问题遇到的现象和发生背景
Jeson TX2在刷机后，想运行yolov5模型，在安装了各种库之后，pytorch和torchvision分别是1.8.0和0.9.0，不过运行还是出现版本不对的问题
运行结果及报错内容
RuntimeError: Couldn't load custom C++ ops. This can happen if your PyTorch and torchvision versions are incompatible, or if you had errors while compiling torchvision from source. For further information on the compatible versions, check https://github.com/pytorch/vision#installation for the compatibility matrix. Please check your PyTorch version with torch.version and your torchvision version with torchvision.version and verify if they are compatible, and if not please reinstall torchvision so that it matches your PyTorch install.
这是现在的torch和torchvision版本
我的解答思路和尝试过的方法
首次出现这个错误，看网上说是torch和torchvision版本不对应的问题，费好大劲安装好对应版本，同时torchvision是编译过的（网上说用pip下的会有问题）
