Interest is the best teacher, HelloGitHub is to help you find interest!

Introduction to the

Share interesting, entry-level open source projects on GitHub.

This is a monthly magazine for people who are new to programming, passionate about programming, and interested in the open source community. The contents of the monthly include: various programming language projects, tools to make life better, books, study notes, tutorials, etc. Most of these open source projects are very easy to use, and very Cool. The main hope is for you to get your hands dirty and join the open source community.

  • Those who can program can contribute code
  • Those who cannot program can report bugs in using these tools
  • Help promote projects that you think are great
  • Star project ⭐ ️

As you browse and participate in these projects, you will learn more about programming, improve your programming skills, and find the fun of programming.

🎉 And the project HelloGitHub was born at 🎉

Cherry: Easy to use text classifier. Suitable for multiple languages, with two pre-training models, using the pre-training model to classify only one line of code. Custom training with your own data set requires only ten lines of code. Easy to achieve high precision, recall rate. At the same time, the library supports custom word segmentation algorithm, classification algorithm and so on. Sample code:

>>> res = cherry.classify(model='harmful', text=['They are passionate about computers and want to learn about data analytics, web crawlers, artificial intelligence and so on to apply to their work.'])
>>> res.word_list
[(2, 'they'), (1, 'network'), (1, 'passion'), (1, '方面'), (1, 'Data analysis'), (1, 'hope'), (1, 'work'), (1, 'learning'), (1, '从而')]
>>> res.probability
The return result corresponds to the probability of gambling, normal, politics and pornography respectivelyE-03 array ([[4.43336608, 9.95215198 e-01 e-04 3.51419231, 1.68657851 e-08]])Copy the code
