To modify the code to display the resized images in a grid format, we can make use of the matplotlib library in Python. Matplotlib is a widely used plotting library that provides a variety of functions for creating visualizations.
First, we need to import the necessary libraries. In addition to TensorFlow, we will import the matplotlib.pyplot module as plt:
python import tensorflow as tf import matplotlib.pyplot as plt
Next, we need to modify the code to resize the images. Assuming we have a list of images stored in a variable called `images`, we can use TensorFlow's `tf.image.resize()` function to resize each image to a desired shape. For example, if we want to resize the images to a shape of (64, 64), we can do the following:
python resized_images = [tf.image.resize(image, (64, 64)) for image in images]
Now that we have the resized images, we can create a grid layout to display them. We will use the `plt.subplots()` function to create a grid of subplots, where each subplot represents an image. We can specify the number of rows and columns in the grid, as well as the size of each subplot:
python num_rows = 4 num_cols = 4 fig, axes = plt.subplots(num_rows, num_cols, figsize=(10, 10))
Next, we can iterate over the resized images and plot each image on a subplot. We can use the `imshow()` function from the `Axes` object to display the image:
python for i, ax in enumerate(axes.flat): ax.imshow(resized_images[i]) ax.axis('off')
Finally, we can use the `plt.show()` function to display the grid of images:
python plt.show()
Putting it all together, the modified code to display the resized images in a grid format would look like this:
python import tensorflow as tf import matplotlib.pyplot as plt # Assuming we have a list of images stored in the variable `images` resized_images = [tf.image.resize(image, (64, 64)) for image in images] # Create a grid layout for the images num_rows = 4 num_cols = 4 fig, axes = plt.subplots(num_rows, num_cols, figsize=(10, 10)) # Plot each resized image on a subplot for i, ax in enumerate(axes.flat): ax.imshow(resized_images[i]) ax.axis('off') # Display the grid of images plt.show()
By following these steps, you can modify the code to display the resized images in a grid format using the matplotlib library in Python.
