UltralyticsYolov8安装报错

Question

问题遇到的现象和发生背景

终端提示Torch因为subprocess没有安装成功，必须需要Torch才能安装UltralyticsYolo v8
我去网上寻找Torch的源代码并使用

cd Torch
python3 setup.py install

安装Torch
可是系统提示Exception: You tried to install "pytorch". The package named for PyTorch is "torch"

遇到的现象和发生背景

我想在我的MacOSX 13.2上安装安装Ultralytics
Git已经被init

用代码块功能插入代码

pip3 install pytorch

pip3 install torch

pip3 install torch vision

cd Torch
python3 setup.py install

运行结果及详细报错内容

我的解答思路和尝试过的方法

没有任何方案……

我想要达到的结果

UltralyticsYolo v8安装成功并可以使用

Answer 1

正确的包名应该是torch，而不是pytorch。安装导致错误的可能。
应该使用命令pip install torch来安装PyTorch。
可以使用以下命令来安装 PyTorch：

pip3 install torch
pip3 install torchvision

请改正安装的名称为 "torch"，不是 "pytorch"。安装完PyTorch之后，再尝试安装 UltralyticsYolo v8。
