The current version (v0.2.0) covers the most common math, logic, sorting, and array-creation APIs.The roadmap target is to cover thetop 100 most-used NumPy APIsby v1.0. See the README roadmap for the full plan.Why is AsNumpy slower than NumPy for small arrays?For small tensors (e.g., 500×500), NPU kernel launch overhead dominates the measured time. NPU acceleration becomes significant starting around 1000×1000 (float32). See Benchmarks for detailed data.Do I need to manually initialize or finalize the NPU?No. AsNumpy handles device initialization automatically onimport asnumpyand releases the device on program exit. You only need to callap.set_device(n)if you want to select a specific NPU other than device 0.【免费下载链接】asnumpy哈尔滨工业大学计算学部苏统华、王甜甜老师团队联合华为CANN团队开发的华为昇腾NPU原生Numpy仓库项目地址: https://gitcode.com/cann/asnumpy创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
