The first step is to create a NumPy array that you want to save as an image. You can generate this array or load it from your data source. For the sake of this example, let’s create a simple grayscale image ar

You can use the following basic syntax to swap two rows in a NumPy array: some_array[[0, 3], :] = some_array[[3, 0], :] OR some_array[[0, 3]] = some_array[[3, 0]] This particular example will swap the first and fourth rows in the NumPy array called some_array. ...
pandas.Series() function is used to convert the NumPy array to Pandas Series. Pandas Series and NumPy array have a similar feature in structure so,
NP = py.importlib.import_module('numpy'); x = NP.array([1 3 5 7 9 11]); now I would like to change x(2) to 0, this is what I do now and is clearly not efficient for very large arrays in a for loop for example.
You’ll use NumPy to represent the input vectors of the network as arrays. But before you use NumPy, it’s a good idea to play with the vectors in pure Python to better understand what’s going on. In this first example, you have an input vector and the other two weight vectors. ...
