17-17: LGTM! The .idea directory is a standard JetBrains IDE configuration folder and should be excluded from version control.

15-42: Well-structured setup instructions.

The step-by-step creation and registration process is clear, well-formatted, and easy to follow. The command examples are properly presented in code blocks, and the inline explanations are helpful.


56-74: Clear verification procedure.

The verification section provides both UI-based confirmation (with helpful browser refresh guidance) and a practical Python snippet to validate the environment. The expected output example helps users confirm success.

80-84: The system kernel path remains incorrect despite previous feedback.

The python3 kernel is shown at /home/jovyan/.venv/share/jupyter/kernels/python, which incorrectly places the system kernel inside a virtual environment directory. The default python3 kernel should reside in a system-wide location such as /usr/local/share/jupyter/kernels/python3, /usr/share/jupyter/kernels/python3, or /opt/conda/share/jupyter/kernels/python3 (if using conda).

Only the custom python-testing kernel installed with --user belongs in ~/.local/share/jupyter/kernels/.

📝 Corrected example output
 Available kernels:
-python3           /home/jovyan/.venv/share/jupyter/kernels/python
+python3           /usr/local/share/jupyter/kernels/python3
 python-testing    /home/jovyan/.local/share/jupyter/kernels/python-testing

19-19: Minor grammar improvement needed.

The phrase "does not require root privileges" lacks a clear subject. For better readability, revise to "and does not require root privileges" or restructure the sentence.

📝 Suggested fix
-In this guide, we use **python-build-standalone**, which provides a *clean, dependency-free, precompiled Python binary for Linux*. This approach does not rely on system libraries, does not require root privileges. It is well-suited for containerized or restricted environments such as JupyterLab.

60-60: Consider making the PyPI mirror optional or documenting the default.

The command uses a China-specific PyPI mirror (tuna.tsinghua.edu.cn), which may not be optimal for international users. Consider either:

  • Showing the default command without -i flag and mentioning the mirror as an optional optimization for users in China
  • Adding a note that users can omit the -i flag to use the default PyPI index
💡 Suggested alternatives

Option 1: Default command with optional mirror note

-pip install ipykernel -i https://pypi.tuna.tsinghua.edu.cn/simple
+pip install ipykernel
+
+# Optional: Use a China mirror for faster downloads
+# pip install ipykernel -i https://pypi.tuna.tsinghua.edu.cn/simple

Option 2: Add explanatory note

# Use default PyPI or specify a mirror for faster downloads in China
pip install ipykernel -i https://pypi.tuna.tsinghua.edu.cn/simple

86-106: LGTM! Clear verification steps.

The verification instructions are well-structured and provide an effective way for users to confirm their kernel is configured correctly. The example output accurately reflects the expected virtual environment path.

Optional enhancement: Consider adding a brief section on how to remove or uninstall kernels when they're no longer needed. For example:

# List installed kernels
jupyter kernelspec list

# Remove a specific kernel
jupyter kernelspec uninstall python-testing

This would provide complete lifecycle management guidance for users.

Include a note on the security trade-offs and ensure readers understand this is for internal, controlled environments.
