecutters). One example of this would be to create a package project from a package project template. This is cross-platform, and the project templates can be in any language or markup format like Python, JavaScript, HTML, Ruby, CoffeeScript, RST, and Markdown. It also lets you multiple languages in the same project template.
