jetson编译torchvision出现 No such file or directory: ‘:/usr/local/cuda/bin/nvcc‘

1. 完整报错

jetson编译torchvision,执行python3 setup.py install --user遇到报错

running build_ext
error: [Errno 2] No such file or directory: ':/usr/local/cuda/bin/nvcc'

完整报错信息如下：

2. 解决方法

设置以下环境变量之后再执行安装命令

export CUDA_HOME=/usr/local/cuda
