import numpy as np data = np.loadtxt('data.csv', delimiter=',', skiprows=1) print(data) Output: [[1. 2. 3.] [4. 5. 6.] [7. 8. 9.]] In this code snippet, we again import NumPy and use the loadtxt function to r
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 array: image_data=np.array([[0,128,255],[64,192,32],[100,50,150]...
In this tutorial, you will discover how to use the basic image handling functions provided by the Keras API. After completing this tutorial, you will know: How to load and display an image using the Keras API. How to convert a loaded image to a NumPy array and back to PIL format using...
