If you are looking for install python and jupyter extensions offline in trae ide, you are in the right place. Trae IDE has quickly taken the developer community by storm as an ultra-fast, AI-native alternative editor. Since Trae is built on a VS Code baseline architecture, it natively supports standard VS Code extensions. However, if you are setting up your data science workstation inside secure, air-gapped, or corporate firewalled systems, you cannot access the online marketplace. To write Python code or run interactive data notebooks, you must manually sideload your tooling. In this guide, we will walk you through exactly how to install python and jupyter extensions offline in trae ide step-by-step. Let’s figure this out together.

1. Direct VSIX Offline Download Links

To run Python and Jupyter notebooks, you need two core extensions. Below are the direct, live download links for the stable Python Extension (ms-python.python) and the stable Jupyter Extension (ms-toolsai.jupyter) from the VS Code Marketplace. These links dynamically fetch the latest releases for your exact machine architecture.

Core Python Extension (ms-python.python)

Interactive Jupyter Extension (ms-toolsai.jupyter)

Looking for a different extension? You can download any VS Code extension manually for any platform using my online VSIX Downloader Web App. Just paste the Marketplace URL or Extension ID and grab the file in seconds!

2. How to Search and Download VSIX Manually (The Fallback)

If you need custom development extensions, you can manually grab VSIX files either using our simplified web app tool or searching Microsoft’s official repository.

Method A: Using the VSIX Downloader Web App (Recommended & Easiest)

To let our automated script bypass security blocks and bundle the direct platform packages, use the web downloader:

  1. Open the VSIX Downloader Web App in your browser.
  2. Navigate to the standard VS Code Marketplace, locate either the Python Extension page or the Jupyter Extension page, and copy its Extension ID.
  3. Paste the copied ID into the search input of the web app downloader.
  4. Click **Download** to pull the clean, latest architecture-specific VSIX package instantly.

Method B: Extracting Directly from the VS Code Marketplace

If you prefer extracting raw files directly from Microsoft’s catalog:

  1. Go to the official VS Code Marketplace.
  2. Search for “Python” or “Jupyter” (developed by Microsoft).
  3. In the right-hand sidebar under the “Resources” section, locate and click the “Download Extension” link.
  4. Save the resulting .vsix file to your local computer (e.g., in your Downloads folder).

3. Manual Sideloading in Trae IDE

Once you have successfully downloaded the offline VSIX packages, sideloading them into Trae IDE is incredibly simple. You can choose between the Graphical User Interface (GUI) or the Command Line Interface (CLI).

Method A: Using the Trae GUI

  1. Launch Trae IDE on your computer.
  2. Open the Extensions menu on the left side-panel (or press Ctrl+Shift+X on Windows, or Cmd+Shift+X on macOS).
  3. Click the Options icon (three horizontal dots or gearbox) in the extension search bar.
  4. Select “Install from VSIX…”.
  5. Navigate to your downloaded Python VSIX file, select it, and click Open. Once completed, repeat the process for your Jupyter VSIX package. Trae will instantly unpack and configure both!

Method B: Using the Trae CLI

Just like VS Code, Trae provides a command-line interface. To install via terminal, run:

trae --install-extension /path/to/ms-python.python.vsix
trae --install-extension /path/to/ms-toolsai.jupyter.vsix
