1. 查看Cuba版本

方法一

``` nvidia-smi ``` 找到CUDA Version

方法二

Nvidia Control Panel > 系统信息 > 组件 >

2. 安装Cuba匹配版本的PyTorch

https://pytorch.org/get-started/locally/

这里使用conda安装

conda install pytorch torchvision torchaudio pytorch-cuda=11.6 -c pytorch -c nvidia

## pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu116

3. 异常情况

Collecting package metadata (current_repodata.json): \ ERROR conda.auxlib.logz:stringify(163): Expecting value: line 1 column 1 (char 0)

conda config --show-sources

删除指定文件，再运行上面命令回显空白

重新安装PyTorch

4. download some necessary tools

pip install pycocotools-windows -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install -r requirements.txt
pip install pyqt5

5. Create a new interpreter based on Anaconda3 python
   

6. 安装依赖

pip install -r .\requirements.txt

7. Other Exceptions
   Error

pip install chardet

>> _pickle.UnpicklingError: STACK_GLOBAL requires str
删labels文件夹同层的labels.cache
