如何解决opencv编译错误，libopencv_dnn.so.4.4.0，未定义对“ cudnnTransformTensorEx”的引用
- OpenCV => 4.4.0
- 操作系统=> ubuntu 18.04 x86_64
- Compiler => cmake 3.10.2
- CUDA => 11.0
- CUDNN => 8.0.2
- GPU => rtx 2080Ti
我试图在conda虚拟环境下编译它。
详细的错误描述命令“ make -j10”失败，并显示以下内容。我不知道为什么libopencv_dnn.so.4.4.0具有未定义的引用。我在github opencv问题页面上看到关于cudnn 8.0的一些固定问题。 opencv dnn现在支持cudnn 8.0吗？ 报告：
