pytorch-v2.0.1 cuda arm64 aarch64 torch 2.0.1+cu118 源码编译笔记【2】验证cuda安装 成功

pytorch-v2.0.1 cuda arm64 aarch64 torch 2.0.1+cu118 源码编译笔记_hkNaruto的博客-CSDN博客

由于采用/usr/local/bin/gcc编译，先设置LD_LIBRARY_PATH，再启动python3

export LD_LIBRARY_PATH=/usr/local/lib64:/usr/local/lib:/usr/lib64:/usr/lib
/usr/local/Python-3.10.12/bin/python3

import torch报错
