@jinfagang i have the same problem, have you solved this problem?

[lucasjinreal]

Using my fork: https://github.com/jinfagang/DCNv2_latest

@jinfagang It works! Thank you very much!

Unfortunately it did not work for me

@jinfagang What alterations did you make in your repo?
I am trying to figure out how to solve this problem.

[lucasjinreal]

Upgrade torch 1.5

[FranciscoReveriano]

I tried that. I still end up getting that same problem. Which CUDA/gcc version are you using?
I am trying to avoid messing with the CUDA installation.

[lucasjinreal]

I only got this with torch 1.4 or > 1.4 Using my fork I solved my problem.

应该是pytorch版本的问题，有网友将pytorch切换到1.4便解决了。现在官方给出了解决方法，可见DCNv2-git。
简单来说就是将src/cuda/dcn_v2_cuda.cu 文件中的THCState_getCurrentStream(state)都替换为c10::cuda::getCurrentCUDAStream()。
