jupyterHow to Enable and Verify GPU Acceleration in Kaggle Notebooks
Learn how to turn on GPU acceleration in a Kaggle Notebook, verify it works with TensorFlow or PyTorch, understand the weekly quota, and avoid common pitfalls.
kaggleJupyter cell output character truncation limit and configurability
Goal Determine whether Jupyter's default output truncation applies to each cell's combined output or to individual output streams such as stdout, stderr, and display_data, and whether the character ceiling can be adjusted without disabling the Show All behavior. Constraints and uncertainty Documentation describes automatic truncation around 10,000 characters
Database schema change persists after Jupyter kernel restart in notebook cell
Goal Determine whether a Jupyter notebook can automatically roll back a database schema change executed in a code cell when the cell raises an exception or the kernel restarts. Constraints Restarting the kernel clears in-memory execution state but does not reverse committed DDL against an external database. The %reset magic clears the user namespace without
Preserving Jupyter Notebook v5 Execution Order and Metadata When Restoring Backups
The goal is to confirm that a Jupyter Notebook backed up in format version 5 retains its original cell execution order, output, and custom metadata after being restored on a newer Jupyter environment. Verification involves opening the restored file, inspecting the execution counts, and ensuring that outputs are intact and that extensions’ metadata survive th
Jupyter Notebook output truncation limit across classic and JupyterLab
Goal: determine whether stdout and stderr character-level truncation behaves consistently between the classic Jupyter Notebook interface and JupyterLab, and whether NotebookApp.truncated_output_size is reliably enforced in Jupyter Notebook 7.x. Uncertainty: classic Notebook reportedly truncates long output near 1000 characters by default, while JupyterLab us
Does disabling token authentication and setting a password enforce cookie‑based login for Jupyter Notebook endpoints?
Goal: Configure a local Jupyter Notebook server for integration tests that avoids using real production credentials while still requiring some form of authentication, and determine how the notebook trust system behaves under these settings. Uncertainty: When the token is disabled via --NotebookApp.token='' , the server relies on a password hash or allows ano
Kaggle Notebook Toolbar Accessibility Gaps After 2022 UI Update
Goal: Determine whether the Kaggle notebook toolbar’s run‑cell button and version‑history dropdown now expose accessible names, roles, and keyboard focus after the 2022 UI redesign. Constraints: The assessment must rely on screen‑reader announcements and Tab navigation; the exact current state is uncertain because later patches may have modified the custom d
