1.显卡驱动查看
nvidia-smi
2.yolo源码与模型
https://hub.nuaa.cf/ultralytics/ultralytics
https://github.com/ultralytics/ultralytics
3.anaconda
https://www.anaconda.com/download
或
https://repo.anaconda.com/miniconda/Miniconda3-latest-Windows-x86_64.exe // mini
环境变量：
C:\ProgramData\miniconda3
C:\ProgramData\miniconda3\Scripts
C:\ProgramData\miniconda3\Library\bin
4.创建python环境
conda create -n yolo python==3.8
查看现有环境
conda env list
激活环境
conda activate yolo
激活失败
conda init cmd.exe
删除环境
conda env remove -n yolo
5.安装库
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
pip install ultralytics==8.1 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install onnx -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install onnxsim -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install onnxruntime -i https://pypi.tuna.tsinghua.edu.cn/simple
(最新的yolo8改用默认GPU版的onnxruntime，要安装一下下面的库，否则ONNX转换会有警告)
pip install onnxruntime-gpu -i https://pypi.tuna.tsinghua.edu.cn/simple
修改输出维度
