viable/strict/1770442350: [BE] Remove duplicate typing-extension from requirements (#174490)
A tiny duplicate line in a file was breaking installations for the popular AI framework.
Deep Dive
A developer noticed that installing PyTorch from source was failing due to a duplicate entry for the 'typing-extensions' package in the project's requirements file. This caused a specific pip error. The fix was simple: remove the redundant line from one file and update the version in another. The change was quickly reviewed and approved by multiple team members, resolving an unnecessary hurdle for anyone building the software directly from its code repository.
Why It Matters
Smooth installation is critical for developers and researchers relying on this essential AI tool for their work.
