部署出现问题，是不是因为没安装https://github.com/chengdazhi/Deformable-Convolution-V2-PyTorch这个项目的原因，请问这个项目是怎么用的，没太看明白，谢谢

你好，感谢对我们工作的关注。对于DCN的安装理论上只要执行Environment setup里的这两条应该就可以用了

cd codes/model/DCN_v2/
sh make.sh

你的 DCNv2 编译错误可能是由于这条fatal error C1083: 无法打开包括文 件: “THC/THC.h”: No such file or directory，貌似是由于新版 PyTorch 已移除对 THC/THC.h 的支持，而 DCNv2 的源码依赖了这个文件，尤其是你使用 PyTorch ≥ 1.9 或者 CUDA ≥ 11.x。你可以尝试开个新的conda 环境，然后用早一些版本的Pytorch和CUDA试试看（比如requirements.txt里的版本）。

希望对你有帮助，若有新的问题也欢迎讨论。
