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

/usr/local/Python-3.10.12/bin/python3

Python 3.10.12 (main, Sep 4 2023, 10:01:29) GCC 9.2.0 on linux
