How to use DCNv3 in my own network？

[Tempesting]

I've installed the DCNv3 via the whl file, but I don't know how to use it , where can I see instructions for that?

"from DCNv3 import DCNv3 DCNv3(*args)" is wrong.

You should copy the whole folder of dcnv3_ops in your project, and then from ops_dcnv3 import modules as opsm.

You can refer to this file to use DCNv3 in your model.
