按原项目GitHub - facebookresearch/segment-anything: The repository provides code for running inference with the SegmentAnything Model (SAM), links for downloading the trained model checkpoints, and example notebooks that show how to use the model.步骤

Install Segment Anything:

pip install git+https://github.com/facebookresearch/segment-anything.git

or

git clone git@github.com:facebookresearch/segment-anything.git
cd segment-anything; pip install -e .

但 报错

https改成git后依然报相同的错，直接下载项目上传到服务器后运行

cd segment-anything; pip install -e .

配置好环境，下载checkpoint文件

打开 segment-anything/notebooks/automatic_mask_generator_example.ipynb"运行即可，或者把代码集合到同一个py文件中直接运行
