"我应该在我的项目中使用GitHub吗?"——有抱负的数据科学家经常问我这个问题。只有一个答案——"绝对!" GitHub对于那些想要脱颖而出的数据科学家来说是一个非常有价值的平台。你可以把它当做一份在线简历，用来向招聘人员和其他专业人士展示你的代码。GitHub上有来自谷歌、Facebook、IBM、英伟达等顶尖科技巨头的开源项目，这些举措让GitHub更加受到人们的关注。如果你是数据科学的初学者，或者是专业人士，你应该有一个GitHub账户。为了节省你寻找高含金量库的时间(虽然这样的库有很多)，我很高兴在这篇文章中罗列出它们并将它们直接提供给你。这篇文章集合了各种用例——计算机视觉(目标检测和分割)，PyTorch实现的谷歌人工智能打破了用于NLP的BERT模型，提取最新的研究论文及其摘要等。为什么我们要在这篇文章中加入关于Reddit的讨论呢?我个人觉得Reddit是一个极其有益的平台——因为它有着丰富的内容,众多机器学习/深度学习专家提出的想法,一些"骇人听闻"的话题,以及开源资源，等等。我可以继续说下去我喜欢它的原因，这足以表明我是有多么的推崇Reddit——它们是那样的独特而有价值。你可以看看我关于GitHub上的顶级存储库和Reddit讨论(从4月份开始)，我们每个月都在讨论: 一月：https://www.analyticsvidhya.com/blog

There are more than a million subreddits on Reddit, according to redditmetrics.com . I wrote a script that repeatedly queries this Reddit API endpoint until all the subreddits are stored in an array, all_subs : all_subs = [] for sub in <repeated request here>: all_subs.append({"name": display_name, "subscribers": subscriber_count}) The script has been running for close to ten hours, and it's about halfway done (it gets rate-limited every three or four requests). When it's finished, I expect an array like this: [ { "name": "AskReddit", "subscribers", 16751677 }, { "name": "news", "subscribers",
