Description
Welcome back to another comprehensive 2026 tutorial! Today, we are diving deep into a crucial topic for anyone involved in machine learning, artificial intelligence, data science, or simply running heavy python scripts. We are going to learn exactly how to change the hardware accelerator in Google Colab to enable powerful GPUs and TPUs. Whether you are training complex deep learning models, rendering massive datasets, or looking to drastically speed up your python execution times, utilizing the right hardware accelerator is an absolute game changer.
By default, Google Colab provides you with a standard CPU. While this is fantastic for basic coding and lightweight data analysis, it quickly becomes a massive bottleneck when you start working with neural networks, complex computer vision tasks, or large scale data manipulation. That is exactly where Google Colab's ability to switch to powerful GPUs and TPUs comes into play.
In this video, I will walk you through the entire process step by step, ensuring you know how to navigate the Google Colab interface like an absolute pro. Changing the hardware accelerator in Google Colab is a simple yet incredibly powerful feature that can literally reduce your machine learning model training time from hours to mere minutes. As we navigate through 2026, the demand for computational power is higher than ever. Free users generally get access to Nvidia T4 GPUs, while Colab Pro subscribers can unlock incredible premium hardware like the L4 and A100 GPUs for unparalleled performance.
Here is a detailed, step by step breakdown of the exact process we cover in this video:
First, you will need to open your browser and navigate to the Google Colab website. Make sure you are signed into your active Google account.
Second, create a completely new notebook or open an existing python notebook where you want to execute your code.
Third, direct your attention to the top navigation menu bar of the interface.
Fourth, click on the Runtime tab. This will instantly open a dropdown menu filled with various notebook execution options.
Fifth, from this specific dropdown list, look for and click on Change runtime type. A dedicated dialogue box will immediately pop up.
Sixth, in the hardware accelerator section of this dialogue box, you will see a dropdown menu. Click on it to select either GPU or TPU based entirely on your specific project requirements.
Seventh, if you are a Colab Pro subscriber, you might also have the option to select the shape of your runtime, such as enabling High-RAM. This is particularly useful if your dataset is extremely large.
Eighth, once you have made your hardware selections, simply click the Save button. Google Colab will automatically allocate the requested hardware to your session.
Finally, I will show you how to securely verify that your GPU is actually active by running a simple python command using an exclamation mark followed by nvidia dash smi.
Beyond just the basic steps, we will also thoroughly explore the real world applications of these specific hardware accelerators. We will discuss exactly when to stick with a standard CPU, when you should switch to a GPU, and in what highly specific scenarios a TPU, or Tensor Processing Unit, is the absolute best choice. TPUs are highly optimized by Google specifically for TensorFlow operations and can process large batches of data with truly unparalleled efficiency. On the other hand, a GPU provides massive parallel processing capabilities that are perfect for PyTorch, OpenCV, and almost all general deep learning tasks.
If you are dealing with frequent disconnects, remember that Colab environments are temporary. Always save your models and datasets directly to your Google Drive to prevent data loss. We will briefly touch upon best practices for resource management so you do not burn through your compute units too quickly.
