Displaying Images in Google Colab Notebooks: A Guide

Google Colab is a popular platform among data scientists for its ability to run Jupyter notebooks in the cloud. It’s a powerful tool that allows you to execute Python code, share your notebooks, and even leverage the power of Google’s hardware for machine learning tasks. However, one common question that arises is: ‘How can I display an image within a notebook in Google Colab, similar to Jupyter Notebook in Anaconda?’ In this blog post, we’ll answer that question and provide a step-by-step guide on how to do it.

Displaying Images in Google Colab Notebooks: A Guide

Google Colab is a popular platform among data scientists for its ability to run Jupyter notebooks in the cloud. It’s a powerful tool that allows you to execute Python code, share your notebooks, and even leverage the power of Google’s hardware for machine learning tasks. However, one common question that arises is: “How can I display an image within a notebook in Google Colab, similar to Jupyter Notebook in Anaconda?” In this blog post, we’ll answer that question and provide a step-by-step guide on how to do it.

Step 1: Importing Necessary Libraries

The first step is to import the necessary libraries. We’ll need the matplotlib library for displaying images and the PIL library for image processing. If you’re working with images in a machine learning context, you might also need the tensorflow library.

import matplotlib.pyplot as plt
from PIL import Image
import tensorflow as tf

Step 2: Loading the Image

Next, we need to load the image. There are several ways to do this, but one of the most common methods is to upload the image to your Google Drive and then mount your Google Drive in your Google Colab notebook.

from google.colab import drive
drive.mount('/content/drive')

After running this code, you’ll be prompted to authorize Google Colab to access your Google Drive. Once you’ve done that, you can load the image using the Image.open() function from the PIL library.

img = Image.open('/content/drive/MyDrive/path_to_your_image.jpg')

Step 3: Displaying the Image

Now that we’ve loaded the image, we can display it using the imshow() function from the matplotlib library.

plt.imshow(img)
plt.show()

This will display the image within your Google Colab notebook, just like in a Jupyter Notebook in Anaconda.

Step 4: Manipulating the Image

One of the advantages of displaying images in notebooks is that you can easily manipulate them and see the results in real-time. For example, you can convert the image to grayscale using the convert() function from the PIL library.

img_gray = img.convert('L')
plt.imshow(img_gray, cmap='gray')
plt.show()

Conclusion

Displaying images within a notebook in Google Colab is a straightforward process that can be accomplished in just a few steps. By leveraging the power of libraries like matplotlib and PIL, you can not only display images but also manipulate them and see the results in real-time. This makes Google Colab a powerful tool for data scientists working with image data.

Remember, the key to mastering any tool is practice. So, try displaying and manipulating different images in your Google Colab notebooks. Happy coding!
