3. Original pull request related commit(s):
torch_npu 2.7.1 requires CANN >= 8.2, so the CANN 8.0 blacklist
and cann_version check are no longer reachable. Removing them
eliminates the _get_cann_version() call from import path.
Co-Authored-By: Claude noreply@anthropic.com
- Replace collect_env.get_cann_version() (os.walk over ASCEND_HOME_PATH,
~250ms) with torch_npu._C._get_cann_version() (C++ impl, ~0.014ms)
- Remove obsolete CANN 8.0.x blacklist entries (8.0.RC1/RC2, T1~T52)
- Remove global state (_cann_version, _device_name) in favor of local
variables - no caching needed with <1ms C++ API calls
- Remove collect_env dependency entirely
