本文主要是介绍torch-npu的安装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
pytorch与CANN的版本有对应关系，请查看网站：
https://gitee.com/ascend/pytorch/tree/v5.0.1.1-pytorch1.11.0
根据自己选定的版本，首先安装pytorch和依赖项：
# for aarch64
pip3 install torch==2.0.1pip3 install pyyaml
pip3 install setuptools根据对应版本，下载torch-npu安装文件：
https://gitee.com/ascend/pytorch/releases
安装torch-npu：
# 距离，版本自行修改
wget https://gitee.com/ascend/pytorch/releases/download/v5.0.0-pytorch1.11.0/torch_npu-1.11.0.post8-cp38-cp38-linux_aarch64.whlpip3 install torch_npu-1.11.0.post8-cp38-cp38-linux_aarch64.whl安装完成后，测试发现并不能正常运行：
# 测试代码
import torch
import torch_npux = torch.randn(2, 2).npu()
y = torch.randn(2, 2).npu()
z = x.mm(y)print(z)会报错：

EC0010: Failed to import Python module [ModuleNotFoundError: No module named 'scipy'.].
Solution: Check that all required components are properly installed and the specified Python path matches the Python installation directory. (If the path does not match the directory, run set_env.sh in the installation package.)

需安装其他库：
pip install decorator attrs psutil absl-py cloudpickle scipy synr==0.5.0 tornado安装完成后，再次测试，发现可行：
