A simple way to do this would be to first generate an ndarray with the proportion of zeros and ones you want: >>> import numpy as np. >>> N = 100. >>> K = 30 # K zeros, N-K ones. >>> arr = np.array([0] * K + [1] * (N-K)) >>> arr.
28 Φεβ 2024 · A frequently used function in NumPy is numpy.zeros(), which returns a new array of given shape and type, filled with zeros. In this detailed guide, we’ll explore the numpy.zeros() function through six progressive examples, from basic to advanced usage.
numpy.zeros(shape, dtype=float, order='C', *, like=None) #. Return a new array of given shape and type, filled with zeros. Parameters: shapeint or tuple of ints. Shape of the new array, e.g., (2, 3) or 2. dtypedata-type, optional. The desired data-type for the array, e.g., numpy.int8. Default is numpy.float64.
