numkong is not NumPy; it's a separate library.

numkong.tensor

✓ from numkong import tensor

✗ from numpy import ndarray

Debug

Known issues

deprecatedIn v7.3.0, Arm NEON kernels were hardened; old code using `_x` predicated intrinsics may produce wrong results for non-power-of-two dimensions. Ensure you use v7.3.0+ for Arm SVE/SME.

fix

Upgrade to v7.3.0 or later.

affects: <7.3.0

gotchaImporting `numkong` does not automatically import `numpy`; if you need both, import them separately.

fix

Use `import numkong as nk; import numpy as np`.

affects: all

gotchaThe library uses C extensions; on some platforms (e.g., Alpine Linux), you may need to install gcc and Python headers to compile from source if no wheel is available.

fix

Install build dependencies: `apk add gcc musl-dev python3-dev`.

affects: all
