运行Grounded-Segment-Anything报错：NameError: name ‘_C‘ is not defined_grounded segment anything

没有使用docker部署，完全按照项目中的安装步骤进行安装的，运行项目中的grounded_sam_demo.py时出现如下报错：

最终按照下面的方法解决：

解决办法：

https://github.com/IDEA-Research/Grounded-Segment-Anything/issues/436https://github.com/IDEA-Research/Grounded-Segment-Anything/issues/436问题出在GroundingDINO上

简单说就是先把GroundingDINO给卸载掉，然后cd到GroundingDINO的文件夹，执行

python setup.py build
python setup.py install

得到解决
