trunk/43254ad784d7e1d1a68e88d34c03a9d555d0798f: [BE] Remove duplicate typing-extension from requirements (#174490)
A simple duplicate line was blocking developers from installing a major AI framework.
Deep Dive
A developer noticed an error when trying to install PyTorch's requirements, caused by the 'typing-extensions' package being listed twice with different version numbers. The fix involved removing the duplicate entry from one file and updating the version in another. This minor cleanup resolves a direct installation blocker for anyone setting up the popular machine learning library from source, ensuring a smoother developer experience for the project's contributors and users.
Why It Matters
Even small errors in foundational tools like PyTorch can disrupt work for millions of AI developers and researchers worldwide.
