Upgrading to PyTorch-Nightly in Google Colab: A Step-by-Step Guide

If you're a data scientist, researcher, or developer working with deep learning tasks, PyTorch is likely a significant part of your workflow. However, sometimes you may need to access newer features or functionalities that are only available in the nightly builds of PyTorch. One common place to do this is in Google Colab, a popular cloud platform for running Python code.

In this guide, we'll walk you through the process of upgrading to pytorch-nightly in Google Colab, ensuring that you can run the latest code without any hiccups.

Understanding the Problem

You may run into challenges when trying to install pytorch-nightly in Google Colab, often due to using the wrong package names or installation commands. Here's a typical scenario that demonstrates this issue:

You want to use features exclusive to pytorch-nightly.

You might already have a stable version of PyTorch installed.

The command you used to upgrade may not work as expected after a runtime restart.

If you've faced similar challenges, don’t worry! We’ll guide you through the correct steps to upgrade without any stress.

Step-by-Step Guide to Upgrade to pytorch-nightly

Step 1: Install PyTorch Nightly Packages

The command you initially tried was close, but it didn’t use the correct package names. Make sure to use this upgraded command:

Breaking Down the Command:

!pip install --pre : This option allows you to install pre-release versions, including nightly builds.

torch torchvision : These are the main packages you want to install.

-f https://download.pytorch.org/whl/nigh... : This points to the URL for downloading the nightly build binaries specific to your CUDA version (in this example, CUDA 10.2).

-U : This flag stands for "upgrade" and is essential here since a stable version might already be installed on your Colab environment.

Step 2: Restart Your Runtime

After running the installation command:

Click on the Runtime menu.

Select Restart runtime.

This step is crucial as it ensures that the new packages loaded are active in the current session.

Step 3: Verify Installation

Once you've restarted the runtime, it’s always a good idea to check that pytorch-nightly has been installed successfully. You can do this by running:

This will display the version of PyTorch currently installed. Make sure it aligns with the nightly version you intended to install.

Conclusion

Upgrading to pytorch-nightly in Google Colab doesn’t have to be complicated. With the right command and a quick restart of your runtime, you can unlock the new features offered in the latest builds and keep your projects on the cutting edge.

Troubleshooting Tips

If you encounter errors during installation, double-check your command and ensure there are no typos.

Always verify if your Colab instance supports the CUDA version pointed to in the installation command.

Now you’re equipped with the knowledge to upgrade to pytorch-nightly confidently! Happy coding!
