🚀 The feature, motivation and pitch

Currently, when a user installs requirements for ExecuTorch on their Intel-chip Macbook by running the ./install_requirements.sh after git-cloning the ExecuTorch repo, the installation fails for torch versions, throwing an error and a stack trace.

ERROR: Could not find a version that satisfies the requirement torch==2.7.0.dev20250310 (from versions: 1.11.0, 1.12.0, 1.12.1, 1.13.0, 1.13.1, 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.1.2, 2.2.0, 2.2.1, 2.2.2) ERROR: No matching distribution found for torch==2.7.0.dev20250310

Alternatives

1. Return a message stating "this platform is not supported" while running PyTorch on Intel Macbooks
2. Updating documentation to add a disclaimer or in pre-requisites that PyTorch does not work anymore on Intel Macbooks.
