The link to the CANN installation documentation points to a Chinese version of the page. Since this is the English documentation, it would be better to link to the English version for a better user experience.

The torch and torchvision packages for npu_aarch64 should specify the CPU-only versions by adding the +cpu suffix, similar to the npu (x86) dependencies. The installation command in Setup.md for aarch64 points to the CPU wheel index, which contains packages with this suffix (e.g., torch==2.7.1+cpu). Without the suffix, pip might fail to find the correct package or install a version from another index that is not compatible.
