Code Review

This pull request from Snyk aims to fix a security vulnerability in urllib3 by upgrading it. However, the proposed upgrade to version 2.6.3 (which appears to be a non-existent version) would introduce a major version bump to urllib3 v2.x. This conflicts with the transformers library's dependency requirement of urllib3<2.0, which would break the dependency installation. My review provides a correction to pin urllib3 to a secure 1.x version to resolve the vulnerability without causing this conflict.

[gemini-code-assist]

This change introduces a dependency conflict that will break the environment setup. The transformers package requires urllib3<2.0, but this change forces an upgrade to urllib3 v2.x, which is incompatible. This will cause pip install -r requirements.txt to fail.

To correctly fix the vulnerability without breaking compatibility, you should pin urllib3 to a secure version from the 1.x series.

Also, note that urllib3 version 2.6.3 does not seem to exist on PyPI. This might be a typo from the Snyk tool.

urllib3>=1.26.18,<2.0 # Pinned to a secure 1.x version for compatibility with transformers
