Install mmcv, mmdetection on RTX30 series

Cuda toolkit version 11.0 and 11.1 have compatibility issues,
it could make error when compiling cuda codes with RTX30 series.

So my solution was installing CUDA version 11.2 with Pytorch stable version 1.8.0 for CUDA 11.1.

• Installing CUDA Toolkit 11.2: https://developer.nvidia.com/cuda-downloads
• Installing Pytorch: https://pytorch.org/get-started/locally/

Install mmcv-full

pip install mmcv-full -f \
	https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html

I have tested CUDA-toolkit 11.2 + Pytorch 1.7.1 (cuda 11.0 version) by using command and it works fine.

pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/11.2/1.7.1/index.html

To check installation python -c 'import mmcv; import mmcv.ops'
