Let’s learn how to convert Numpy array to boolean. We will use Numpy astype method for that purpose.
Having example array we are able to convert dtype to boolean thanks to astype function. Just put dtype=boolean as an argument like in the example below.
import numpy as np
my_array = np.array([1, 0, 1, 5, 0, 1])
print(f"My array is: \n{my_array}")
my_array = my_array.astype(dtype=bool)
print(f"My boolean array is: \n{my_array}")
As you may notice zeros got changed to 0 and other numbers to 1.
