In this tutorial, we will learn where NumPy differs from straight Python operations with the help of examples?ByPranit SharmaLast updated : April 25, 2023 What we can perform inNumPyis indirectly what we are performing in Python. However, without NumPy, there are certain things that are not ...
However, everything that I’ve shown here extends to 2D and 3D Numpy arrays (and beyond). Moreover, the conditions in this example were very simple. Having said that, you can use very complicated test conditions in Numpy where. As always, I recommend that you learn how this works by us...

I traced this recommendation in the doc to this PR by @eric-wieser: numpy/numpy#11425 However, whenever we convert a scikit-learn estimator to add array API support, the xp.where prototype in the spec implies that the second and third argument are not optional (contrary to calling np.where...
