The PR resolves the issue with "Ollama Installation." Any Ollama notebook can be selected and tested with the installation setup; the traces will show the following errors:

>>> Installing ollama to /usr/local
ERROR: This version requires zstd for extraction. Please install zstd and try again:
  - Debian/Ubuntu: sudo apt-get install zstd
  - RHEL/CentOS/Fedora: sudo dnf install zstd
  - Arch: sudo pacman -S zstd

Code Review

This pull request aims to fix an Ollama installation error by adding zstd as a dependency. The change is in the right direction. I've added a suggestion to make the installation command more robust by including apt-get update and the -y flag to prevent potential hangs in a non-interactive environment.

[gemini-code-assist]

The apt-get install command is missing the -y flag, which is necessary for non-interactive installation. Without it, the command may pause for user confirmation and cause the cell execution to hang. It's also best practice to run apt-get update before installing packages to ensure the package lists are up to date.

Suggested change

	"!sudo apt-get install zstd\n",
	"!sudo apt-get update && sudo apt-get install -y zstd\n",

[sitammeur]

This PR addresses the known issue with the Ollama installation and resolves it by using Ollama notebooks. However, some older notebooks from Gemma 2, as well as notebooks that utilize LangChain, are experiencing import errors due to compatibility issues with the new version.

To keep this PR focused, I won’t address those issues here, but I may consider fixing them in a future PR.
