Slicing Numpy Arrays - Numpy For Machine Learning 2

Показать описание

In this video we'll learn all about Slicing Numpy Arrays For Machine Learning.

We'll learn how to slice a 1-Dimensional array as well as a 2-Dimensional array.

We'll learn how to take different types of slices, including negative slices and more!

Happy to have found your channel. Thanks for sharing this!

this is literally one of the best courses (arguably the best one) for numpy

dude you are amazing but only suggestion i wish you used jupyter notebook instead of sublime so that we could get the outcome on the go.

great teaching sir, but i have to say, the way you start the video with that hand gesture XD

6:58 IMO these are not the two dimensions, but two entries in a dimension. The two dimensions are given by the brackets.
Either way, good video, thanks.

Just curious, is there a way to slice one portion of a dimension and another different one of the other in a single line of code? I mean, if you want to get items (index) 0, 1, 2 from the 1st dimension and 2, 3, 4 from the 2nd one. I've tried a couple of things but it doesn't seem to be working.
