Report #103400

[bug\_fix] ERROR: Could not find a version that satisfies the requirement torch \(from versions: none\) on Apple Silicon

Use a distribution that provides arm64 wheels. For PyTorch, pass '--extra-index-url https://download.pytorch.org/whl/cpu' \(or /whl/cu118, /whl/mps as appropriate\). Alternatively use conda-forge, which builds arm64 packages natively.

Journey Context:
On an M1/M2 Mac, 'pip install torch' fails because PyPI has no arm64 wheel and building from source aborts due to missing MKL/CUDA tooling. You check the PyTorch install guide and see they host platform-specific wheels on their own index. Adding the extra index URL lets pip select a pre-built arm64 wheel instead of trying to compile the project.
