Thenumpy.expand_dims()functionadds a new dimension to a NumPy array. It takes the array to be expanded and the new axis as arguments and returns a new array with extra dimensions. We can specify the axis to be expanded inside theaxisparameter of thenumpy.expand_dims()function. See the ...
A step-by-step illustrated guide on how to flatten only some dimensions of a NumPy array in Python.
For example, if I have a 2D tensor X, I can do slicing X[:,1:]; if I have a 3D tensor Y, then I can do similar slicing for the last dimension like Y[:,:,1:]. What is the right way to do the slicing when given a tensor Z of unknown dimension? How a...
Produces inner product x1/x2: -4.0 as expected - this made me think that numpy assumes an array of this form is a column vector and, as part of the inner function, tranposes one of them to give a scalar. However, I wrote some code to test this idea and it gave some results that...

NumPy arrays are called NDArrays and can have virtually any number of dimensions, although, in machine learning, we are most commonly working with 1D and 2D arrays (or 3D arrays for images). For example, we can convert our list of lists matrix to a NumPy array via the asarray() ...
Get the Number of Rows in NumPy Array Using the array.shape PropertyThe array.shape property in NumPy is used to obtain the dimensions (shape) of a NumPy array. It returns a tuple that specifies the number of elements along each axis of the array....
For example,conditioncan take the value ofarray([[True, True, True]]), which is a numpy-like boolean array. (By default, NumPy only supports numeric values, but we can cast them toboolalso) For example, ifconditionisarray([[True, True, False]]), and our array isa = ndarray([[1,...
This is a question of documentation rather than an issue. I can't find any example of the following very common scenario: std::vector<int> some_func(); ... // We want to expose returned std::vector as a numpy array without copying m.def(...
