This repository contains the latest apt-list.txt and pip-freeze.txt files.

Be aware that these files do not necessarily reflect the current state of the production environment, but rather the state as of the most recent submitted changes. There may be a one or two day delay to see the changes in Colab runtimes.

Colab now supports pinning a notebook to one of several past runtime versions, which can be desirable for more consistent notebook execution results. More information about this feature is available at the blog post and the FAQ. Currently available past runtime versions are as follows:

• Ubuntu 22.04.4 LTS
• Python 3.12.12
• numpy 2.0.2
• PyTorch 2.8.0
• Jax 0.5.3
• TensorFlow 2.19.0 (not included in TPU runtimes)
• R version 4.5.1 (2025-06-13) -- "Great Square Root"
• julia version 1.11.5

If you have a problem, or see something that could be improved, please file an issue. However, we don't have the bandwidth to support review of external contributions, and we don't want user PRs to languish, so we aren't accepting any external contributions right now.
