r/Python on Reddit: Best Python Libraries for AI/ML: Which Ones Deserve More Attention?
September 23, 2024 -

Hey folks,

My colleague Nicolas Azevedo just wrote a pretty comprehensive article about Python libraries for AI and Machine Learning. It covers a bunch of stuff from basic data wrangling with Pandas and NumPy to the heavy hitters like TensorFlow and PyTorch.

I thought it was a solid overview, especially how it breaks down when you might use one library over another. Like, when you'd reach for TensorFlow vs PyTorch, that kind of thing.

Anyway, I'm curious:

  • What's your favorite Python library for AI/ML stuff?

  • Any libraries you think don't get enough love?

Here's the link if you want to check it out: https://www.scalablepath.com/python/python-libraries-machine-learning

best-of-python: A ranked list of awesome Python libraries and tools

Docopt needs to be replaced with docopt-ng. Stars aren't everything. Docopt-ng is docopt, but with testing, bug fixes, and useful error messages.

PyQt and PySide should be on there before quiet a few other libraries on there. I'd even let wxPython on.

February 15, 2023 - This library is written in C, which gives it an advantage over the standard built-in Python sequencer. Numpy arrays are better than the pandas series in terms of indexing, and Numpy works better when the number of entries is less than 50 KB. NumPy arrays are loaded into a single CPU, which can cause slower processing compared to newer alternatives such as Tensorflow, Dask or JAX, but nevertheless, learning Numpy is very easy and it is one of the most popular libraries to enter the Machine Learning World.
