Review Comment:

The `import warnings` statement should be moved to the top of the file.
According to PEP 8, imports should be at the top of the file, just after any
module comments and docstrings. Placing imports inside functions is generally
discouraged as it makes it harder to see the module's dependencies at a glance
and can lead to repeated imports.
References
1. PEP 8 recommends that imports are always put at the top of the file, just
after any module comments and docstrings, and before module globals and
constants.

Review Comment:

To adhere to PEP 8 guidelines, import statements should be placed at the top
of the file. Please move `import warnings` to the top of the module.
References
1. PEP 8, the style guide for Python code, specifies that imports should be
at the top of the file. This improves readability and makes dependencies
explicit.

Review Comment:

This change introduces a user warning, which is great for security
awareness. However, there is no test to verify that this warning is actually
triggered when loading from a cached pickle file. Please consider adding a test
case to `tests/python/contrib/test_memoize.py` that uses `pytest.warns` to
assert that the `UserWarning` is raised.

gemini-code-assist[bot] commented on PR #18925: URL: https://github.com/apache/tvm/pull/18925#issuecomment-4114378289 ## Summary of Changes Hello, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request addresses a security vulnerability (CWE-502: Deserialization of Untrusted Data) in the `pickle_memoize` utility. It enhances user awareness by adding a `UserWarning` during the loading of cached pickle files, informing them that pickle files can execute arbitrary code and should only be loaded from trusted sources. This change aims to mitigate risks where malicious payloads could be injected into the cache directory. ### Highlights * **Security Warning Added**: A `UserWarning` has been introduced in `pickle_memoize` to alert users about the security risks associated with loading cached pickle files, specifically the potential for arbitrary code execution from untrusted sources. 🧠 **New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** Using Gemini Code Assist The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips.
